We size every sump pump to your basin, discharge distance, and Mount Pleasant, SC water table, not a generic off-the-shelf number.
An oversized or undersized sump pump both cause problems down the line — short-cycling, premature motor failure, or simply not keeping up during a real storm. We calculate GPH capacity against your basin's actual inflow rather than reaching for a default size.
Every sump pump installation is completed by a licensed, insured technician, with electrical work handled to code.
We carry common pump models on the truck so a failed unit can often be replaced the same day you call.
Battery backup add-ons are priced separately and clearly, so you can decide what fits your budget.
Oversized or undersized pumps both cause problems — sizing it correctly the first time avoids premature failure.
Every Mount Pleasant, SC Sump Pump Installation job starts with an inspection, not a generic package — here's what that typically includes.
A correctly sized primary pump is the backbone of any basement drainage system, and we match horsepower to your basin's actual inflow rate.
We size backup battery capacity to your typical outage duration, not just a default runtime estimate.
For homes with municipal water pressure, a water-powered backup pump runs without any battery at all, using house water pressure to move basement water out.
A missing or failed check valve lets pumped water flow back into the basin, making your pump work twice as hard for the same result.
An undersized basin cycles the pump too frequently, shortening its lifespan — we resize basins when the existing one isn't keeping up.
Tell us your pump's age, symptoms, and whether it failed or you're installing new — that shapes what we bring on the visit.
We also check the discharge line route and check valve condition as part of the same visit.
You'll see the recommended pump horsepower, basin size, and any backup options broken out with pricing.
You'll get a quick walkthrough of the alarm and backup system operation so you know what to expect.
