Sump Pumps & Interior Drainage

Every sump pump fails eventually. The question is whether it fails while you are watching, or while you are away for the weekend.

What this actually is

Interior drainage collects the water that has already reached the inside of the footing and routes it to a sealed pit, where a pump lifts it out and discharges it far enough away that it does not simply return.

Sizing is the part most installations get wrong. A pump has to clear the peak inflow of the worst storm, not the average one, and it has to do that against the real vertical lift and pipe run of your building, not a number off the box.

We size the pump to measured inflow, seal the pit to keep soil gas and humidity out of the basement, fit a check valve and an alarm, and specify a battery or water-powered backup so the system survives the outage that usually comes with the flood.

Signs you have this problem

  • No sump at all in a basement that takes water
  • A pump that runs constantly, or cycles every few minutes
  • A pit that fills faster than the pump can clear it
  • Discharge that dumps right next to the foundation
  • No backup for when the power goes out in the storm that needed it
  • A pump over seven years old that has never been serviced

How the work runs

Every job in this category follows the same order.

  • 01

    Measure the inflow

    What the basement actually takes on, and how fast, so the pump is sized to the building rather than the catalogue.

  • 02

    Interior drain line

    Channel cut at the footing, piped to the pit, with the slab restored over it.

  • 03

    Pit and pump

    Sealed basin, primary pump, check valve, high-water alarm and a discharge run that goes somewhere useful.

  • 04

    Backup power

    Battery or water-powered secondary pump, so an outage during a storm is not a flood.

  • 05

    Test under load

    We fill it and run it, and show you the alarm working and the backup taking over.

What is included

  • Inflow measurement and pump sizing
  • Interior perimeter drain where required
  • Sealed sump basin and lid
  • Primary pump, check valve, high-water alarm
  • Battery or water-powered backup
  • Discharge line routed clear of the foundation
  • Workmanship guarantee

Questions people ask

Sump Pumps, answered plainly.

If losing the basement matters to you, yes. The storms that overwhelm a sump are the same storms that take the power out, and a primary pump on a dead circuit is an ornament.

Usually. It means cutting and restoring slab and dealing with the finishes above it, which we scope and price explicitly rather than discovering halfway through.

A correctly sized pump in a sealed pit is quieter than a dishwasher, and runs for well under a minute at a time. A pump that is loud and constant is a pump that is wrong for the building.
