Pride Plumbing came out and provided a cost estimate to perform the following work: 1) drill a hole in a firewall, insert galvanized piping, and connect to a 3-inch vent pipe behind a water fountain in the ceiling; 2) apply flame resistant caulking around the hole made in the firewall; 3) install a kitchen sink and cabinet; 4) underneath the kitchen sink, install a 6-gallon Liberty pump system; 5) extend the PEX water supply lines from an Elkay water fountain through the ceiling and over to the new sink and a water heater; and 6) connect the Liberty pump system to the galvanized pipe in the firewall.
