was very disappointed that the 2 inch gasket didn't fit like it should have,it did not sit in the grove flush. Had to heat it with a heat gun to stretch gasket to fit. It also was a struggle getting the splitnut for the heater to grab correctly to tighten

Easy glue in and slip as well as heaterside seal. However water started leaking at gate slide shaft immediately after sliding open position. Applied lube to shaft and after a few open close movement stopped leaking.

I cut off the defective part and replaced it with this gate valve and no more leak!!! This one-piece should prevent joint leakage.

My old one was leaking and needed replacing. When I say ""old"", I mean really old. There was no exact replacement but there was a very helpful guy just a phone call away who told me exactly what I could do to make it work. And it did work! Thank you, helpful guy!

Valve did not work at all. The threads on the valve were not the same as the split nut on the heater. I tried 5 different split nuts and none of them worked right. The only way to get them to thread at all was to loosen the screws on the split nut and in the end there was no way to properly tighten the nut so as not to leak. I do not know why this happened because the valve was exactly the same as the one that I removed and it threaded on and off just fine.
