A sump pump is one of the most overlooked yet essential pieces of equipment in a home. Tucked away in a basement or crawl space, it quietly stands guard against water intrusion, ready to activate when heavy rains, snowmelt, or rising groundwater threaten to flood your home. But like any other system, a sump pump requires regular maintenance to function properly. Without it, you could face costly water damage, mold growth, and even structural issues.
