Update – FAIL Don’t Buy – This did not ream out a big enough hole for a pipe to go in, so it is basically useless.
While trying to replace the pump and motor on my hot tub I broke the PVC pipe at the valve. The big problem is the male part of the valve pipe was still inside the 2″ pipe that contains the safety suction sensor. A replacement is not available locally and if I figured it out correctly ordering it online was in the $75 range. This part of the plumbing was still good except for the broke off pipe glued in it. I asked Google for a way to salvage this coupling and came up with something called the Socket Saver. It basically cuts out the pipe in the socket so you can re-use it.
Normally I would just buy a replacement pipe fitting, but in some cases a replacement isn’t easily available or would require cutting out a lot of other plumbing. In those cases the Socket Saver may be just what you need. You do need a different one for each size pipe and the 2″ one I’m using does require a 1/2″ drill. It appears to have worked, but I will have to reserve my final judgement until after it has been glued up in the hot tub for a while. My only concern is the inside is a bit rough, but since PVC pipe is joined using a solvent that chemically melts the pipe together I think it will be OK.
