ShowerValve is a referral service, not a contractor. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands, and valve work opening a wall is often a permitted alteration — ask to see the permit. We carry out no work, we sell no valves, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call. The maximum water temperature is set by your local code, not by this website.

What points to the body rather than the trim

Water appearing inside the wall, in a ceiling below, or a handle that turns without changing anything, all point past the trim. None of them are fixed by a new escutcheon.

Why the temperature swings

A valve that is not pressure-balanced sees the cold side drop when something else draws cold water, and the mix at the head follows it. That is the fault anti-scald valves were introduced to remove.
