Pride Plumbing came out and provided a cost estimate to perform the following work: 1) mark on the concrete floor the area to be trenched out; 2) saw, jackhammer, and dig out a trench across the room from one wall to the other; 3) place piping in the floor and make the drain connections on both sides; 4) mix concrete and fill in the trench and cover the new piping; and 5) replace all affected fixtures and reconnect their water and drain lines.
