Pride Plumbing came out and provided a cost estimate to perform the following work: 1) use a pipe level and make adjustments to the grades of the drainpipes underneath the building; 2) make adjustments to the hangers supporting the pipes and replace or repair any that are broken and that caused the back grade on main drain; 3) use a Hydro Jet water pressure device to remove buildup inside the drain pipes; and 4) insert a camera into the drain line to check for any additional issues and proper working order.
