              This is the mechanical piece to the radiant system and is highly overlooked. I had replaced 12 of these in our home. The old ones were not responsive (test by pushing down on them and they should spring back pretty fast) or stuck (usually in the closed position). They were easy to replace. Use a 6 point socket to remove and have a 12 point socket handy also if one is hard to remove or strips. I just replaced a friends radiant valves the other day. He had 3 of his stuck closed. While you are there, inspect the end caps of the manifold and replace the end cap seals if they are leaking.

              I need these valves for maintenance of heating zones in an assisted living facility. We probably have 35 zones in the facility and I usually need to replace one or two valves every year. These valves are excellent replacement units which install easily and work very well.

              Replacing Manifold Valves

              I live in an area where the water is very hard with a lot of lime in it. It tends to coat these valves until they don't work and then they will cause the valve actuators to leak. I replaced all of them this year, 12 valves, and it only took about 20 minutes and is really easy. Make sure you adjust the actuator valves after replacing them. The service is excellent, Thanks!

              I use these valves to replace worn parts in a hot water heating system in a senior citizens assisted living facility. I know I can count on them to work everytime

              I have been putting off changing some leaking valves.

              Pressure was down to 0 and circulation was noisy.

              Put in 6 new valves and pressurized the system.

              Wham-mo!! Perfect! all back to factory specs.

              Easily replace manifold valves

              Comments about Manifold Valve Replacement For 1-1/4" Brass Manifold:

              If you have hard water then more than likely your valves are coated with calcium deposits. The valve I replaced was leaking and ruined the motor valve actuator. If the rest of the valves look like this one (they probably do!) I will be replacing them all. I know some zones are not heating properly so I will replace them first. This is an easy thing to do, just make sure you drain the manifold first.

                  Unfortunately this valve is discontinued without replacement. The return manifold would have to be replaced.

                Q:

                Do I have to drain the manifold first to replace the valve?

                And to refill the manifold after I am done?

                Is the 1-1/4" the only size for the radiant heat system?

                It is for a underfloor radiant heat.

                Thanks.

                  When I have replaced one of these valves I had to first shut the water
                  to the floor system off, and then drain the manifold (it should have a
                  drain on the end). There is not a lot of water in there, but it will
                  make a mess. Replace the valve, open the water back up and the system
                  will fill itself. I don't know if there are other sizes, mine is also

                  A:

                  Installations can vary, but my experience two years ago in the house I rented was that you have to drain enough water to avoid a huge mess and avoid getting the valve electronics wet when you quickly swap the valve. My system had enough shut-off valves for the seven zones that I could isolate it reasonably well and avoid gravity draining water from the tubes and letting a lot of air get into the tubes and manifold. I assume you have a place to drain from so you can do a decent job of getting the air out of that zone once you've reassembled. One of the automatic valves I replaced had deteriorated so the valve head was missing, therefore it flowed constantly when the pump was running. I was unable to find the missing piece, but it didn't seem to restrict the flow, so it wasn't an issue. I also had a problem with the manifold gaskets leaking, so watch for that. I fixed the problems myself, because the cheap owner couldn't get anyone to fix it. He had two guys out over a couple of days who did less and charged $1,500! The heat was great, but the system wasn't maintained well. Good luck.

                  A:

                  Yes, the manifold has to be drained. Once the valve has been replaced you will need to refill the system.
                  Keep a shop vac handy for any water coming out after you pull the old valve out. Usually the manifold is lower than the boiler, so some water may still be in the system.
                  Good luck.

                  A:

                  Most Radiant systems are open loop so make sure the incoming water is shut off to the system before removing the old valve. Usually very little water will come out if any at all during the valve replacement. It is recommended to put a small amount of plumbers grease on the O-ring before installation of the new valve. After the new valve is installed, turn the water back on and unsure there are no leaks.
                  The 1-1/4" is a standard size for the valve.
