Of every flooded basement we've responded to in Lagunitas-Forest Knolls, CA, a measurable share started with a sump pump that was undersized, neglected, or installed without proper discharge planning.
A sump pump is the last line of defense between groundwater and your finished basement. Metro Rooter Plumbing Service installs, replaces, repairs, and maintains sump pumps in Lagunitas-Forest Knolls with one principle: the pump must be sized correctly for the actual water volume the basin sees, the discharge must move water far enough from the foundation, and a backup must exist for the moments when primary power fails.

Why Most Failed Sump Pumps Failed Their Owners Before They Failed Mechanically
