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.

Gate Valve for the heater.

Spa Depot is my go to spot for repair. I recently had some weather and rodent damage to my HT and it was out of commission for some time. This summer I started repairs and was able to get all the parts needed for a full rework of valves, pumps and fittings. It is now back in shape and ready for use
