We had our water shut off at our lakehouse for the winter. My husband blew out all the pipes. We just recently turned it all back on and when we flush the toilet it makes a terrible noise at the pump like huge pockets of air are coming out. But we ran the faucets everywhere for quite awhile so not sure it’s air bubbles?

What pump? Water supply pump? Sewage pump?

I guess I shouldn’t call it a pump the equipment in the tank.

does it sound like a high pitch whistle?

No it sounds like air forcing up through the tank. We flushed it about 15 times and ran other faucets to be sure we got all air out.

Could it take awhile to get all air out?



Edited 1 times.

It is NOT air. Any air would be evacuated IMMEDIATELY as soon as you opened a faucet. it does not "hang around" for hours waiting to flow out.

Could this be the fill valve a faulty ballcock causing a lot of whistling, take a look inside the toilet tank when this is whistling and see if you can pull on the fill valve which is the portion would stops the water flow into the toilet. Sometimes that will go bad and cause a low loud Whistling noise
