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 one and one-half bathroom (sinks, toilets, and bathtubs/showers) - replacing the toilet bowls' flanges and wax seals, the P-traps underneath all the sinks, and the bathtub/showers' 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. We also removed a grey drain line and tied the water heater's T&P valve into the new drain line for the washing machine.
