How to fix a low water pressure and flow problem on a brand new build house.
As you will see in this video the water pressure on this house is really bad, to the point of the shower upstairs doesn’t even work… it dribbles out of your lucky.
Water flow rate upstairs is around 3/4 litres a minute... this is how to fix the issue
Fitting the Salamander Home Boost Main booster solves the problem and now the house has the water and flow rate it should have….. 12litres a minute…

I actually work at salamander pumps and to see this pop up as a recommended video is pretty cool! nice to see our product is proving good use for your family!
Nice one mate….. yer the salamander team is great, I was with them last week at Installer Show👍🏼👍🏼
I would have checked the flow rate without the stop tap on. I work on many new builds, seen main stop taps full of stones and grit. Even had a situation like this, and it was to a blocked water meter in the boundary box.
Feel sorry for your son Mark ‘cos everybody has to live somewhere, but the developers couldn’t care less so long as they’re selling houses. Wouldn’t have a new build as a gift. Good job your son has a brilliant dad. Keep up the good work Mark
Thanks mate…..🙏🏼🙏🏼
It’s so bad isn’t it….
Great piece of kit Mark, bet you were loving the press gun under that sink, quick safe and sound install. Thanks buddy, will have a look at one of those for my property!!!!
Thanks buddy… yer it was a dream under there
Been waiting for this video. The results are excellent. Like I have said before its not just new builds that struggle. Will have a word with my plumber about this. Great video Mark thanks
Great outcome wasnt it buddy 👍🏼👍🏼
@@MJTiffPlumbing Another freebie Mark. LOL
Thanks Nigel - @MJTiffPlumbing has done a brilliant job of explaining and demonstrating HomeBoost!

You should charge that work to the house builders disgusting …
I will be buddy 👍🏼👍🏼
Not likely they haven’t set the main pressure at the street income being that the development isn’t finished yet?
@@Mr_Ashley I was thinking the got some small bore pipe as bypass feeding the main supply to a few streets that aren’t fully finished, accounts for the pretend 1.5
@@MJTiffPlumbingplus the price of running the pump forever. 😂
Hi, I have the same Salamander booster fitted on the main but boost the water pressure because my water softener doesn’t work without the pressure. Since the plumber connect booster when I on the electric switch it doesn’t work with booster and I have no clue what’s wrong. Is it a brand?new booster. I am wasting all my money on plumbers but couldn’t sort of the problem yet. I really don’t know who to trust. I really need a help
Wow amazing results Mark well done buddy and thanks for sharing ♥️👍🏼💐😘
Thanks mate
Ive just ordered mine so hopefully i will be installing it on Saturday. Great content as always 👍
They are very good mate…. Let me know how you get on👍🏼👍🏼
Glad you put this video up just been looking at one of these for a customer of mine so nice to see one in the real world. I did some work on a site in sapcote near Hinckley a 5-6 years ago and the developers hands were tied by the water supplier they would only guarantee 1 bar static !!! Stupidly architect had the combi on the 3rd floor had to put a pressure test pump on the filling loop to top the pressure up just to get the boilers to work! The water supplier did eventually turn the pressure up took a lot of kicking and screaming of the developer and the homeowners.
They are great products and as you see work very well👌🏼👌🏼
Developers are a joke sometimes
Two thumbs up for the Salamander boosts. I installed one of these at our old property and it really made a huge difference.
Great ain’t they buddy👌🏼👍🏼
Thanks for positive feedback. Hope our pumps will continue to make a huge difference 👌🏼
Quality as always 💪🏻
Thanks mate
Very impressed with this video as i want to increase our pressure and had no clue, love DIY and willing to give anything a go within reason, after watching this video i will be on the phone to Salamander in the next couple of days. Have to agree with you about new builds and snagging and the work of so called professionals, once again thanks and a new subscriber
Thankyou mate…. And welcome to the channel
Great video thank you.
The waste is shocking too, bang in the middle of the base unit, they could've gone back and under and your lad could have had a shelf. Like you said... New builds.
New builds are so bad
Nice one fella! Interesting to see these pumps in use!
Thankyou David…… you’ve guessed it, they are the next big ting in home boost mains pumping😝
@@MJTiffPlumbing sorry mate I'd meant *not very interesting
Nice. I have heard mixed reviews with these pumps. I have never fitted one. But what I have seen of them I definitely will 👍👍
I’ve fitted a few and they are superb to be honest….. as you can see with the results👍🏼
Excellent plumbing fixed. I'm just very impressed with the pipe press work and tool. It makes a lot easier for working in confined spaces, and the copper is nice to look at with the home boost salamanderpump attached. Perfect fit 👌
Thanks buddy
You're right. Mark have done a great job 👍🏼
Brilliant bit of kit - very tidy install too - lucky lad
Thanks buddy
Very good information thank 👍👍
👍🏼👍🏼
Good video mark 😊
👍🏼👍🏼 thanks pal
Nice job 👏. I have to use press in commercial premises for under sink water heaters and TMV installations . Takes a lot longer than soldering depending on access and now my jaws stick on the fittings after pressing which is a pain 🙃.
Yer mine have done that a few times 🤔
5 stars 🌟, been waiting for such a vedio 🎉
Thanks buddy 👍🏼👍🏼
Wow that indeed is great!!
Isn’t it just
Nice work
Thank you! Cheers!
Great video- Mark, What's the purpose of Pressure Reducing Valve being there- Thanks' in advance.
After 30 years using press mate you learn over time to crimp sections up then offer the section up and crimp one joint in place when it’s in tight places 🤘😎🤘
Cheers buddy…. I’m getting to grips a bit more with it
@@MJTiffPlumbing I like what you did there 🤣😂🤣😂🤣😂🤘😎🤘🫖☕️🍰
Hi mark , so proud of u when I first started watching you about a year ago now, your views have gone up really quick, well done pal
Thanks buddy….. appreciate that
Evening Mark. Seems to be a common theme, new builds & really poor mains pressure. You may well end up fitting a few more of those Salamander's once your sons neighbours see what he's got! I've given up using brass olives now for that very reason you've encountered. Always try and use copper olives now, especially 22mm.
Yep I think I may very well be, what a massive improvement👌🏼👌🏼
I have been throwing out brass olives and putting in copper for years except on chrome. Just a shame generally I have to buy them online
Really interesting to hear that it seems to be a big problem in new builds!
Very impressive outcome.
I have never fitted mains pump despite this being my 40th year accept for commercial properties.
I would definitely fit one now if come across same scenario.
What a top dad fitting for your son.
Thanks buddy…. They are a good product when you need to use them
@@MJTiffPlumbing Will you be at the NEC Installer
That pump looks brilliant but wouldn't expect that sort of pressure in a new build! Be interesting to see comments what minimum pressures should be 👍🏼
Pump is great 👌🏼👌🏼
A problem which would have to be fixed by the builder under warranty.
Good job, nice to see no plug socket under the sink
Would of been handy to have one under there to be honest, nearly all new builds now they fit a double socket under a sink
If your sons place is like this the entire estate probably is. We come across it a lot in Sussex where they haven't turned the local boosting station on yet due to the sites not being complete or when they have they haven't flushed the mains so the filters on the pressure reducers are clogged.
For anyone wondering why the pressure regulators are put in it's due to warranty on the fittings in the property. They can't comply with NHBC scheme if they don't put the relevant measures in place, sadly they will still try to worm their way out of ever paying out for messing up on new builds.
Yep… they tick the boxes so that they then don’t have to come back it seems
Great vid Mark! How do you like the press fit? I'm renovating my place and trying to pick between copper press fit or pex from Zurn. Would you recommend one over the other? Cheers
Yer the press is getting there….👍🏼👍🏼
Never even knew you could boost a main..thanks
Now you do 👍🏼👍🏼
There is a common misconception that you cannot boost a home’s mains water supply. However, this is not the case. The Water Supply and Fittings Regulations state that you can boost mains water if the pumped mains water does not exceed 12 l/min.
I've never seen such awful mains water pressure outside of central London. Good job M looks neat. I think it's around 1 bar minimum for most water companies but most places get around 2.5-3bar
Yup it's one bar although many appliances need a bit more
Thanks guys….. so so bad isn’t it
Press fit install looks neat, felt like a magpie getting excited by the shine on the fittings 😅
Hahahah thanks buddy
Use long stem drain offs in press if you can get them mate I think the little ones don't quite locate, they def don't with my rems gun but it is the older model so might be okay with yours 👍🏻
Yep that’s what I use mate 👌🏼👌🏼👍🏼
H mark it’s a bad job having to fit one of these in a new house but I was impressed with that pump seen them advertised but never had the need to fit one 👍
They are very good products when you need to use them
@@MJTiffPlumbing Mark, thank you for your trust and appreciation of our pumps.
Thanks
👍🏼👍🏼
Nice bit of kit that matey! Hope he bought you a beer or two 😜
I think I had to buy them aswell🤣🤣
@@MJTiffPlumbing ahhh mate gutted…. That’s it…. Next weeks video to be titled…. How to REMOVE a pressure boost pump 😂😂😂
Now you will find all the leaks on that shower ❤
Don’t say that 🤣🤦🏻♂️🤦🏻♂️
Did you close the stopcock in inside the property and make sure the meter is not spinning as also a leak on the incoming mains supply can cause loss of pressure
Hi mark great video. I’ve actually had one of these waiting to be fitted for a while after a new water main didn’t really help our flow rate. What’s the shower like when there’s also a tap on downstairs? Thanks
Exactly the same mate…. They are brilliant
One of my pet peeves as an electrician is space saver cookers in a standard space. Mainly because landlords replace their tenants ovens with the cheapest they can get a hold of and is always a space saver. I feel bad for the tenants putting them in with a huge gap food and other crap will fall down.
👍🏼👍🏼
Big difference in the pressure,
It’s mental how they can hand over a new build with crappy pressure on a shower
The press fit is a nice clean looking job,
👍👍🤜
Thanks buddy….. 👍🏼👍🏼
Yer it’s loads better now, and I’m getting to grips with the press stuff👌🏼
Great vid, thank you for sharing the info. Is there any data on the average household usage this would increase the kWh? Just curious what your lad would now need to pay extra on his bill because the builders signed it off.
It’s VERY minimal but now has water coming out the shower so it’s all good
Pull water savers out of the fixtures and check the aerators. Debris from the new construction is likely in the aerators cause newbies don’t remove them before turn on the fixture; upon installation. Another trick is a “reverse blow”. I mentioned that only cause low pressure usually unrelated to the incoming pressure to unit or property. Nice vid. The installation of the product is delightful. You’re an inspiration to us all. 👍 I get excited about plumbing every day. A new adventure every day
Thanks buddy
I haven't heard of reverse blow before. What is it?
You are so right about the quality of work on new builds. These developers dont give a S##t . To be fair to the tradesmen, they are probably treated like s##t and paid peanuts so why would they be bothered to do a good job.
Unfortunately I think your right
I have to disagree on that. All because you think you should be paid more, doesn't mean you should do a crappy job. Do proper job, and continue to look for a better company that will pay you better.
Not all new builds are bad, we have been in one for a couple of years and barring a few minor snags, the house and the development surroundings have been brilliant. Maybe depends on who is building them. I would suggest a bit of research before you buy. Trades on our build must've been superb workers.
Part G of the building regs limits water use and often restrict its are fitted to reduce flow.
Reduce it to the point of nothing coming out of a shower and 3/4litres a minute out a bath… this is just shockingly bad development and zero care for getting it right imho
Great video Mark. I have a question. Can you install a booster pump prior to the PRV on a unvented hot water cylinder installation? Would it work? Regards Rich
This is for a combi system only……
You would need a tank boost I think
Hi mate we’re did you get that measuring cup from nice bit of kit thanks
Plumbase buddy…. Flow test cup
Hi mate, i live in a new build. i have noticed mine is rubbish with only getting the same litres per minute. is there any other restrictors put into place that causes such rubbish flow? i have a 32kw boiler vailant. is there a reason why these new builds get such crap flow rate?
Look on the bright side, you could have a whole new build estate to install boosters 👍
Hahaha very true
Great video Mark. May be the answer to my prayer. Shower in our ensuite 2nd floor is rubbish but I am not sure if this device will do the trick? How can I find out?
Speak to Salamander direct mate or look on there site
make sure u fit a pressure reducing valve be fore the pump as tested to 10 bar but have exploded. in spiked supply conditions
There is buddy…….
Good video 👍 you might have just saved me a few quid by thinking about changing my combi! What’s the cost of these pumps? Struggling to find it on their site.
Do a Google search buddy, they will come up👍🏼👍🏼
Hope you got a good Father’s Day present for that 😂
🤣🤣👌🏼👍🏼👍🏼
Great fix mark with the pump..👍fitted a few myself ...but a new build with very poor pressure from a new plastic incoming main supply..🤔 is not acceptable 😡😡keep up the great work...👍
Thanks buddy….. worked a treat
Thanks for positive feedback. Hope you will continue to work with our pumps 👌🏼
I had that on one of my new builds the problem was the waterboards contractors got ballast in the open ends took ages to clear the main
👍🏼👍🏼
Im amazed the houses combi boiler works with low water pressure. My sisters area cannot have combi boilers for this reason
This is where the Salamander Home boost comes into its own….. boosts the main👌🏼👌🏼
Hi Mark I work on new builds. Mains pressure only has to be 1 bar. 6 litre per minute flow restrictors to kitchen and 4 litres to basins, that's current regs. It's all about saving water as all properties are on water meters. You could have removed the flow restrictors
The fact that I didn’t remove the “flow restrictions” and now we have 12L per minutes shows there is no flow restrictions 😉
The main is the issue….. as shown as it was nearly coming out the shower
i like your comment when you said you can just about hear it sound like gonna take off lol will that boost work if 2 showers are running as my mains pressure is fine if one bath or shower is on but when both are on pressure drops would that help
Still holds 12L per min….. it’s a great product👍🏼👌🏼
HomeBoost will boost the mains to 12L/min but this'll be shared across all open outlets, so if 2 showers are running they'll each received approximately 6L/min.
Need plastic surgeon on the bottom of that cupboard buddy! New build eh? Very neat install, great work 😊
Brand new……🫣
Wow look at that trap assembly
Great isn’t it
Where to buy the water flow cup please? Thanks.
Toolstation or Screwfix
Great video mate, invest in the Milwaukee M18 Fan, best £85 you will ever spend. We use ours all the time.
I bought one the day I filmed this… went for the M12…. It’s perfect👌🏼👌🏼
Hello mate will that help with pressure between the kitchen and bathroom wen two taps are being used. Cheers pal.
Yep…. No pressure or flow drop now
Our shower is up and down because the pressure is just too low. this looks like a fix!
👍🏼👍🏼
need to buy that water cup tester,get proper messurement of flow,then can make a decision,how to fix it,go back to collage stuff,draw water main on a peice of paper,size of pipe,then were it goes,what it got to feed,drain on the pipe,size the pipe to supply the load required ,sounds a lot ,but easy to do ,not take long ,takes me back to my city guilds days ,level 1 ,2,3 ,learn stuff that i thought i never needed,i like to solder pipe,but being in the real world of plumbing ,people houses,need to know circuit design,load,then can fix any think,like the romans sent water miles,to towns ,and sewage,and the canal system of the victorians ,went every were,a lot of water,and had to be flat too,old school knowledge,my house had lead pipe ,3/4 inch and feed house,sheds,garage,pond,out side taps,was fun working out pipe sizes to make it work,you can down load a pdf of city guilds water pipe regs ,size and length ,for volume moved,that water cup is a very powerfull tool,gives you data,at source,running water and static water
Should you put the pump before the reducing valve?
Nope…… needs to go as I’ve fitted it👍🏼👍🏼
Why do you need to re-fit the reducing valve when the pressure is low? I don’t have one on my setup as incoming mains pressure is only 2 bar
Incas the pressure is ever turned up… we know it will be at 3bar max
How they specified a combination boiler.with 9 l/min when the c24 ( which is the smallest logic ) is 9.9 l/min @35degree celsius rise I don't know.but hay ho !
I remember I fitted one of those salamander tap boost pumps about 7 years ago in a 10th floor flat .I had never fitted one before and was sceptical.but I did everything it said it would.and as far as I know still working today.
Water companies I think are committed to providing a minimum of 0.7 bar .or aim to provide 1.0 bar of at the end of there communication pipes.
Fantastic video as normal.
Thanks mate….. yep so many red flags on this is unreal..
At least the Home Boost worked👍🏼👌🏼
Thank you for the excellent feedback!
Impressive bit of kit that is, new builds are shocking for snagging 🤷♂️
It’s brilliant, I’ve fitted a few and all given great results
When I had my mains redone I was told by the undertaker the minimum was 9ltrs at the meter but I would expect different on a new build. Good vid mate👍
Thanks mate….. yep not even 4 litres per minute upstairs
Cracking bit of kit that, totally unobtrusive as well.
They are brilliant buddy
Hi mark couple of questions 1.do you not need a non return valve on the main in england and 2.why did you put the pressure reducing valve back in.cheers
Pressure reducing valve because if they do sort the issue and the valve wasn’t on it could send too much pressure in
No need for a DCV as it’s within the unit
@MJTiffPlumbing I meant on the original pipework with the dcv.i see what you mean with the prv.thanls for replying
Great bit of kit that, I would be handing a bill to the developer, there is no way that was acceptable, especially with a combi fitted on it.
I’d be inclined to drop some flyers around the estate, offering everyone a price on installing them, you’ll clean up😀
Yep I will be speaking to them very soon
Is there a pressure regulator outside houses as my neighbours have better pressure
Nope
If I bought a new build and my shower and pressure was that bad I would ask for it be fixed by the housing company immediately,I would not spend a penny on it.
Do you think we didn’t try…. Trust me…. They didn’t want to know
I went to a house that was 10yrs old that had rubbish flow / pressure. Upon investigation we found the water had been capped in the street in the passed and rather than the cap being removed for the correct fitting someone had removed the cap.... Filed it down a bit then put the cap back on so the water was squeezing through a small gap. 😂😂
🫣🫣
That shower was a joke, I’d have been back into the builder to sort that at least! Jokers
Oh mate, I’ve tried, phoned, my lad has phoned and nothing…..
Great vid, But a random question why do you have a tent box on your van?
Thanks mate….
“Why do you have a tent box on your van”………
To go away camping with….. why else would you have one🤣🤣😝
@@MJTiffPlumbing You must do a lot of camping! When is the press fitting price video coming out?
nice place to bring the waste bang in the middle of cuboard lmao
Oh don’t get me started on that aswell….. unreal ain’t it🤣🫣
Water companies have to provide (to the water responsibly boundary) for a single domestic building 1bar whilst running a flow of 9lpm. When on a shared supply these go up…e.g 1bar with 18lpm flow for 2 props.
Some areas are just low pressure because they may be high up a hill however water companies are now fitting PRV(like the domestic one but a lot bigger and more sophisticated) on large water mains outside to pressure manage entire water networks. They are well within rights to do so as it’s all regulated by ofwat…just annoying for everyone else to adapt their plumbing to suit.
Shocking isn’t it…. Wasn’t even 4litres per minute upstairs
Interesting , are there flow restrictor’s on the taps ?
Greetings from Australia, I’m sure you have , normally I’d check from outside , see what pressure is like outside coming in at the main or at the water meter outside .
Does yr local utility guarantee a certain mains pressure ?
Why is it so under pressure / flow in the first place ?
BTW 33 degrees c , is winter in Australia …😂.
Thanks for the comment mate….
No flow restrictions or anything, just really bad water pressure!!!
@@MJTiffPlumbing interesting thanks. “ Sydney Water”, here in oz, guarantees us 500 KPA as a minimum to a domestic household about 75 psi … used to be much higher actually. The pump system is great I’ll research them here .
great job mark, but missed the snagging list from new build out! was looking forward to having a laugh
👍
Hahaha I should dig it out…. Complete joke
Can this be used with a fortic boiler please if not what booster do I need please.thank you
Only for combi systems this one
I need this in my life
They are great👍🏼👍🏼
I hope you gave the builder your bill!!
They are being so bad with this…. I am taking it further
Was that bath shower mixer thermostatically controlled, looks like you'll get a job for putting the pump in all those houses, well done.
Yep thermostatic valve in it
I hope yours doesn't sound like a jet engine on take-off power after a couple of months! Plumber installed my first Homeboost (bought from Screwfix) just under a year ago and within 3 months it started making an unholy racket, like a grinding noise as though a bearing was failing. Took a sound recording and sent it to Salamander Tech Support by email and to their credit, sent me a replacement pump in the post within a week. Told me to scrap the old one too, as no need to send it back. They also transferred the warranty over to the new serial number. New pump installed at end of March 2023 but unfortunately, after again only 3 months, the pump is making the same horrible grinding noise. Various online reviews suggest noise can be reduced by cleaning out the filter washer, but mine didn't need cleaning. Now considering other options, including the Stuart Turner Mainsboost as I don't think the Homeboost is up to the job unfortunately.
By the way Mark, Salamander states in the instructions to flush the air out of pipework and pump with mains water before turning on the power, or damage could occur to the pump. 😉
There support is spot on to be fair…… 👍🏼👍🏼
Also it was flushed through….. some things on video are done at various times and edited together buddy 😉
Terrible pressure for a new build the pump should have been fitted from the start hope you had a good fathers day present for your work ha ha
So so bad…. And the developers didn’t want to know
I would have taken that up with the building constuctor that is clearly a site issue
If they would of replied to the 10+ phone calls and emails I would of
It comes to something when the pressure’s so low they don’t even have to bother nipping up the olives. Is that one of the new estates in Warwick?
Yep new estate on Europa way…
New build with pressure and flows like that, as somebody who bought one, I'd be going ballistic at the builder and getting them to fix it under warranty rather than relying on trickery and pumps - my guess would be they crushed the main. I had a leak on mine and I didn't know for six months because there was no drop in pressure - first I knew was a 3 grand water bill; I was talking to the guy from the water company and he was saying about how the mains are supposed to be laid inside sand to protect them but they never do it's just type 1 compacted in and it causes all sorts of problems.
Trust me I tried….. they went silent
@@MJTiffPlumbing well, that's what NHBC et al are for? Anyway, sucks :(
Nobody comments on the sink waste pipe in the middle of the cupboard??😂😂. Shocking! My lads did that I'd sack em! I wouldn't be given a new build! And tbf, I wouldn't hire 3/4's of the plumbers that kit em out! Quality is out of the window nowadays!! I'm on price.........😢😂
Exactly mate
Good job done. I refuse to fit any salamander pumps anymore. There follow up service is appalling.
Always great service whenever I’ve dealt with them… great products
Couldn't you take the pressure reducing valve out? Or would that invalidate the new build warranty?
It’s fully open so makes zero difference 👍🏼👍🏼
@M J Tiff Plumbing I heard you say it was open fully, just thought there was no point keeping it.
Does this booster have the same effect when you have a dishwasher a washing machine and a shower on at the same time?
Indeed it does mate
do we need a pressure reducer valve when connecting the pump? they work opposite eachother.
Yep
Could you tell me please whether valve does not make the pump hot and burn? In other hand, without pump the tabs do not stray banging noise? Especially washing machine and dishwasher. I am curious because this what exactly what I am going to do but without valve I have problem with noise of banging!! So I wonder with pump the noise coming back or not.
Hi Mark, that water pressure in a new build was terrible, the pressure or lack of it at the shower, was horrendous.
How that passed building control/snagging I will never know.
It looks like the pump has done the trick for your son, at least he can have a proper shower after work.
I think the job using pressfit looks ok, although it is out of sight under the sink, a great looking job.
Have a great week and as always, take care, regards, Chris. 👍👍👍
Thanks Chris….. shocking isn’t it what these new builds are putting out
@@MJTiffPlumbing yep it is mate, I have seen inside some new builds near my house, the workmanship is abysmal from all the trades.
I would not put my name to any of the work and the properties are very expensive. Hope your son is happy with his new house, cheers 🍻👍👍👍
@@MJTiffPlumbing At least there was a Pressurised Combi Boiler in situ, rather that those Gravity fed Boiler systems with Vented Cylinders in an Airing closet, operated off Header and Expansion tanks in his home then he would have been in a whole lot of Pain, no more ,"Clerks of Works" everything fudged and signed off by the Builders agents [ Architects] as being," SUBSTANTIAL COMPLIANCE "what could go wrong.
On a new site I've seen a 37kw storage combi with flow restrictors on basins and a temperature mixing valve set to low 40s C on bathrooms bath tub !
On a seperate note if you have 12+ lts min out of hot tap you may depending on the size of combi end up with poor dhw temp when incoming main drops in temp.
