Basement Sump Pit Pump Installation With Battery Backup System

Looking for an experienced plumber or contractor to install a complete sump pump system in my basement sump pit. The pit is already excavated and lined, roughly 18 inches in diameter and 24 inches deep, but currently has no pump installed and water has been pooling after heavy rain. Scope of work: assess the pit depth and inflow rate to size an appropriately rated primary submersible pump; install the pump on a solid base with a check valve directly above the discharge outlet to prevent backflow; run rigid PVC discharge piping through the rim joist and route it across the yard to a splash block or dry well at least ten feet from the foundation, with correct grading so water drains away rather than back toward the house; wire in a dedicated GFCI-protected outlet if the existing circuit is not adequate; install a battery backup pump system with a deep-cycle battery and charger so the pit keeps draining during power outages, which is when basement flooding risk is highest; calibrate the float switch so the pump activates at the correct water level without short-cycling; set up a high-water alarm that will alert us audibly if the primary pump fails or cannot keep up; and run a full test cycle by filling the pit and confirming both the primary and backup pumps engage, discharge properly, and shut off cleanly. Please also inspect the pit liner and lid for cracks or gaps that let in soil and recommend a sealed lid if needed. We would like photos of the finished installation and a brief written summary of the equipment used, including pump horsepower and battery capacity, for our records. Available to start within the next couple of weeks; please include your estimated timeline and whether you carry your own materials or need a supply list from us.
