A solid if not beautiful casting. Installed with no issues or leaks. Filter mesh was solidly installed and should stay in place.

Comments about Watts 1" 77SI Cast Iron Wye Strainer (Threaded):

I used this on water to water heat pump on the ground loop coming in to the heat pump. Much cheaper than equivalent brass strainer. I have an air eliminator so iron is OK, but with the cold water going through it there is lots of sweating and already some rust on the outside. I'll have to wrap it well with pipe insulation...

  • Q:

    Can you buy smaller mesh screens for it. I want to remove sediment from my boiler water as it is plugging up my mixing valve.
    Asked on 11/9/2013 by Just fix it the newbie from Canada

    • A:

      To add to the previous comment:
      The main purpose of the strainer is to be in the main flow. If you install it on the side-stream, it is basically useless, because not all of the particles are going to be restrained in the mesh. The bottom line is, if you install the strainer, make sure you clean it on the regular basis. Otherwise don't bother, because you can cause a lot of damage to the boiler, if the mesh clogs and flow is significantly reduced.
      A lot of times in more delicate systems two manometers are installed before and after the strainer in order to monitor the flow. If the pressure on the downstream side (after the strainer) drops by +-10%, it is about time to clean the mesh. Again monitor and service your system on the regular basis.
      The plug size is 3/8" for the 1" strainer, and 1/2" for 1-1/4" strainer.

      A:

      Yes, you can put a screen in to filter out particulates. I use my Y
      in a water fall. A screen keeps the ports on the water fall open. The
      smakker the screen, the more impurities you will collect. ( these may
      have to be removed later by taking the Y apart. ) You can also predict
      that if the screen gets really small flow diminishes his may make you
      wish your had not messed with it. So here's a way to get the size
      correct. Take mason Jar an collected some watering it. If you see no
      particulates in check in the morning with a bigger sample ( gallon
      jug). When you can identify the size of the parch clues you can buy a
      filter to control them. Go down to home depot and ask them for screen
      to habdkle the particles you have seen. They can probably set you uo
      with a screen you can just wad up and shove in the Y to control
      particulate. Make sure it is big enough to make water flow through it
      but noy occlue the flow altoether. lohn

      A:

      I am unaware of any alternate strainers. But here is a caution: don't
      install a strainer in the main supply or return of the boiler - install
      it in a side-stream, so if the strainer plugs, it won't cut off the flow
      through the boiler.

  • Q:

    I bought the 2" version of the Iron Wye Strainer. I cannot remove the screen retainer plug using 18" pipe wrenches. I want to make sure I can get it off before installing it to the system. It looks like the plug was installed into the fitting body without thread compound and then painted over. Any suggestions appreciated. Yes, I have thought about using bigger wrenches but then I'd have to buy them just for this.

      Have you tried using a cheater bar? I find a 2 foot piece of pipe over an
      18" pipe wrench is usually enough leverage to open anything I have.
      Good Luck,

      Hit it with a 24" and it should break loose, I don't think I had too much trouble with mine.  Hope this helps

      A:

      Heat the plug up using a propane or other torch, to soften up the
      paint. Then wire brush the plug threads and apply a penetrating fluid
      such as Liquid Wrench or Thrust (WD40 doesn't usually work for this,)
      and let set for 10-15 minutes. Then try your wrenches. If it does
      not turn, reheat the plug (The penetrating fluid is flammable so be
      sure your working outside or over a
      noncombustible floor)then try your wrenches.
      I hope this helps. If your piping a lot of 2" you should be using
      24" wrenches.

      I recall buying one of these, but did not have to use it.  That said, the plug
      should come out.  Perhaps if he has access to a substantial vise to clamp it in
      (by the hex surface on the body) and a short length of pipe to slip over the
      wrench handle (cheater), he could get enough torque on it to get it out.

      Try using a cheater pipe to put over the handles of your pipe wrenches which will give you more leverage.

      A:

      Hi: Its cast iron and super strong so you will not break it. Put it
      in a big bench top vice and use a cheater bar ( Like a piece of black
      or galvanized pipe ) 24-36 inches long that fits over the end of your
      pipe wrench. That should allow you to break it free. John
