Pride Plumbing came out and replaced a leaking three-handle bathtub/shower valve with a new Gerber G004803083 three-handle model (this included cutting an access in the shower wall, replacing the valve along with short sections of its hot- and cold-water supply lines with new PEX piping and fittings, adding new stems, washers, seats, handles, and escutcheons, installing the shower head, downspout diverter, and a plastic plumbing access panel over the access hole we cut in the wall).
