how far off the floor for PEX manifolds?
Is there a preferred height to mount PEX manifolds (for potable water, not heating)?
The current layout is 3 6-port manifolds (2 cold, one hot). I will layer them like in the attached sketch. 1/2″ PEX on the runs, 3/4″ between the manifolds and to the wh. The manifolds are located in the utility room of a single story house. The individual runs will run through the crawlspace.
I’d like to keep the top manifold under 5′ if possible. Is there a preferred height from the floor to start the manifolds and a preferred distance between them? If not, I will start the top one just under 5′ and just space the next two wherever a gradual curve of the 3/4″ tubing takes me.

Think I would look at ease of access in the future, too close to the floor and stuff gets set in front of them. Personaly I go with waist high for the lowest one.
Remember the manifolds can also be installed verticaly if works out better for you.
Put them wherever you like.
Why all the redundant ball valves, are there no stops at the fixtures?
I thought that you do not need stop valves at the fixtures if you have manifold with shut offs?
Correct you don't, except in commercial work.
But if the faucet breaks does one really want to run back to some room & figure out what valve shuts off what fixture?
Ahhh, true, you make a good point. Thanks for the info.Alan S
I have a manibloc and dont have shutoff valves.
If I were to do it all over again, I might put shutoffs at the toilets, but no where else.
I have no issue with going to the bloc to cut the line.

To make a short story long: I bought a house once that about two days after I closed, the washing machine cold water line started to leak. After spending a couple hours, I discovered that there were NO shutoffs in the house. I ended up having a plumber come out and use his 4-5' long tool to shut it off at the meter. Apparently, the house used to have a main water shut off and a hot water heater shut off, but when the previous owner put in a bigger water heater (ie taller), they cut out both and forgot to put them back in. And then when they decided to "upgrade" the downstream plumbing system to PB, they decided to save a few $$ by not putting shut offs at the fixtures. For me it came under the category of "live and learn".
But anyway, ever since then I've gone overkill on shut offs. So yes, I will have the manifold shutoff plus the fixture shutoff on the other end. jt8
