82% of homes were built before 1990.
Free to homeowners in San Francisco — the contractor pays us for the introduction, you never do.
The short answer
In San Francisco, 82% 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.

82% of homes in San Francisco were built before 1990, which is broadly before pressure-balancing anti-scald valves became the default fitting in new work.
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.San Francisco in numbers

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.
Cartridge or valve body
A shower that drips is usually the cartridge, which is a part. A shower that will not hold a temperature when a tap runs elsewhere is usually the valve, which is behind the wall.
