On-line advice says residential gas water heaters last about 8 to 12 years. I have lived here for 12 years and my neighbor says my water heater was 5 to 10 years old when I bought the house. So the water heater may be 20 years old. It still works fine but I wonder if I should get it replaced while I have time to find a good plumber rather than waiting for it to fail and have to use the first available plumber? Thanks for any advice, especially from plumbers.

> Do NOT use thread tape on any gasketed fitting.

I didn't know this. I always figured the extra seal is a bonus. Granted, I'm no plumber and have little knowledge of the field. I know the necessary drop for pipes to flow and that's about it. Outside that all I know is shit rolls downhill, paydays on Friday, and don't bite your fingernails.

Extra is bad, in this case.

Ugh, I bite my fingernails all the time.

Taping gasketed fittings can lead to leaks.
