Uponor a2701002 manifold

Tubalcain

Hello!!

I just found a really nice brand new in the box Uponor A2701002 10 port manifold at a surplus store for very very cheap. I understand this manifold is primarily for radiant heating however I wanted ask if anyone knows if I can use this beautiful manifold as just a regular hot and cold water system manifold for my home? I don't have any plans to install radiant heating but would like to replace all the old water lines in my house with pex tubing. Anyone familiar with this type of manifold please advise. Thank you!!

I don't see why you couldn't do that. But…check the max pressure rating. A heating manifold would typically run at a much lower pressure (14-20 psi) than a typical house domestic water system pressure which is usually rated to something like70-80 psi max. Here is a Viega Manabloc link for potable water. It has designated hot and cold hook-ups.

No, I wouldn’t try and use it with potable water. The water passages are narrower and the minerals and O2 in potable water will foul it up quickly.

This one?

Pressure is fine, any high flow faucets? The ports are 1.1 Cv.

The manifold would be fine in theory but you will need to find lead free adapters to your pipe size and type in an R20 thread size

Thank you hot_rod… Yes that's the one I have. It's a huge 10 port manifold and from what I understand this this retails for over $900.00. I got it for $65.00. No I do not have any high flow faucets un the house. So since the pressure is fine you're saying it's ok to use?

the only issue I see is the brass nuts used to connect the tube to the manifold are not NSF61 listed. This is a low lead law for anything that touched potable water.

I though maybe they may have used stainless connections.

If this were to be inspected, that may come up.

Looking at the fitting there is not a lot of the brass that touches the actual water, as the test standard is based on a weighted average of the entire assembly.

So it may pass the low lead test, if the manufacturer were to pay the fee to have it tested and listed.
