    I've heard water lines buzz, creak, moan and bang ---

    I don't believe this is a case of water hammer nor the TPR making noise unless you can actually see some water dribbling out of the end of the safety exit.

    Cycle it and see if the noise goes away.....


    Like someone said - it could be a loose faucet seat

    .... although modern faucets have those Teflon gaskets and they don't make a noise at all.

    A low-frequency screeching noise (more like a moan) can be (usually is, actually) a restriction somewhere in the circuit that creates the noise when it is used.

    If it's your kitchen sink only - or it includes other hot water circuits - these have to be isolated and established to get a decent diagnosis.

    Does your house have a "backflow preventer"?

    I believe there's a backflow preventer in the dielectric nipples as well.

    Could be leaking backwards!

    Wife was taking a shower - so I took a look at the water heater -

    I could hear a faint noise -

    I partially closed the ball valve and got a screeching sound from the valve - then I close it all the way and got a screeching sound from the shower!:devildance:

    I open and close it a few times - it appears the noise is coming from this ball valve -

    I will find a short piece of tube - so I can put one end on the valve and one to my ear - and try and confirm it is the source of the noise.

    Not sure how a ball valve can make such a noise - maybe it is partially plugged with some deposit -

    It is in a really crummy spot behind the vent pipe way in the back top of the closet - which has a few inches of empty space on each side.

    It would be easy to change if the water heater was not in the way - so unless the noise becomes a screaming banshee it will have to wait until the heater needs replacing.

    That was my first thought - it seemed to be mostly at the one faucet - but last night it was making the noise while my wife was showering.

    I don't think so -

    But yesterday the pressure seemed a little low. Back to normal now -

    The fresh air vent tube is just a big flexible tube - it really should have a screen on it - mine doesn't.

    Are there any antisiphon hose bibs on outside walls , make sure hoses are off and bib valve is closed. . Is there any valve in the system upstream from your heater causing some minor flow restriction. My first choice would be an outside hose bib turned on and the hose end shut off. The hose will act as pressure resevoir and bleed bad pressure/volume when you turn hot water on. Can sound like anywhere in house. Erie noises!

    I don't think I have a water regulator - if I do I don't know where it is -

    I removed both of them last summer - they both started leaking within a few weeks of each other.

    Both of them make a screaming noise if the hose was on and you ran water inside the house -

    It was sort of a - you left the hose on again alarm.

    Not that I know about - except on the outside hose bibs - anti siphon things.
