Pride Plumbing came out and performed the following work: 1) raised a three-bay stainless-steel kitchen sink to a height that allowed its drain to gravity-feed into a Liberty 404 residential drain pump; 2) installed the drain pump beside a third stainless-sink and ran its PVC vent pipe up the wall to a seven-foot height; 3) ran a separate PVC drain line (with ball and check valves) through the wall to a bathroom and tied it into the main drain stack; 4) at a utility sink, added a Santee and air admittance valve and ran its drain into the main drain stack; 5) installed a new P-trap, Santee, and air admittance valve on a bathroom sink and connected them to a drain located in the floor; and 6) tested all installations/repairs for leaks and proper working order.
