underground piping for natural gas
Posted by Jerry on October 07, 2002 at 15:51:43:
I need some advice on what type of pipe and adapters to use to replace a 50' run of 1" iron pipe supplying natural gas to my pool/spa heater. The existing pipe has a slow leak and is capped off right now. The pipe is buried. I am planning on digging a trench alongside the existing pipe and replacing it with some type of plastic pipe. Which type/ or brand of pipe is best in terms of durability and economy? How do I adapter from 1" iron pipe thread to the plastic pipe? I plan on pumping compressed air into the pipe to leak check. What PSA is required (past pressure regulator)?
