Pride Plumbing came out and performed the following work: 1) marked on a concrete floor an area to be trenched out; 2) sawed, jackhammered, and dug out a trench across the room from one wall to the other; 3) placed PVC drain and PEX water piping in the floor and made the drain connections on both sides, roughing them up inside a wall access; 4) filled in the trench with gravel and then mixed concrete and poured it in the trench, covering the new piping; 5) replaced all affected fixtures and reconnected their water and drain lines; and 6) installed PEX water supply lines for a new water heater, washer box, and laundry sink.
