Pride Plumbing came out, and after cutting an access in the wall, replaced a leaking bathtub/shower faucet valve with a new customer-supplied Moen rough-in valve; added a chrome trim kit (replacing the shower head, handheld wand, valve cover, and handle); converted the valve's copper above-floor hot and cold water supply lines to PEX piping and fittings - tying them into the home's existing copper main water lines; and installed a plastic plumbing access panel over the hole we cut in the wall.
