Hi- My new shower is now making the loudest high trumpet type of noise I have ever heard. Due to low hot water pressure we have to turn the hot-cold handle all the way to hot and the pressure handle all the way on just to get enough hot water to have a decent shower.
Now, when you do this, as soon as the hot water arrives at the shower valve it starts making this horrendous noise. Did not make it the first two months, but it does now. If you turn the handles down, you might be able to reduce the noise or maybe get it to stop, but then your shower is either luke warm or with barely enough pressure to get soap out of your hair.
The plumber says the low pressure is due to a section old pipe between the bathroom & the water heater. (the sink doesn't have much pressure either) He has refused to come out saying that it must be a defective valve and is not his fault. I am not convinced. How would you go about solving this? It is a brand new Porcher valve, with controls for both pressure and temperature. It does have the anti-scald feature as well. Is this something he could fix if he came out?
