I just finished installing a replacement water heater. All of the connections are dry except the dielectric into the cold inlet. I have tried tape, dope, and replacing the dielectric with a brass fitting. I am still getting a very small leak from the fitting. When I take the fittings off, the threads look like they have been smashed down. No longer clean sharp threads.
o Could the cold water inlet be out of round?
o Is there a pipe dope that actually hardens to some extent that will fill in the voids and not be displaced when I re-apply pressure?
