A necessary compliment for pumps

Used before the pump for a dedicated filter circuit for my 1500 gallon boiler To filter out the hard water calcium carbonate precipitate that forms are the water temperature increases.

Plug not included

This strainer does not include a plug. Make sure to order a 3/8" plug to go with it.

Gets the Job Done, Did not leak!

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

Good Basic Inexpensive

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...

Insulating the pipe will help with the issue, a great option for this is our Insul-Lock insulation made by K-Flex: http://www.pexsupply.com/K-Flex-B247000

No, it does not. The 3/4" model has 3/8" FNPT threads on the drain.

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.

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.

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

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.

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.

My contractor did not have problems removing the plug and replacing it with a pressure gauge.

Stephen: 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, Brad

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

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. Gary

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.

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
