What is this for?

[Andrew Cox]

This house was built 10 years ago, and the original owner was a plumber - did the house plumbing himself.
Have you ever seen this? It's a plumbing distribution panel. Hot and Cold lines come in, and it branches off to all the fixtures in the house, with all the fixture shutoffs at this one spot.
I was pretty impressed...not that it takes much!

[Stephen W. Stanczyk]

A very common PEX distribution panel. I see these a lot during draw inspections. Builders either use them in all their homes, or in none of them depending on which supplier they use.

[Marc D. Shunk]

That's a Manabloc. An older one, from the looks of it. That's quickly becoming the standard way to pipe up a new home in my area. Pretty slick. Really no pressure drop at the fixtures when someone flushes a toilet, etc.

[Bob Elliott]

That would depend on the supply.
Anyway Andrew , how big was that house with so many fixtures.
I notice there are eight using cold only so I imagine the outside water supply to the lawn is there also.
Still seems like alot for a studio apartment.

That is so when those polybutylene water lines break, you can isolate them.

Ha.. Here in Chicago we do not have that problem with our wonderful galvinized.

[Michael Larson]

In case you missed the intent of Mr. Kelly's comedic remarks, did you notice any markings on the pipe such as PB2110?

Run, that is poly....

[Andrew Cox]

No, could not see markings at all. It is black piping to this panel, but not from it. And it's 3688 Sq Ft, 5BR/ 4 baths. This is to be a vacation home.
The supply to this panel is buried in the wall, could only see 1-2" at this end. And yes, I was amazed at the pressure available at all fixtures.
How should I report this - as poly piping?

Should have said PB2110 earlier.

See this thread for some verbage on the issue

[Bob Elliott]

Since we really do not see pex or poly that blew right over my head.

[Jeffrey R. Pope]

Yep, PB, which (as we all know) is no good.

The manifold is a common install in new construction, typically seen with PEX or PE.

[Andrew Cox]

I've not seen it either, but one other time. Thanks for all the help.

reminds me of zoned heat
