  • 3/4" Full Port Brass Isolator Uni-Flange Ball Valve w/ Integral Spring Check

    Q:

    I currently have 4 zones, each with a pump. If I use one of these at each pump outlet I won't need the flow check valves that I currently have in each of the the loop lines? Is that correct?

      A:

      I think it may depend on how the total system is set up. And will all pumps be operated all the time? Or will they be switched on and off? The pumps work best as pushers not as pullers or in suction. I would need to see the total circuit and the components involved to give a more definite answer. Adding the check valves is nice insurance to be sure flow in the proper direction.

      A:

      yes, that is correct.  You can also buy pumps that have flow checks in them as well.

      Yes that is correct put each valve on the supply of pump and you no longer need the check in the pipe.

      A:

      I am not a HVAC professional. Just a determined DIYer who does a lot of research first.
      The answer may depend on whether or not you are using a primary-secondary loop or just branches off a main line.
      I rebuilt my entire heating distribution system last year using a primary-secondary loop instead of the branched system previously employed. I, too, have 4 pumps (though each one serves multiple zones to individual rooms via zone valves). But the principle is the same.
      My research indicated that one needed two check valves: one between the primary loop and the pump (to prevent reverse flow when the pump was off and an adjacent pump was activated) and the other on the end of the secondary just before it rejoined the primary loop (to prevent convective flow of hot water into the secondary loop when the pump was not running).
      I installed the Isolator Uni-Flange Ball Valve with Integral Spring Check on the supply side of the pump and either a swing check valve or a spring check valve (when a vertical mount was required) just before the secondary loop rejoined the primary. I wasn't sure that the second check valve was really necessary but I can feel a big difference in the surface temperature on the pipes on either side of the second check valve so it does prevent convective flow. (My piping was 1-1/4". If you are using 3/4" piping, convection flow may not be as much of a concern.) The two check valves do what they are supposed to do for me. As they say, your mileage may vary.

      A:

      That is correct. The 52403 flanges contain a check valve, eliminating any need for in-line or in-circulator check valves.

  • 1" Full Port Brass Isolator Uni-Flange Ball Valve w/ Integral Spring Check

    Q:

    Is this unit compatible with the Grundfos Type UP 15-42F pump?
    Does it require an additional O Ring?
    Can this unit be used before and after the pump to facilitate pump replacement? Is there another model device which would accomplish this better?
    Asked on 1/22/2011 by Dave from Minnesota

    1 answer

    • CUSTOMER CARE

      A:

      Yes, you can use this item with the UP15-42F. You will use the flange gaskets that came with the pump.
