Hello, a question for the specialists. I can’t seem to unscrew the hot water angle valve in my bathroom to replace it – it feels hollow at one point. It seems like the plastic thread is damaged. I already asked a plumbing supply store, showing them a picture of my wall installation, but they just shrugged and said it’s probably not a standard installation. The plastic fitting seems to be the issue. Can someone explain what is behind the plastic fitting? The problem is, I think since I tried to turn it about 4 weeks ago, the hot water pressure throughout the entire apartment (8-family building) has been lower. The main water valve is fully open. So far, there is no sign of moisture, and the neighbors downstairs haven’t complained yet.

Thanks for the tips and advice.

Rental or Ownership.

For rental apartments, inform the landlord so they can send someone. For owned properties, arrange for someone yourself.

Water damage can be costly.

Hello

Did you disconnect the faucet hose and then try to unscrew the valve from the wall? Even though you turned it counterclockwise, the valve didn’t come loose?

As a plumber, I would have shut off the water immediately and started looking for the cause.
There might already be some damage inside the wall.

If I were you, to prevent extensive damage, I would order a professional FIRST THING tomorrow morning.

Hello,

I am the homeowner. I turned off the main valve in the bathroom, disconnected the faucet hoses, and turned the angle valve to the left. It seemed to unscrew slightly, but after about 10 full turns in total, nothing else happened. I then stopped to avoid further damaging the thread, in case that was the problem.

I am simply curious why the professional with over 15 years of experience—who shares the same workshop with me at the company—was not familiar with this type of installation. Is it something unusual? And what is behind the plastic fitting? Is it a coupling that connects the water pipe to the valve? An extension? Also, could anything inside be affected by turning the valve? I did not have to apply excessive force.

Thank you for your help.
