Pride Plumbing came out, and after inspection, provided a cost estimate to 1) either rebuild two leaking Kohler single handle bathtub/shower valves by replacing their cartridges or replace them with new Delta R10000-UNBX rough-in valves (this would include cutting accesses in their shower walls; adding Delta T13220 chrome trim kits (replacing the shower heads, valve covers and handles, overflow covers, and downspout push button diverters); converting the valves' 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 installing plastic plumbing access panels over the holes we cut in the wall); and 2) replace a non-working garbage disposal with either a new customer supplied model or a new Pride Plumbing supplied Insinkerator Badger 5 model along with replacing the kitchen sink's PVC waste piping and P-trap.
