I live in a 2 story townhouse and I am experiencing 2 problems which may be related-in the downstairs bathroom, after your flush, a loud whistle begins and keeps going for about 10 minutes-it gets softer as time progresses until finally stoping. Does anybody know what is causing this and can I fix it? In the upstairs shower when you first turn on the hot and cold water a loud banging noise begins and when it does the hot water decreases-when you increase the hot water pressure with the faucet knob the noise stops and the hot water returns. I would really like to know what the noises are-do I have air in the line and if so can I eliminate it? Any info would be appreciated because sometimes the noises are so loud you would think something is going to blow. Thanks

Hi:cjdodson

A couple of my of the wall suggestions. Hope they help you.

Regarding the toilet:
#1
Try adjusting the incoming water volume using the water shut off valve located underneath the bowl.

#2
Try this with the water flow valve located inside the tank too. All else fails, replace the tank flow valve with a new replacement.

Regarding the shower:
#1
If the shower has a single lever to make the adjustment, the cartridge may need to be replaced.

#2
If the hot and cold water each has it's own faucet, try replacing the valve washers.

Other then these suggestions, since I am NOT a plummer, I cannot think of anything else you can try/do yourself. You may need to contact a plummer.

Hopefully, a real plummer will post other possibilities for you to try.

Good Luck,
TomBartco
