A licensed plumber fixes sump pumps. Sump pump work involves electrical (the pump is plugged into a GFCI), water (a check valve and discharge line that must hold water under pressure), and the pump pit itself — all of which a plumber is trained for. Mainstream’s plumbers repair, replace, and add battery-backup pumps in one visit.
