I went down to my basement last Friday and found the carpet soaked and 1/4" of
standing water in the furnace/water heater closet. There were no drips from the
ceiling or walls so I assumed that the water heater - which is at least 15 years
old - blew out. But the tank was full and it was still serving up hot water and
the leaking had apparantly stopped?!? The pressure relief is vented outside so
that's not it. What could have happened? The only possible explaination I could
come up with is that the tank developed a leak that somehow sealed itself with
sediment. Is that possible? Anyone ever see such a thing?
Rare, but it could be the water heater.
Pressure could build high due to thermal expansion
(especially if you're on city water), but not high enuf
to trip relief.
15 yrs is pushing your luck. I would think about
At the very least, get a "flood alarm". They're only
a few bucks.
Dunno, but they do that sometimes when pressure changes
greatly. In fact, you might want to put a pressure
gauge on this one if you're on city water. Watch for
pressure creep during heater firing or even late at night.
