Don't get me started on bio-plumbing issues. I'm 75 and have too much to contribute on that subject.
As to the issues pertinent to the thread: Thanks, Frodo, for the valve tap suggestion. I gave it a few taps - not really very hard - and have had zero leaks since then.
Problem solved. Magic.
Diehard, Problem seemed to be periodic releases.
Thanks, all, for your input.
 
Excellent!
I'll have to remember that tapping method as the first attempt fix.
But I have to admit, I am a bit surprised that it was periodic releases. But totally understandable non-the-less.

Re: bio-plumbing...Well I'm 78 so we can compare notes.
 
It can also be caused by a bad thermostat. The lower thermostat on the WH in my house was latching intermittently, and the temperature was sky rocketing.

Since I have a tempering valve to control the actual temperature to the house, I was missing the rise in temperature. And, would occasionally see some water in the pan.

I thought the water tank was starting to leak, so I bought a new one. When I went to install it, i found the lower thermostat latched, and the TPV was weeping.

Bought new t-stats, and fixed the problem. New tank is still in the box in the basement. I figured that with the old tank being fifteen ears old, it will go, sooner than later. I should install the new one this winter when things are slow at work.
