I bought a water softner from Lowes. "INstall kit" has a few fittings that snap into place, no problem there. But the final connections on the softner is a 1" plastic pipe. 1 for in and 1 for out. My house has the flexible water pipe 3/4". I got a metal bell reducer to convert it down to 3/4", then some NPT fittings, and finally an NPT to push-fit connector adapters. everything seems water tight EXCEPT, the bell reducer leaks on the connection to the plastic water softner pipe. I am using teflon tape on every joint. I have pulled that connection off, retaped, and tightened, still leaks. I tried 1 layer of tape, and 3 layers of tape, still dripps. What am I doing wrong?? I may pull it off again and try some pipe dope... I don't know. Any suggestions are greatly appreciated!
