Annual maintenance on sump pumps helps to ensure proper operation. Even though the SmartSump has an airtight lid to keep debris out, the liners that house these pumps can accumulate dirt and silt as the ground water moves through them and out of the home. Quality 1st Service Technician Chris takes care during maintenance to not only clean and test the system, but to also sanitize the liner and pump stands to allow the sump pump to continue keeping the crawlspace free of ground water!
