I recently found that a joint on the pipe coming out of my cistern/holding tank was leaking. Every once in awhile the pipes come loose because of the vibrations of the pump. It was a huge mess but we got it fixed for now. It got me wondering if its possible to use PEX for that application in the future.
The pipe coming out of the cistern is 3/4". The old setup was it had a 3/4 to 1" elbow and then a 1" elbow that led to a 1" pipe that went to a coupling that went from 1" to 1 1/2" or 2" (I didn't measure-- think it was the former).
Would I be able to replace the run coming out of the cistern with PEX and then somehow put it on a coupling/adapter that would expand the size? (Is it even allowed to expand the size the way it was done?) The current setup is very awkward.
I think the guy who fixed it made the it all 3/4" up to the adapter that went to 1 1/2". It just needs to expand to hook to the pump. I think the line that comes out of the pump is 3/4", so I'm not sure why its set up that way-- unless it should be the same size coming out of the cistern.
Right now the line coming out of the cistern has a ton of joints from past repairs and its just ugly.
If it can be done, how would you recommend doing it? Would PEX be a bad idea? It would be inside a small building and I can wrap it in something to protect if if need be.
Here is a general sketch of the setup-- it does not show the convoluted run of the pipe out of the pump to the pressure tank or other things in the pump-house.
