PEX Loop Fitting Assemblies Options
PEX-AL-PEX Loop Fitting Assemblies Options
Optional Installation Accessories:

Loop End Cap
Actuators
  • MA-ACT: Thermal Actuator for Rifeng Manifolds
    If you want to use your manifold to heat multiple zones, you can purchase return side actuators that work along side thermostats. The actuators act as zone valves to allow you to use one manifold to control the temperature in different rooms independently.
Supply/Return Adapter Options

Note: Bleeder valves that come equipped with Rifeng Manifolds are 1" BSP Thread (manifold inlet) x 3/4" BSP Thread (outlet). If your application requires you to connect to a garden hose, you will need to purchase a Mr. PEX Manifold End Cap w/ Swivel Fill-Drain Valve separately which is 1" BSP x 3/4" Hose Thread

              Shocked at how fast I received my manifold and when I opened the box
              I couldn't believe how well built it was for the price I paid. I took pictures and shared them at work with another guy who is putting in some radiant floor heat.

                          I separated(detached) the bottom manifold and installed the top back bank first. Then I installed the front lower manifold, that way I did not have to bend tubes to get to the back manifold making cutting and installation easier. The reason for blue and red pex: each ajacent red/blue pair are in parallel with reverse flow in each pair to even out heat distribution.

                          When tightening the EK20 nuts, I was not sure of the torque. Air pressure was set at 30psi (observe guage on top manifold); soapy water helped make sure there were no leaks ( you have to get those nuts really tight).

                          And finally, you may notice the 2x6 on the wall that the maifold is attached to, I made a 3 sided box of 3/4" plywood down to the floor that attaches to the 2x6 to protect the pex!(not in the pictures)

                              The outlet size is 1" female pipe thread …….its the same size on a 2 port all the way to a 10 port.

                              I believe the 10-ports for the loops are threaded for EK20 fittings (a European trade size, I believe) but the I.D. of the port is fairly large and list for use with up to 5/8" tube.
                              The inlet and outlet mains are much larger - 1"+ ID, I think ... each 10-port manifold (supply and return)has an EK size fitting at the end, which is then fitted to a small brass body with temperature gauge/ball valve shut-off which then terminates in a 1" female NPT thread. The other end of the 10-port manifold also has an EK thread fitting spedcialized for filling and draining the system
                              But maybe that is just how I purchased mine - with the temp gauges and valves included.
                              These certainly do make it nice for filling / draining and watching water temp in and out of the manifold.

                            Hello, I will be installing 3 of these units for hydronic floor heating, each loop will be about 200 to 250 linear feet 2000-2500 total feet. One on each floor, basement, main floor and second floor, creating 3 zones. What size circulator pump is recommended with these manifolds, I would use 3 seperate pumps, one for each manifold. I was considering the Taco 0015-MSF2-IFC, would this pump be enough, or would a larger pump be required?

                              depending on gmp flow rate you are trying to achieve usually around 3gpm
                              your head loss would be between 4 and 5 ft plus you feeder lines if 3/4 in
                              is 3.73 per 100 ft. so as long as your pump can pump the gpm at your head
                              loss you should be fine. I usually use Grundfos pumps UPS15-58FC three
                              speed pumps for this application and have had great results.

                              Circulator pump sizing depends on the flow rate and head pressure of the area that is controlled by the circulator pump. See the link below for specific sizing information.

                              The material is the only difference. Many people prefer the Rifeng manifolds because of the stainless steel metal, the price, and the inclusion of shut-off valves and flow meters.

                              A:

                              Typically Stainless steel is harder material, and can be more problematic to seal the threaded joints, but it is more tolerant of aggressive water chemistry. Brass is softer, and thus easier to seal threads on, but can be a problem where water has sulfur, or other problems.
                              I use the Stainless Rifeng manifolds, as they are priced right, and if you use teflon tape, and pipe thread sealant both on the threaded connections, they are no problem. The o-ring connections on the loop connections is no problem, but be careful when sliding them up into the manifold, as it needs to be straight, and put a little water on them to lubricate the o-ring, or it can tear the o-ring and you will have to replace it.
                              Hope that helps.

                              A:

                              In my humble opinion, both are excellent choices, however, depending on the
                              other components in your system, stainless steel may be the better option
                              since it is not affected by electrolysis problems that sometimes occur with
                              the electrical currents that sometimes are created within a system.
                              Stainless is a "harder" material than brass.
                              Thus, if cost is not a factor of concern, I would prefer Stainless Steel
                              over brass but it may be more of personal preference than it might be of
                              any thing of substance.

                              A:

                              I believe the main difference is chemical resistance, i.e. stainless steel (SS) products are more resistant to corrosion than similar products made of brass. SS while very strong is not as ductile and is therefore more likely to shear or crack under high mechanical stress. Brass is not as strong by weight and so is generally reinforced with thicker walls (heavier.)
                              That being said, different manufacturers may use different grades (series) of SS to make a product for the same purpose. The 316 series and 630 series are more resistant to corrosion than the 400 series and so different grades might be used for the different parts in a single valve (stem, ball, etc.). So manuafacturer and reputation may be a concern.
                              For the 10-loop manifold pictured below from Rifeng, (1/2" I am guessing) I will say that it has worked well in the very limited time I have been using it (2 weeks) and installation was very straightforward.
                              I should note that the flow gages might work well if mounted right side up (and perhaps sideways?) but not well upside down (PEX runs going up)..
                              I have both brass (Mr. PEX) and SS manifolds (Rifeng) in my setup - originally I had a Mr. PEX 2-port 3/4" brass manifold sending water to Rifeng 10-port 1/2" and 7-port 1/2" SS as "remote" manifolds in the 2 zones of my house. However, having one large manifold fed through one port of another manifold (even if it was a 3/4") caused flow to be too restricted, especially by the internal parts of the flow gauges (along with the valve on the return side) so I removed the 3/4" brass manifold from that setup.
                              The Rifeng 1/2" manifolds did not come packed very well by Rifeng and each manifold set had one of two thermometers broken (PEX Supply was very good they suggested I return one manifold set with both broken thermometers and then sent a replacement.) They are decent manifolds - very light for their size (because of the SS) but parts seem but some of the parts seem a bit cheap or "chincy" as they say, for example the broken thermometers and half of one handle on a ball valve just broke off in my hand trying to spin it. The other end of the manifold does have a nice drain valve which spins freely 360' open or closed which was nice and it could be removed to mount on a gauge for pressure testing. The end by the ball valve is 1 1/4" MPT while other fittings are a different thread with O-rings.. These fittings did provide good tight seals.
                              Comparatively, the Mr. PEX 2-port 3/4" brass manifold seemed like it had more quality (maybe that is just my feeling being that it was made in Italy as opposed to China) but the thermometer and handle thing did not help. The Mr. Pex manifold being brass is pretty heavy,the threads all seem very high quality as did the valves and thermometers. It came with one end of each manifold piece (supply and return) capped on one end with a special T for a drain and either a screw-bleed vent or an auto-air vent. The auto-air vent I acutally think is a bit cheap. The last thing I did not like was that the special T-fitting on the end must have been glued down (Loc-Tite?) after being wrenched on really well because that thing was NOT coming off, which makes mounting in different configuarations a bit more of a thought process. But this also led me to believe that the whole unit was really built well because a lesser unit might have been damaged by the stress of trying to disconnect the T from the manifold.
                              Overall the Rifeng manifold is great, especially for its size, light weight and number of ports, but consider how hard you will be playing with it. If you tend to play rough, or the unit might be subjected to some bumps in your basement, then you may want to think about the Mr. PEX units, just know they are not as easily configuredas the Rifengs.
