Pride Plumbing came out and installed a plastic plumbing access panel on a shower wall. We also provided a cost estimate to replace the two-handle bathtub/shower faucet valve. This would require us to replace the shower valve with a new Gerber model (along with short sections of its hot- and cold-water supply lines with new PEX piping and fittings), shower head, and downspout diverter, and add new handles along with stems, washers, seats, and escutcheons.
