Replaced an old water heater with a new 40 gal. gas water heater. Used new water pipe port adaptors (3/4 npt to 3/4 copper)in the tank ports. After cleaning the threads I applied teflon tape to the threads and tightened the adaptors tight. After heating the water heater up to temperature (130 deg) I have a very, very small leak coming through the tank port threads (both hot and cold). What is my problem ?? I am a fairly experienced do it yourselfer.
Hello and welcome to the forums. Your problem is easy to fix. The adapters coming off the HWH are not tight enough. You will have to cut the pipes, retighten the adapters with a large adjustable wrench, and install (2) CxC slip couplings and resolder. Use PIPE DOPE on the male threads only. It's possible you miswrapped your teflon tape. When you use dope, you can't go wrong.
