Is there a "shock absorber" (first time I've seen it called that)
near the sink? A 50' run's an awful long ways to not have one
there. But, since it did work and doesn't now, you're probably
on the right track unless that valve is just no good.

Providing your
thermostat/element is working correctly, if a new Relief

doesnt do the trick, id get rid of the water heater. You can
get a
2.5 gallon Water Heater for $119 in Home DePot.

I can't see any flaw in the heater itself that would be
causing this
- it's 100% the popoff valve, and the only thing the heater
could be
doing is overheating - which it can't, with the power off.
I've
never encountered overtemp water, either, so I don't think
that's
happening.

Someone elsewhere suggested that it might be water hammer,
exaggerated by the long piping run, causing brief
overpressure. I'm
going to do the drain- the-house thing to empty the hammer
shock
absorbers and see.
