After 8 years of trouble free service, our rheem pvs50 water heater makes a hum/squeal when water is being used. Resetting the power breaker stops the noise until water is used again.


It sounds like the heating elements are getting coated with calcium/lime/other chemicals that are found in your water. This would indicate that the elements are approaching the end of their life and may be getting ready to burn out. Consider getting some new elements soon and scheduling a time to install them.

Pressure relief valve intermittent noise


check your water pressure and then make sure it is not to high or all the problems you have had were not the answer. it is a pressure /temperature valve not just . temp.

I have a Bradford White water heater (model# MITW50L6LN10) that started making noise yesterday. Tonight when the family got home we started a bath for the kids and surprise surprise no hot water left in...


Probably cheaper to fix existing water heater.
The problem might be the power vent, or the power vent might be short cycling because the gas control valve is bad, or vacuum switch has gone bad.
Call Bradford White and get their recommendation for your specific model.

Bradford White is very good brand of water heater
Rheem, Richmond, GE are good.
I prefer the AO Smith, American, State, Reliance, Craftmaster. Kenmore, Whirlpool brand since air intake screen is located on bottom of unit and can be inspected and cleaned without removing burner.

sediment build up is usually causes thumping and noises from tank. it needs flushed out. models, where the heat source is beneath the tank. The burner heats the water under the sediment, leading to a build of steam. The steam finally escapes as bubbles, which can cause the sounds.

New Rheem Fury Guardian System 50 gal water heater model 42V50-40F. Loud low humming or drone sound when in operation. What can this be?


Hi,
Is the noise when the water is running or when the burner is running???

If it is just the water then the noise often is the flow checks inside the tubes going to and from the heater...

If it is the burner, then the noise could be the gas going through the gas valve...a bit of moisture or dirt can sometimes cause noises...usulally will correct its self after a bit of time...no worry...

poping crackling sounds and such are common with mineral builsup in the bottom of the heater....
Flush the heater and get the dirt out....

sizzling noises sometimes happen from condensation dripping onto the burner....gain not a problem...

sometimes the gas properties will cause the gas to make noises when going through the gas orifice into the burner... usually this is air or a LP air mixture known as "citigas" that will burn like natural gas but really isn't and it will make noises such as your are describing...again no problem...

Ultimately the noise you hear is not a problem but can be irritaing if the heater is where you can hear it easily...

Feel free to comment back if you have any more questions...

Started humming periodically when using hot water and tankis filling up with cold water


Usually when a tank is making noise, it means the tank needs to be cleaned out or flushed.
I wrote a page with diagrams showing how to clean out a tank, and how to flush the tank.
Page shows gas and electric water heaters.
See if this helps:

Sounds like a squirrel inside water heater


Check your thremostat setting if it is set to highest position it may be causing some of the noise over heating the water and making the noise. And you can put an insulated jacket on it to maybe help with sound.
