What to Expect with Sump Pump Installation
Installing a sump pump in a home that doesn't currently have one is a significant investment in your property's protection. The process involves excavating a sump pit (if one doesn't exist), installing a basin liner, setting the pump, running discharge pipe to the exterior, and installing a check valve to prevent backflow.
A standard submersible pump installation typically takes 4–8 hours for an experienced contractor. The discharge line must terminate at least 6 feet from the foundation and slope away from the house — easy to get wrong and critical to get right. Poor discharge placement is one of the most common causes of new installation failures.
We strongly recommend pairing a new primary pump with a battery backup system from day one. The battery backup activates automatically when the power goes out — which frequently happens during the same storms that cause flooding. Most municipalities require a permit for sump pump installation; your contractor should pull this as part of the project.
