Remove Water Heater Plug
Last fall I was unable to get the water heater plug out to winterize the system. I ended up just blowing out all the lines with compressed air but could still hear water bubbling in the water heater t...

Could it be possible that someone installed a metal plug in drain hole instead of the proper nylon plug? Without knowing what type of water heater it is we only have conjecture.
Another thing is the heating of the plug to ease removal. Steel tank is okay but with an aluminum tank, not a good idea.
Finally, Teflon tape is a sealant, it is not an insulator. I'm of new at this game, I've only been RVing since 1998 and I have only been in the construction trades since 1954 and a General Contractor since 1980 and I have never seen or heard of a pipe plug or threaded connection that did not cut through the Teflon tape and make metal to metal contact. If it were true that it is an insulator, we wouldn't need dielectric couplings.
Not trying to criticize, just trying to clear up a couple of wives tales.
