Used a Viega Manablock when I replumbed my 1955 Craftsman about 12 years ago. Loved the product then and would reuse it now in a heart beat.
Couple of notes:
Agree that the Manablock connections are a bit frail. I used 1" copper as the supply in with a PRV, pressure gauge tap, and a pair of 1/4 turns to isolate PRV/gauge/Manablock. The whole apparatus was a bit heavy and I was worried the Manablock wouldn't take the stress on install. But I got it mounted and now that its installed there is nothing to worry about.
I used the cold pass thru on the bottom of the Manablock to feed my tankless using 3/4" copper, and returned on 3/4" copper to the top on hot side. I used the bottom hot tap as a return to a recirculation loop to just after the tankless unit. This allowed me to keep the main hot line and the Manablock hot at all times.
All hot taps for low flow fixtures (shower heads (not tubs), kitchen/bathroom sinks, and dishwasher were plummed with 3/8" pex. This kept the displacement between the manablock and the fixture low and with the recirc resulted in near instant hot water on all fixtures.
You dont have to flush mount the Manablock on the wall. In my case I installed it in a 2×6 wall cavity and drilled holes in the studs to match the Manablock tap locations and fed my pex lines thru each hole. I then covered the whole setup with an access door in my garage to hide the plumbing. Looks super clean. I dont think this would make sense in your application but just wanted your viewers to know there are other options.
PEX pipe installation is a perfect DIY project. I remodeled my home in 2007-2008 and did the entire plumb from the manifold to each distribution point in the home while we were in the framing stage just before insulation and drywall. My then-16 year-old nephew was the "monkey" who did the climbing and running pipe overhead. Easy-peasy! 4 sinks (2 kitchen, 2 bathroom), 2 bathtubs, 1 shower, 1 clothes washer == all 7 hot & cold, 1 dishwasher = hot, 2 glass fillers, 1 ice machine, and 1 pot filler == all cold. Total of 8 hot water lines, 11 cold water lines (all in 1/2") -- installed in about 3 hours and connected to a Manabloc 24 port manifold using compression fittings instead of crimps as shown in this video.
Best of all . . . with a Manabloc manifold, you can eliminate ALL of the shut-off valves at the terminus of each line -- those pesky cheap pot metal valves that have a habit of corroding in the open position and then the handle breaks when trying to force them shut when you have a leaky faucet or need to repair/replace a toilet . . . turning an otherwise simple job into a nightmare. And you don't have to shut off the water to the whole house when you need to repair fixtures without those valves (tubs and showers).
Saved a ton of money by not having to hire a plumber to do more than run new PVC mainline supply from the meter to the home (with a separate stub for landscape irrigation supply), copper from the inlet/pressure valve at the house to the whole-house water filter, and to the manifold and tankless water heater, and new drain lines for the kitchen sinks, a tub and shower in the master bath, and the washer. Bought most everything at the time on eBay, including a ratcheting crimp tool and bands, barb fittings, and a stapler that fastened hold-downs over the pipe every 16-24" as recommended. Pipe nipples out of the wall were purchased locally at my local Ferguson, The Home Depot, or Lowe's. Not a single problem with the installation since then.
He is really building an organized home for his family! He has all pipe well labelled. No guessing what is what. He did great advanced planning. He did not scrimp on the size of this utility room, either. Plenty of room to get around, see everything. I get jealous that he is building this, not me. LOL. I'll bet inspectors LOVE to inspect his work. It is like getting a day off, without having to use up any vacation time.
Very impressive water organization! Love how everything is all labeled. Looking forward to what you’ll have up your sleeve next time!
Looks great. Love the updates and how you address comments and concerns. So nice to see such attention to detail and thoughtful planning, especially on a residential project.
Love the way you show all parts so that we can go find them for ourselves. Makes it easier to find. The step by step process helps as well. You make me feel guilty for sitting and watching and not out doing.
I'm likely never going to remodel or build a house but I love watching these kinds of videos. Well, maybe I would go for a prefabricated.
That’s impressive! Nice clean install! That’s the way things should be done!
Good looking water system job, as I love the manifold systems myself. Thanks for your comment on my previous post. In construction, everything is evolving with better products and techniques to improve our homes, but at a cost. Just like the manifold system-- not cheap, but efficient. Keep up the good work!
I don't know anything about setting up a water system in a home, but watching you work is like poetry in motion! It's so educational and interesting, thanks for sharing! 😊👍💕💕💕
Getting better every week! Thanks for sharing. Keep up the great work.
Nothing more satisfying than seeing a clean pex system installed. So many so-called plumbers out there think that just because pex is easy to run in a house that it doesn't matter what it looks like. That's the problem with pex. It's too easy so installers don't care, they just throw it in and leave. Any joe schmoe off the street will be able to immediately notice a nice and neat pex job versus and an ugly pex job, remember that. You don't want a builder/homeowner/fellow tradesmen to be like 'wow, that pex looks like my grandma put it in, either rip it out and re-do it with some pride or you aren't getting paid'.
Thanks! This is a situation where my desire for perfection pays off!
Mechanical room is looking great. I love the home run system. I like the panel job also! I’d strip the sheathing in the trough and install a ground bar in it. That way all you have to run is your hots and neutrals to the panel. If the inspectors allows it
Thank you so much for taking the time to go to a fixture and turn the water on. So many videos on here of ppl showing install only.
For me I'd rather put the in coming of hot water from the heater same color of the tube but it's still okay very impressive I learned a lot from your video I'm always waiting for the next new... thanks for sharing your your knowledge to us it improved ours
.more power
Great planning on the rough-in side makes for nice connections at the final. Nice work.
Looks awesome can't wait to see it finished keep it up brother
Excellent video. Ive seen a bunch of them covering installation and yours is the best. Clean and organized! My ocd triggered over the blue pex from the heater to the manifold but no big. lol
Thanks for the comment!
thanks, great video - most helpful new thing for me was how you planed the 2X4s to 1" to help provide support near the manibloc connections
Your videos are so great to look at, hope to see when you tell us about how big your family is and how many rooms you are building,
Excellent job, Paul !!! Thank you for sharing !!!
Thanks for watching!
Very professional and neat looking job.
I like that you are using a water heater for each level of the house, which will cut down on your cold water evacuation time you have with these types of systems.
Hi you are the best teacher.you explain everything with detail . Thanks for your help .Good lucky to your professional life
Thank you!
Hi from the Netherlands.
Very often technical spaces are designed too small, which means that you have to work with many right-angle bends, which creates a lot of noise in the installation. Very clever to plan enough space for this in the design of the building. Looks sleek!

At 10' of 3/4" black pipe you have about 600,000 Btu's available @ 11"WC at the manifold. Instead of the expense of all the regulators you would have to buy going up in pressure, plus having high pressure gas lines running through your house I would change the manifold to 1" and 1" to the outside with a 1" regulator. At the manifold you will have around 1,150,000 Btu's available for distribution.
Fascinating Mr Marshall. Many thanks.
Excellent presentation, Paul !!!
Just came across this page haven't watched any of your other videos yet this one has convinced me I can do the plumbing in my new home. I have done regular PVC and CPVC remodel homes many times just this is a new home and really want the manifold system wasn't sure if I had the knowledge to do PEX in such. Beautiful clean install exactly what I'm hoping to accomplish thank you for all the good details.
Hey welcome! Glad you found this useful, the Mad County Build is the name of this home and the playlist has it in chronological order if there’s other stuff you’re curious about!
@@MrPostFrame I went to add you to my subscriber list and it turns out :-) you were already there for something else definitely will going back and look more thank you very much
Amazing work every time you present your videos...
Nice system! We've got most of our lines ran in our house but there is still so much more to do. We used copper for our water supply but will use pex for our in floor heating. I still need to look at some more videos on how to install the in floor heating system. Hopefully you will do a video on in floor heating.
Very clean. Appreciate the video
Very neat job. Thank you for sharing.
Great video! It seems like just yesterday you were roughing in the underground! :)
This is absolutely perfect awesome job
Thanks!
I'm a plumber and I do the same thing when doing gas pipe with no problems!
That is a work of art.👍😜👍
great system, about to put a manifold in.
Nice new school plumbing method without treading welding glueing no more headache
BEAUTIFUL JOB‼️.
I like the water manifold!
Excellent well thought out design and execution. I’ve question though, would you not be better certainly from a visual point of view using the red hose coming from the boiler to the manifold as that’s hot water? 👍👌🏻
Looks good and clean, would have run hot water supply line under then up to top of manifold, that way supply lines don't cross at top.
My ocd is loving this 🤪😎
Fantastic job
The German in me is proud of ya..Nice work.
You already have an Isolation valve at the bottom of the tankless heater for the hot water side of the manifold.
When your done with all the plumbing you should paint that room a white color or gray.
That looks clean. They stopped making the compression fitting unfortunately. It had a perfectly uniform look. Good work welcome to Madison county neighbor.
Thanks
Running “touchdowns” for water pipe is the way to go
Let’s see a 50 psi test on the system! sorry, it’s just the engineer in me😂 looks awesome, starting on my pole barn house this week. I plan on copying this type of system!
Hey buddy, good work as always... What brand of pex clamps are those? Real clean!
Looks great
Thanks!
Nice work. You make that complex manifold look easy. Don’t worry, I know it isn’t.
Very nice work.
Do you have to worry about freezing in the Winter where you are?
I ask because I like to drop my water DOWNWARD where it concludes at a ' lowest ' point enabling drainage of the house as efficiently and quickly as possible.
Nice work
I love the idea of a manifold for my water supplies, never thought about everything being a home run. My concern is more on health and safety, how long can a line stay stagnate with no use and the water doesn't have any issues? I always saw merit in running a main loop that everything branches off of with this loop works to pressure balance and can have a pump on it as well. Saw it once on TOH in early 2000s. Love your mech room! If I could I would dedicate a huge about of square footage of my future build to it as well, if I can get away with it. I would have to dead bolt it to keep my wife from wanting to store stuff in it!
Do you get a commission if I order thru amazon. Definitely getting one of these. Great videos. Thanks for your channel. Building a container home so your videos have been super helpful.
Hey Paul love your videos. I’m actually re watching them now.
I’m new to the pex thing but curious, are these home runs all 1/2 inch or 3/4 to their destination?
Thanks.
Hi! Very Nice! Could you tell me how you determined what size supply adapters you needed? I assume since you didn't use the bottom supply connection that you didn't have a water softener which I gather would have connected to the bottom supply line.
What are you using for pipe?
I'm looking at alpha PEX-A from pex guy
Thanks, by the way, your work speaks for it self
I have this set up it's very convenient
awesome
is that thermal controller what I am thinking it is on the side of the instant water heater? I have them put on my previous one and the present one to bypass the internal choke on the limit of hot water, of course, one has to be careful if have kids not to scold themselves.
Dan
Good job!,,
Thanks!
I thought the pex pipe had to have a 6-8” straight run off the manifold before a bend or there’s too much stress on the manifold?
Are you running a hot return to get the hot water there faster to the fixtures fast
It looked like you used blue monster teflon, the only difference between their natural gas/propane tape is indeed the thickness.
Хорошая работа друг
eline sağlık çok mükemmel olmuş
Thank you!
Could you put a line on the lowest part of the hot and colds on the manifold to use as a system drain ? Im going to redo a seasonal place that requires a complete system drain annually and want to use this system to accomplish that. Really I just don't want to spend hours clearing all those lines of water.
+Marshall Remodel Is there a major difference between the home run style over the trunk and line style plumbing with regards to wait time for hot water at a fixture?
how much insulation are there between the hot and the cold lines? Weird to bring them so close together in proximity. Wonder if its better to have separate manifolds for each line?
It's basically two separate manifold tubes encased in a plastic box, hot & cold do not touch each other.
How long did it take you to redo all that when the inspector failed you for being way too close to the electric junction box? (At 11:23)
Why didn't you use red tubing coming out of the tankless hot water heater going to the distribution manifold? Not trying to be petty; but, you did an excellent job on everything else, so, just wondering why you used cold water blue piping and not red piping coming out of the tankless heater.
Just didn’t have 3/4” red on hand and needed to get it going ASAP. I’ll switch it out eventually because it bothers me too.
Good morning from St John Parish, Louisiana 27 Oct 20.
how much would this system cost if were to ask as an upgrade on new home build?
With PEX I only trust type A UPONOR
Might be a dumb question, but why is the line coming from the hot water tank to the manifold hot side not the red/orange color? Having that as blue would appear to be a cold water line. Clue me in.
Just didn’t have any 3/4 red on hand. I know I will probably change it out but I needed to get water going ASAP.
no whole house water filters or water softener?
Why is this not in your plumbing video playlist?
Oversite thank you for saying something! Just added it
There's some really nice work happening in your utility room. But why didn't you do something to finish off the plywood first, even a quick coat of white paint would have made such a difference setting off the work and making the room so much brighter? And is the water heater feed line really 30" from the side of the electrical panel? From the camera angles used it looks much closer than that.
I think it’s 30 inches total side to side. 15 inches on either side.
Dave Hicinbothem
Kinda like a toilet. If I can take a dump an electrician should be able to service a panel.
Is the tubing different for the manifold system? I have seen it should be pex B. Is this half inch coming out of the manabloc?
It’s 1/2” pex. No difference in pipe when using a manifold system.
Why run the pex supply pipes in the slab rather than through the walls? Isn’t that going to be a nightmare if you have issues down the road?
What kinda problems will he have? There is two crimps on each line that you can see and if he wants to have a sink on an outside wall he would have to put it in the slap as well.
Your plumbing is not a maintenance intensive system. Install it properly and it will outlast you.
thinking of getting that manifold but i don't trust plastic products. especially a valve requiring a special tool
Does it make sense to run the water lines (pec tubing) inside pvc pipe all the way to the room your runing it to
I mean under concrete floor
Not to be overly critical, but if you have several appliances (like dishwasher, washing machine, sinks, bathtubs, showers, toilets) on at the same time, won't you lose pressure in them with this manifold system? If you have two people taking showers in the morning and the dishwasher is on, and the outside hose bib is on and you have someone washing their hands at a sink, will you even have any pressure at the two showers?
Normally, a dedicated 1/2" or 5/8" homerun line is run directly from the main (in your case a 1" main if I remember right) to each bathroom. If you are going a long way, you use the 5/8", but 1/2" should be sufficient for up to 250-300 FT. I don't know because I have not used a manifold like this, but I am wondering if it has big enough lines to keep pressure throughout the house.Again, I am just trying to help, I am not being over critical.
Probably I am just concerned about nothing and you have it covered.
Hi there.dou you think this would work with pex a?
Can I use uponor pex pipe with this maniblock
Where did you get your clamps? next to the manabloc
I bought mine at Menards. If you don't have access to a Menards, home depot, or a lowes I have some in our Amazon store. Amazon.com/shop/marshallremodel
you realize the blue pex turns the water cold and the red pex makes it hot right?
I thought the connections should only be hand tightened
when you put in your storm cellar i thought great, why would you just put wood over it instead of prefab concrete slab, you could have poured another foot of concrete over it. you could have even used it as a safe room with a steel door.
damn ... torx screws for pex clamps.. impressive.. lmao
First!
Ainda dizem que os americanos sao melhores do que os outros a trabalhar, este ocupa um muro inteiro pra passar meia dûzia de tubos... ainda bem que nao tem os tubos para rega piscina etc...se nao ia ocupar os quatro muros...iiiiiillllll
Can you use sharkbite fittings on these?
You can get it in push fittings (similar to shark bite) or crimp style. Supply House is where we got this. Also in our Amazon Store.
The Teflon tape for water 💦 will break down with the gas. The yellow or blue depends on brands is designed for gas only so it can handle the chemicals involved.
The hot water Line was installed as blue.... oops!!!!
Second lol
Get a water bug under that manifold.
