The short answer
In Diamond Bar, 92% of homes predate 1990. A dripping shower is usually the cartridge; one that swings in temperature when another tap runs is usually the valve body, which sits behind the wall.

What this site is
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.Diamond Bar in numbers

Cartridge or valve body

Access is the cost
Replacing a valve body usually means opening the wall behind it, or working from the other side. Ask which, and who makes it good, before the work starts.
