That said, I finally got around to relocating my pressure tank to my crawlspace. I don't know if it was absolutely necessary (again, I'm not a plumber) but I thought that getting it out of the elements was a good idea. It's also cooler down there so it won't be subjected to the high (90+ degree) heat and temperature swings. Also, I won't have to drain and move it in the winter.
I used the following:
- 3/4" slip x 1/2" FPT PVC elbows
- 3/4 in. Schedule 40 PVC Tee
- 3/4 in. x 3/4 in. x 1/2 in. PVC Sch. 40 S x S x Female Pipe Thread Reducing Tee
- 3/4 in. PVC Sch. 40 Female S x FPT Adapter
- 1/2-Inch Pressure Relief Valve
- 1/2 in. Brass Push-to-Connect x Male Pipe Thread Adapter
- 1/2 in. Brass 1/4 Turn MPT x MHT No-Kink Hose Bibb
- 3/4 in. PVC Sch. 40 Pipe
pump that I have shuts off at 55 psi. In theory the pump should never cause enough pressure to make the tank fail. I didn't want to take any chances. I got a spring loaded pressure relief valve that opens at 75 psi. The hose connection allows me to drain the pressure tank, and the other connect attaches to the existing PEX pipe I recently ran through my crawlspace.
