Drain Tiles, Sump Pumps, and Sump Pits

Foundation Drainage System Overview

Your home is equipped with a perimeter drainage system installed around and/or beneath the foundation and basement. The purpose of this system is to collect and redirect groundwater away from your foundation to help prevent water intrusion and basement flooding.

Depending on your lot’s elevation, this system will drain either:

• To daylight (gravity-fed discharge), or

• To a sump pit and pump (commonly required on flatter lots)

  
  

If this drainage system becomes blocked, obstructed, or fails for any reason, water can back up and potentially flood your basement.

Daylight Drains

If your foundation drainage system discharges to daylight, it is important to regularly confirm that the outlet remains free and clear. Ensure the discharge pipe is not obstructed by:

• Dirt or topsoil

• Vegetation or landscaping

• Debris or sediment

• Ice or snow buildup

• Animals or nesting

• Exterior surface flooding

Any blockage can prevent proper drainage and lead to basement flooding.

Sump Pits and Pumps

If your drainage system discharges into a sump pit, proper operation and routine checks are critical. Please ensure the following:

• The sump pump is plugged in and has power

• The float moves freely and is not obstructed or stuck against the sides of the pit

• The sump pit is free of debris

• The pump operates properly — test it regularly, especially before and during heavy rainfall

• Consider having a backup pump and a water or pump-failure alarm for added protection

Additionally, make sure the sump pump discharge pipe outside the home remains clear of dirt, soil, vegetation, debris, ice, snow, animals, or flooding. Any obstruction can cause pump failure and basement flooding.

Drain Use Reminder

Do not dispose of debris or allow excessive sediment to enter garage or basement floor drains. Over time, this can lead to blockages within the drainage system and reduce its effectiveness.

During construction, it is common for basements to experience water intrusion or temporary flooding—especially in homes that require a sump pit and pump. This condition is normal and unavoidable during certain phases of construction. Until the home’s permanent drainage systems, sump pump, roofing, siding, and other protective elements are fully installed and operational, there is nothing in place to prevent water from entering or accumulating in the basement or to actively remove it.
