Pride Plumbing came out and provided a cost estimate to repipe and replace the cast iron drain lines under the building in the basement, going to the floor sink drains and all the fixtures in the bathrooms (sinks, toilets, and showers - replacing the toilet bowl flanges and wax seal gaskets, the P-traps underneath all the sinks, and the bathtub/shower's waste and overflow); installing new PVC piping, fittings and supports for each fixture.
