The Tank › replaced water heater, still leaking from pipe outside

Synopsis of this adventure over the last six months:
Water heater is 7 years old.
About 6 months ago, it started leaking out of the “outside pipe” after one of us took a bath.
Changed the T&P valve 3 different times over the last year- it would stop leaking for a few days and then start up again.
Replaced the entire water heater Monday.
STILL LEAKING AFTER WE TAKE A BATH.
What is going on?! I’ve read up on expansion tanks, and have been told by 3 different plumbers that I don’t need one (which is why we bought a brand new water heater). What is the fix? Any ideas?
Oh, and there is ZERO water in the pan in the attic. The only water is coming from this pipe (pictured).
Edit: The pic shows very little water, but the pic was taken at the very beginning. It drips for about 20 minutes.October 18, 2017 at 12:25 pm #23904Randy SchuylerKeymaster
If it’s thermal expansion — and it probably is — you can easily test for it. Using the link on the left side of the Tank topics index, go to Tanklets and click on Temperature/Pressure Relief Valves.
There are really only two possibilities: bad T&P or thermal expansion. It’s unlikely it’s the first since you replaced that several times and have a new heater. It’s unfortunate that somebody got you to buy a new tank to solve such a simple issue.
