Pride Plumbing came out and repiped and replaced the drain lines under the house in the crawlspace, going to a) the fixtures in the kitchen (sink and dishwasher) and two bathrooms (sinks, toilets, and bathtubs/showers - replacing the toilet bowl flanges and wax ring gaskets, the bathtub/shower drains, and the P-traps underneath all the sinks, and the bathtub/shower's waste and overflow); and b) the washing machine - installing new PVC piping, fittings and supports under the house and up through the flooring for each fixture.
