While basements are uncommon in Northern California, sump pumps are not—they are invaluable to keeping excess water out of many homes.
High water tables and the risk of flooding during our rainy season make them a common plumbing product for many residential properties in Marin, Napa, and Sonoma counties, and all the surrounding areas.
External factors are not the only concern; homes are also susceptible to flooding caused by plumbing issues. A burst pipe or a faulty faucet can release a large amount of water into a house. If the automatic shut-off valve isn’t engaged promptly, substantial water damage can occur to a home and its contents.
Sump pumps offer a solution by automatically activating when water enters the sump pit, continuing to operate as long as there is water to be removed. By eliminating excess water, sump pumps control humidity and prevent the growth of mold, mildew, and wood rot, which can cause significant damage to homes.
