I replaced a water heater about a year ago with a Whirlpool.
Sometimes, but not always, I can hear faint splash and sizzle noises
coming from it, like a drop of water hitting something hot every few
seconds. It doesn't persist long. THe unit works very well, and
there's no indication of external leakage.
Is this normal, or is something amiss?
Thanks a heap,
then forget about it, but since its still under warranty call the
manufacturer and ask.
noise is hard to pin down, some folks are very sensitive, others
seemingly cant hear the exact same noise.
only be concerned if a leak can do bad damage, like if tanks in a
finshed game room
You didn't say if it was gas or electric, but I'll tell you my story
I had a gas water heater that sprung a pin-hole leak right near the
top of the flue tube. The leak was not a drip, but a "mist" that shot
from the unit whenever it was under pressure. When the burner was on,
the mist would get caught in the rising flue gases, hit the inverted
funnel on the flue pipe and condense, dripping back down onto the top
of the unit. I can't recall if it sizzled, in fact I don't even recall
what caught my attention and made me investigate the problem. It was
actually pretty interesting. If I turned the burner off, no drip. As
soon as I would turn it back on, water would start dripping off the
Perhaps you have a similiar situation?
It's gas. The sizzle seems to be coming from down low on the unit,
near the flame. No sign of any water or steam or mist. I live in
northern CA and it's been rainey and cool, condensation is a real
I'll keep an eye on it and check back.
If it's leaking down inside the flue tube, I don't think you'd be able
to see it unless you pulled the flue and looked straight down into the
tube with a flashlight. It could be dripping down onto the hot burner
or something that the pilot light is keeping warm. Just a thought...
True...maybe that's where his sizzling is coming from - a leak inside
the tube above the deflector.
A leak below the deflector might never be found, unless the unit was
allowed to cool to a point where the water didn't evaporate,
eventually pooling enough to appear on the floor.
