I have just replaced the valves in my shower taps and now when I open the hot tap I get a very loud, high-pitched scream?
Once you replace a valve it can take up to 2 weeks for them to settle in. As the rubber is quite tough it needs a little while to get worn in and become soft. If the issue has not ceased within a month we recommend that you use our PlumbConnect Plumbers Registry to locate a licensed plumber.
