My hot water tank has started making a odd noise, it's not the normal
poppy sound from tank deposits. The best description would be a half
second drum roil about every 10 seconds. ( almost like a animal
scratching itself in the wall) I have drained the water out of the
system thinking it might be some kind of air harmer, Drained some of
the water out of tank, the only way I have got it to stop is to shut
the water to tank off and blow some water out of PRV. The tank is
about 7 years old 50Gal, GE, self cleaning. It's pretty much non stop
so any suggestion would be a help. Thanks

Do you have an anti-siphon valve? How about an expansion tank in your
system? You may need one or you may need the one you have made functional
again.
