A first visit usually means finding where water enters, choosing a pit location in the wettest part of the basement, and walking the yard to see where the discharge can go. Bring out your septic as-built plan from the Board of Health so the plumber can see where the tank and field sit, and point out the wellhead.
The work typically involves cutting the floor, setting a pit liner, installing the pump with a check valve, and running the discharge through the wall to a spot that drains away from the house. A new dedicated outlet is electrical work: Carver requires electrical permits for many jobs, and since April 1, 2026, every electrical permit application has needed an inspection request form, a copy of the electrical license and insurance, and the fee.
Many mobile homes and some ranches have a crawlspace instead of a basement. There, the fix may be a crawlspace pump or drainage changes outside, so ask what fits your foundation.
