What they do
Flowline Plumbers Kitchener does basement flooding work in houses, mainly around Kitchener, Waterloo, Cambridge and Guelph. Its sump pump work covers checking the pit, switch and discharge line, repairing a unit or fitting a new one, and battery backup sump pumps for power cuts. It also installs backwater valves on the main drain to keep sewage from the city line flowing into lower fixtures, and handles sewer backup prevention and drain cleaning. Work is quoted at a flat rate before it starts, and old water heaters are hauled away when replaced. Founded in 2003 and locally owned, the company carries WSIB coverage and gives a one-year warranty on its workmanship, with certain parts also covered by the manufacturer.
