 Water Heater dielectric leaking
Author: greekguy7 (IL)

I got a 50 gallon water heater that's 10 years old.

It looks like its now leaking a little by the dielectric union on the hot side. Should I try to snug it up a bit... or should I unscrew it, replace the rubber washer, put some tape/dope on the threads and reinstall?

Thank you as always, and hope everyone has a great 2017!!

if it is the union joint leaking, take it apart, clean it, (it may or may not need a new rubber gasket) then lube it well with grease and snug it tight.

I was adding some heat-proof grease to my order at the supply house, Had a Licensed Plumber ask me "what do you use that stuff for".I put it on everything.

i started my career working at the boston navy yard in 1963..
i went thru a 4 year apprentice program there.
anyway, when working on the boats were greased everything that didn't stand still.
the lives of the crew depended our work being done perfectly. no corners cut and 2 inspections. one civilian and one military.
funny thing is we NEVER used levels. the boat may have a 5 degree port list or it may be moving if the sea was rough. so, i learned to measure off the bulkhead or the deck and pipe accordingly.
ahhh, the good old days..
