Pride Plumbing came out and provided a cost estimate to repipe and replace 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 will also remove a grey drain line and tie the water heater's T&P valve into the drain line for the washing machine.
