Good Value for the money
from Princeton, NJ
I have used manifolds from Uponor and Embassy and thought I would give these a chance. They are good, but the many union fittings make it difficult to get a water tight seal. The temperature gages are in the way of being able to get a wrench on one of the union fitting. With rubber O rings and nylon type gaskets, I am concerned about long term durability.
Bottom Line No, I would not recommend this to a friend
Solid units, work well
from Salt Lake City, Utah
I purchased 4 of these (3, 5, 7, & 8 loops) and installed them myself. I am not a plumber, but managed to get them in without too much difficulty. Do be aware that they are large (much bigger then the old INFLOOR units I replaced), but that they seem to be about the same size as other brands with similar function. They also seem to be less expensive due to the stainless steel bodies rather than brass.The units are very solid in construction, and offer excellent bleed / flush ports, and also valves to isolate the unit completely. The also have thermo-wells which is a nice touch, but i noticed that the body of one of mine was loose on the stem so I would not be too dependent upon their accuracy.Do be sure to check the size of your PEX hydronic heat lines (mine are 3.8" so I had to buy those fittings - the default that come with them are 1/2". Also, if you are using 3/8" PEX loops, my plumber (who I had check my work), suggested not to throttle the flow valves back at all as the flow rates are so low that any impedance could cause improper heating. He also pointed out that the manifolds themselves will distribute the flow well due to their large volume so throttling should not be necessary anyway.You should also be sure to use a 1" male brass fitting on each of the inlets and outlets (actually the valve body) as I was unable to get seals with copper fittings (maybe just me - again I am not a plumber, but the brass units worked perfectly first time). You should also be aware that the valve end of the manifold is a bit fiddly when it comes to leak stoppage as you have a sequence of a rubber seal, nylon seal and pipe thread all in just a few inches - but I did get them all to seal and I am sure better plumbers than I will do it without worry. You will need two large crescent wrenches (or a crescent and a pipe wrench) to tighten up this bit if you care about the final position of the valve handle and thermo-well (tough to explain - you will see what I mean when you do it yourself).I did have one fault on the 7 loop unit, and that was a very slow leak around the seal on the flowmeter. PEX Supply replaced the unit without question and the replacement works fine.Overall- good product, I only market the unit down due to the one leaking flow meter (which required removing the whole unit from a very tight opening in a wall cavity in my home), and the unreliable thermo-well.
Great product for the money, all i use

Good quality stainless steel manifold. Easy to install and use. Very serviceable
I have standarized on these manifolds
By Randy the Hydronics guy
from Chapel Hill, NC
Given that these flowmeter equipped manifolds have a maximum per-circuit limitation of 1/2gpm, they are an excellent value and look great! My only wish is that they made the same thing with bigger flowmeters so I could use them as Zone controlers on my main hydronic control boards.
