Pride Plumbing came out and provided a cost estimate to replace a leaking ball-style single-handle Delta walk-in shower faucet valve with a new single-handle Delta model with chrome trim (shower head, faucet valve handle and cover, and drain covers). This would include cutting an access in the shower wall and replacing the valve along with short sections of its hot- and cold-water supply lines with new PEX piping and fittings.
