Description
–
The Stainless-steel Manifold Assembly with flow meter comes fully assembled
and ready for installation. Use the included flow meters located on the supply
manifold to balance the loops across the manifold. The return manifold comes
equipped with isolation valves for easy loop isolation. For multiple zoning on the
manifold, the black caps are removed and replaced with Uponor Thermal
Actuators. The manifold body ends have R32 union connections and the loop
outlets have R20 male threads. The included manifold supply and return ball
valves come with an R32 x 1" NPT connection.

works great
All the goodies that come with the manifold - flow meters, flow adjusters (manual,but can be automated later), drain valves, thermometers, isolation valves work great. Every piece of this additional equipment makes life so much easier. Thermometers seems to be precise (as opposed to others I bought separately for 20 bucks each). Drain valves swivel. It takes no physical effort to open or close drain valves. I wonder how it can be so easy to move and still being sealed well.
My installation has passed 50 PSI air pressure test with no issues.
Now, I got two boxes, only one had the manual and stickers included. Manual is important. I don't know where to download one. Fortunately, in the second box there was a manual. If you get a box with no manual, I think you can use the manual for the brass manifold from Uponor.

Good Manifold-Mostly
I am not a HVAC guy but installed our hydronic system using runtal radiators and this manifold. I started 2 years ago with a Mr.Pex manifold that leaked badly within a year, so I went this this unit as a replacement. Today I noticed that there was a leak at the union. Unfortunately, the union is not repairable and had to RMA the unit. The pressure is up around 18 PSI and when the PSI drops lower the leak seems to go away, but replacing either way.

I would buy this product again
These manifolds are simply the best. You want quality? This is it. Solid stainless steel. And love the flow meters. Our company has installed hundreds of these and never had any issues.

A better product than the competitor brand.
Two loop radiant floor system. Easy to balance.
It would be even better if it could be install 180 opposite direction.

Very nice manifold
Installing and purging the loops were very easy with these. They look great and the flow meters easy to adjust and read. I'll for sure use these again in the future.

Nice manifold
The flow meters are crucial to balance out loops of different lengths. The bracket was bent during shipping but was easily bent back

You can't beat a stainless steel manifold
We do upper end installs. You can't beat a stainless manifold for pop. Add flow gauges, thermometers and actuators and you have a very nice, easy to use integrated piece.
