thank you. Rang a plumber quoted £60 then he didnt turn up. Bought the valve and ball and watched you. Job done. Hardest part was getting into the loft.
Yes a bit hot today.
Thanks Al. You're a lifesaver. My Mum's part 1 Portsmouth on her F&E tank has started dripping and overflowing. I've got a ball valve repair kit with new washers, plastic seats, etc.
This vid will help get the valve out, and when you do the part 1 overhaul vid, I will know how to service the valve.
Many thanks for your excellent and enjoyable vids. Good to have the knowledge of a pro. Keep up the hard work and thanks again.
That's an absolutely BRILLIANT video !! Clear, concise and short. Delivered and presented in a warm and friendly manner.
Fabulous ! Thanks friend for posting this.
No problem.
dereton33 I would feel very confident having you in my home doing work you seem like a nice man 👍🏼
This lads videos are brilliant. Legend.
Thank You so much for this. I managed to follow your video (after watching it a few times) and got the parts and fixed the new ball valve. No more pouring water from the back pipes.
You, Sir, are a Gem.
No problem Janet.
Big thank you to the gentleman who made this video. From me not even knowing what the overflow pipe was for to following this instruction and completing the job in 10 mins deserves thanks. Same spec on mine - old part 1 valve now replaced with part 2 valve. And job all done in 10 mins! This video will tell you all you need to know. Excellent! Thank you dereton33.
No problem. Al.
Thank you so much for such a clear video which saved the day - we had had a week of leaking water and we worried to call for a plumber as we are shielding .My son watched your video and was able to go up and changed the part successfully such a relief ! Thank you again .
No problem Wren.
Very useful and saved me a call out fee...notice the water coming out from the overflow pipe at midnight...search for solution then found you. Thanks a lot man.
Chun Song Lee No problem Chun.
You, Sir, are a STAR! Every tradesman I've ever employed, without exception, has either done a terrible job or tried to rip me off - or both (usually both!). How I wish you were my plumber..... you know what you're doing and obviously not afraid to share it without it costing me a penny! I did exactly as you said and the leak is fixed. The only problem now is the numpty who installed the cistern in the loft has routed the overflow pipe over the top of the tank, which means the tank must be brimming over before any dribbles into the overflow. He probably thought 'This ballcock will last 10 years before it starts to leak, by which time I'll have ripped off enough people to have retired.....' I despair.
The bad tradesmen are out there along with the good.
U saved me €250...10 years after u posted this, thank you very much!
Glad I could help! Never too late. As they say. Plumbing never changes much.
@@dereton33 I might add for my own situation I live in a high limescale area. As a result the fittings were corroded and seized. A huge amount of WD-40 and a decent helping of elbow grease got us moving. All the videos on CZcams made this part look easy 😂
Hello Al, just to say a big thanks for posting this tutorial, had an overflow leak for a few weeks and wasn't looking forward to plumbers fees! anyhow after watching this, went out and brought a new ballcock and valve and fitted it myself today, the old one was submerged under the water (plastic float somehow full of water) a lot easier than i thought it would be to replace and so far all is working well!!
That`s great to hear, saved yourself a few bob.
Al, thanks for great video, I was thinking I had to replace all the lot that is the pipe entering the tank but you showed just refit the new valve to the existing inlet. Saved a lot of time and hey now I'm a plumber! !!! Thanks again. Eric
efoster494 The more plumbers the better. ha ha.
I’m not one for commenting on posts/videos but 👏👏👏 . Moved into a new house - the water hammer when running the shower was awful (a flick of the cold water tap would sometimes fix it). I replaced the header tank float valve assembly and it went away. One month on and Durrrrr. Noise back. Replaced the float valve in the cold water tank and silence has been restored.
This has been really useful, if I hadn't found this video I'd still be trying to remove the valve right now instead of going out to get a new one.
Thanks for showing everyone how to do it.
No problem Ash.
DIY newbie here! Clear instruction here was super helpful and has saved me £85 which I was quoted from a plumber. Also saved us going nuts with the constant overflow dripping noise 24/7!
Glad it helped!
Thank you, replaced mine today (water jetting from the overflow) and only had to make one trip into the loft thanks to your video... As they say knowledge is power, thanks once again.
No problem.
Thank you, finally sorted an overflow that’s been dripping for a while!
I got the part 2 from screwfix for £7 with no problems, but I’m in a hard water area so the old one was incredible scaled up and couldn’t remove it inside the tank, instead I took it off from the outside like in your video - how to renew a tank valve that is overflowing
It was very helpful and useful.
Elizabeth
No problem pleased you sorted it Elizabeth.
Thank you. This may be the first DIY job I have undertaken that went down without any fuss!
No problem.
Thank-you sir, saved me a small fortune on a plumber call out over a bank holiday weekend!
That's great have a beer on me.Al.
As per usual great video with worthwhile information..Both Dereton 33 and Tom Plumb on youtube have greatly helped me with my confidence as a newly qualified plumber and gas engineer...Thanks
jimbob jimbob No problems and good luck with it. Al.
Many thanks for this video, gave me hope - in my house expansion tank was obviously suspended from a crane and the house built round it - seriously thought I was going to have to cut the pipe work to slide the thing out to replace the valve.
You video showing the coupling allowed me to check with phone camera and sure enough there it was - really pain getting step ladder in loft but managed to do the job semi by feel alone.
Overflow stopped but German Shepherd upset - don’t ask .....
Thank you Sir, you are a gentleman
Davy
No problem Davy.
Excellent - you explain things very well and have a great style.
Thank you for sharing your expertise!
No problem.
Great video in a apprentice about to do this today on my own but supervised and my nerves get me but this video has helped me drill it into my head and show myself it's not complicated and can be done by anyone
+Joshua Collingwood good for you. Keep st it you will be fine
This guys has a video for everything!!! I have to say a thank you to him because he's helped me out a good few times. My water tank is constantly trickling, I hear it at night and throughout the day but I can't see any water leaking from the over flow pipes and I don't have a leak anywhere... I don't figure out what's going on.
Change the roof tank valve.
Many thanks for the instructions ...top video for a DIY simpleton like me :-)... got a new type 2 (as shown on video) from Screwfix for less than £8 ... needed to wire brush old valve and spray it with penetrating oil because it is about 40 years old. It was a tight fit scrambling in the loft but eventually got it sorted after following the video. Thanks again pal.
Pete Moxon No problem. Al.
Thanks to this man i have now saved on a plummer and done it my self. Thanks for putting this video on .
Hi Deretan, just done mime, boosted by the simplicity shown in the video and confidence from some of the previous posters who have managed to also do this for themselves.
I replaced the whole thing, going out of the tank into the feeder pipe connecting into it. It took me a few hours as my tank is one with a small hatch and only a limited amount of space to get at the parts. Don't forget the PTFE tape or you will get a dribble coming out. As was tightening up first time round I inadvertently undid a 2" existing 'junction?'. Anyway all's well and good and the job cost the princely sum of £5 !!!!!!
***** Well thats a good £50.00 at least you have saved on calling out a plumber, well done.
My wife has just done this. Took a while to free off the threads as all limescaled up. But she did it. (I can't fit through the loft hatch!) very clear video. Many thanks.
No problem Mark.
Great video - very useful and saved us a call out fee. (And thanks for confirming the fitting size as well!)
Hi Paula, yes those plumbers losing work because of me, are not very happy but I know you are. He he.
Cheers Derek, our valve wasn't overflowing but was going off like a foghorn everytime we had a shower ! Just replaced the whole ballcock valve only £5 from the local plumber.
That`s great.
Another excellent video. Straightforward and easy to follow instructions. Thanks
Glad you enjoyed it
Thanks for this fella. Leaking float valve changed as well as installing a new Ballofix valve to isolate it next time....cheers for the tip.
No problem.
Quality video. i was going to dismantal half the pipe work. Pays to watch a video to save yourself 3 hours work and a flooded loft. Cheers Al
The tank is filling to replace the water that your cistern used when you flushed it. If the tank valve is noisy then replace it.
Thanks for making this video, it's a good feeling getting the job done :)
No problem.
Those covers if you have a round or square plastic tank do just pull off , it`s just that they feel as if they are suctioned on , give em a good pull.
Kind regards
al.
No worries, pleased you managed it ok,
regards,
al.
Thanks, just called into screwfix on the way home and bought the valve shown. Turned the water off swapped them over and no more overflowing :)
PS is the water in that tank going to any taps as I sure hope I am not washing my teeth everyday in that crud ?
If your cold feed is going to the bathroom basin tap then you may be brushing your teeth in it.
Hey Al, just a thought.
You should edit this video to say at the start to turn the water off (for the sake of any smart phone users already in the loft)
Cheers!
Yes a good idea , I always just presume .Regards,Al.
Brilliant piece of advice
No problem I have uploaded the overhaul of the part 1 valve now , it is on my channel
Kind regards,
al.
Thank you for the video . it's very helpful.
Thanx V.Much! I had a problem + the hot water tap, making terrible noises! But your easy Vid. has shown me how to rectify the problem, thus have saved myself £200, having not having to get a Plumber out! Yippee! :) Keep up + the Vids., you've got me hooked.
Thanks Rob, pleased you sorted it OK.
Thank you for making this video as it made the job very easy & all for £4.60
+blackvrs No problem.
Thanks for posting. Very helpful.
Cheers mate, brilliant video. As a hamfisted groundworker I usually avoid anything that can't be solved without a 25 ton machine but following your video I successfully changed the whole ball valve. Took less than ten minutes. Thanks a lot, I'll be trying a lot more fiddly stuff in future.
Splendid video. Clear and precise. Thank you.
Thanks Gerard.
It’s great watching a true tradesmen doing a job and sharing things his learnt - much appreciated.
P B Wright - Handyman
No problem.
Cheers man . Just had to replace mine and this video helped a lot .
No problem
great easy to follow instructions, thanks
Thank you once again for explaining things so clearly
No problem Jan.
Thank you very much for this video saved a few Bob on a plumber
You're welcome!
I thought water would still come out. When the balls not on is it closed by default. As I need to change the isolation valve that's on that same pipe. As its a plastic one and the slot s mashed up so would i need to drain system to swap it. Would water gush out when I take out the plastic push fit valve off?
Very good I like your videos mate
Great vid. Thanks for being a genuine bloke.
No worries
Good man, thank you so much for sharing this!
No problem.
Good video would of struggled without it, just finished replacing my old one no problem.
A Part 1 is very old and can be noisy for sure but its hardly horrible, it's a tried and tested design and they are very reliable. Certainly much more reliable than the more expensive plastic "tat" you find in todays cistern's.
good clear informative videos though
I love your video's. Very informative for a novice like myself. I don't do DIY but I'm going to try this myself as it looks easy enough (famous last words!) LOL :D
Good luck.
Thanks for the video.
Glad I watched this thanks Al. Nice watch BTW
Thanks Paul.
A big thank you for your kind help. I really appreciate your expert knowledge
You are very welcome
Thanks for this. I think i can do mine now
that was really good thanks very much kev.
No probs.
Kind regards,
al.
Ahh I just seen the end of vid that's how you stopped the water lol. I'm guessing I would need to stop the water to change the valve. I'll watch your other vid!
Thanks very much! Managed to do mine today.
No problem.
Thank you man, your a life saver
No problem.
Thanks for sharing this video - it's really useful. Is there any device that can be attached to the spout to reduce the noise it makes when the tank is refilling? Maybe a flexible tube that goes from the spout into the water. If so, is there a technical name for this?
+Paul Dowsett There used to be a plastic tube on them years ago to sort out the noise but now they are illegal, in case water gets sucked back down from the roof tank to a cold tap. EU strikes again.
Good helpful video, you cannot always fit the spout sfter replacing the float valve.
Is marine plywood suitable for a tank lid?
Yes that would be fine.
Another great video 🙌🏼👍 this may be a silly question but is there any way of adjusting the cold water feed flow rate from the water tank to taps (reducing it) via the water tank itself?
Just adjust the gate valve on the feed pipe down to a slower rate.
No probs kevin.
Kind regards,
al.
Hi dere thank you for your simple down to earth steps to what's usually a scary confusing thing, we have a plastic ball valve the arm is plastic like a jointed arm, we are trying to figure out is it the same steps 🤔🙋♀️
Best to remove those completely and replace with a brass part 2 valve.
Thank you.. very clear and informative
No problem.
Hi Dereton, most of these regular household ones usually give a range of a usable float ball as being 'a choice' between 4½, 5 and 6in.
My question is - in what way do these size differences of the actual ball - affect the operation of the mechanism?
Thanks in advance.
The bigger the ball the more pressure is exerted on the valve piston.
Hi mate your videos are very helpful. My header tank is not filling and I have no hot water but cold taps are all fine. Will replacing the ballcock do it? It's not going up and down as it should.
+chefsuprise . Yes renewing the valve will fix it.
Thanks for sharing this I have changed ours with your help :) The copper pipe that bent towards the top of tank I have knocked should that be above or below water level please ?
It should be above.
Regards,
Al.
Thats great :) Many thanks
Great video will be fitting it tonight so will let you know how it goes
Good luck with it Keith.
As mentioned on another video firstly familiarise yourself with matters before venturing into the loft. Go through everything and in the process you won't leave anything behind spanners or whatever when you venture into the loft. , and if your going to keep the old float and reuse then clean it up first, remove the limescale on it, especially important for heavy limescale areas. Mike
Thanks Mike.
very useful video. Many thanks
+Darren Huntley . No problem.
Thank you. Great instructions.
No problem Gerard.
Thanks very much! Very useful and i managed it all by myself :-D
Well done Andrew .
Kind regards,
al.
Thank you for this!!
Nina Gonzalez No problem . Al.
Great advice on how to replace the valve, but you really need to replace the whole tank! Those black spots are biofilm. The gel coat on the inside of your GRP tank has started to fail, and each spot contains microbes, legionella or other, which could give you problems. If you clean and disinfect the tank then you're good for a short while, but the spots will come back, maybe in a few years, maybe in a few months.
Got rid of this old tank went for a combi.
I've two cold water tanks in the loft each 70 gallons and a cold water feed to the ball cock valve that has to be turned off via the house mains stop cock in the kitchen. I've now fitted a lever full bore 15mm isolation valve just outside of the tank to isolate the ball valve. When replacing a ball cock you must switch water off to isolate the ball valve water because it'sfull mains pressure.
Hi Al,
I'm looking to do this in my loft, as it looks exactly the same as yours! When it comes to turning the water off, all I have is the stopcock out by my water meter in the pavement outside. Will this be sufficient? Or would it be worth turning a cold tap on after turning off the supply, just to drain some of the water away from the supply to the loft tank?
Thanks in advance!
Oli Barton That stopcock will be fine. Opening the down stairs tap will remove any water left in the pipe, so it is a good idea. Al.
Thank you, this helped me out when I was a bit stuck.
Hi man wonder could you help the smaller tank in the Attic I think it's the hot water tank for the heating. It was constantly over flowing out of the over pipe outside. So i put a new ballcock on the tank yet after a few hours it stills over flow outside . No leaks from the new ballcock . How can it still fill up it's driving me nuts no matter what I do it still overflows. Any ideas why Thanks
It is a pinhole in the inner coil of the hot water tank. Only way of fixing it is to renew the tank.
Great video as always.
I brought a replacement but doesn’t seem to fit into the existing as in vid - just kept turning .. is there a reason for this ? Had to put the old one back on. Stupid question but as it’s gravity fed system are these High pressure valves correct ones ?
Sorry another one - I swear I watched a vid which you mentioned how to install the isolator valve for the header tank - or did I make that one up. Thanks in advance
I did make a video for fitting an isolation valve it is on my channel. High pressure valves are the correct ones for roof tanks. The threads are sometimes different, so do not fit, in which case you will have to change the complete valve.
thank you very much
i just saved lot of money
No problem
Quick question Al, when you unscrewed the arm, it seemed as though you were going in the direction to tighten it up and when you put the new one on, it seemed as you were unscrewing it? Are they opposite threads? cheers
No it just looks that way it is a right hand thread.
Good video, simple for women who have no man to do things. And I love the watch..,,😀
That`s great thanks for watching. Watch has long gone now, shame.
Superb video 👌🌟.
Thank you! Cheers!
Thanks, I was trying to undo the old one and it was going around and around and... anyhow, this showed me the error of my ways!
That`s great.
Great video thanks
N problem.
Great video, just one thought, what size ballvavle fitting do i need ?, are they all the same
will it be 1/2 or 3/4inch
Hi martyn, it will be standard 1/2 inch. They are all the same.
dereton33 Thanks for the helpful video. I was wondering about the thread size too. Mine has a slow drip. There are some advertised as 1/2" or 3/4". Possibly best I check before going to plumber merchant ?
So very well explained
Glad it was helpful!
Very helpfull information thanks.
Very welcome
Great video. I'm getting lots of noise from the pipes. I have a combo boiler and hot water tank. Does hot water tank need ball valve changed?
You can get a quiet fill valve.
@@dereton33 any link to where to get it from
Hi, I am trying to remove an old domestic cold water storage tank valve. Very worried as it is leaking bad and covered in limescale also a galvanised rusty tank, I would really appreciate any advice. Thank you.
Renew the tank. Never thought any of those old galvanised tanks were still going. Most have all rusted through by now.
Best replace video. Thank you sir
So nice of you
Thanks for your help bend the brass arm on plumbing tank and i think the problem is fixed
Great Mark.
