Pride Plumbing came out and performed the following work: 1) cut and removed the PVC drain lines going to a handwashing sink; repiped the new PVC drain lines to meet recently revised plumbing and venting codes - using the sink's existing air admittance valve - and tested the sink and drains for leaks and proper drainage; and 2) cut and removed the P-trap at the wall using a hub-saver tool and reduced the drain piping down to 2-inches for a grease trap discharge line; installed a new 2-inch PVC discharge line coming from the grease trap going to the sewer line - using an existing 3-compartment sink's air admittance valve; and tested the new discharge line for leaks and proper drainage.
