The Pump's Not Running!

My Sump Pump System Won't Turn On!

Sump pumps can fail to turn on for a variety or reasons, including clogs in the system, a power failure, and an issue with your pump's float switch.

Our full-time waterproofing service department will occasionally get calls from homeowners who has a sump pump system installed that will not turn on.

The sump pump is the heart of your basement waterproofing system. Without it, there is no way for the water collected by your perimeter drain to exit the home.

At Basement Systems UK, our dealers take special care to build redundancy into your sump pump system, so that you always have extra protection if one sump pump fails.

We recommend installing a primary sump pump, a powerful secondary sump pump, and a battery backup pump system in your home. This will protect you from all the primary reasons for sump pump failure -- including mechanical failure of the sump pump, overwhelming water volumes, and power outages.

Why Sump Pump Systems Fail To Turn On

When a sump pump system fails to turn on, a flooded basement is not far away. And while knowing the cause of your issue is an important step to solving the problem, the best defense against a failing system is to install a high-quality sump pump to begin with.

At Basement Systems, we recommend installing a submersible, cast-iron sump pump with a secondary sump pump and a battery backup system. Submersible pumps are self-cooling and the cast-iron design will last the longest in your home. A well-designed system with backups in place will minimize the chance of failure and help to ensure a dry basement.

The four major causes of this type of sump pump problem include the following:

A clogged sump pump system filled with mud.

The System Is Clogged

A properly working perimeter drain system is designed to collect water from the perimeter of the basement and direct it to your sump pump. If that drain has become clogged with mud, debris, or iron ochre, then your sump pump system will have no water to pump away from your home.

These drain clogs are most common when there is a large, open gap along the floor. This gap, which is designed to collect water from the walls, can also collect debris from the basement floor.

Alternatively, the sump pump itself can clog when large pieces of debris enter the pump. Sump pumps with filter screens will also clog over time as the filter becomes clogged with debris.

Your Sump Pump Has Burned Out

Overheating is the primary cause of mechanical failure of the sump pump itself. The motor of a sump pump creates a lot of heat. Any system that can easily disperse that heat away from it will last much longer than the alternative.

The best sump pump systems are those that can be submerged directly in water. This allows them to be cooled by the groundwater as they pump that water out. Submerged cast iron sump pumps are ideal to transfer heat from the pump, provided that the center cylinder of the sump pump's housing is cast-iron and not just the base.

It's also important to have a properly sized sump pit. A sump pit that's too large and too deep will force the sump pump to continuously and unnecessarily switch on.

A sump pit that's too small will force the sump pump to turn on and off more often as the water is pumped out, which will contribute to its burning out.

The Pump's Float Switch Has Failed

A sump pump turns on and off based on the position of its "float switch". As water rises in the sump pit, the switch will rise and fall. When it rises to a certainly level, the sump pump switches on and pumps out the water. As the float switch lowers with the water level, the system shuts off again.

Sump pump systems create vibrations as they run, and over time, they can "wander" around the sump pit. If this wandering results in the float switch being pressed against the side of the sump pit while in the "off" position, then your system will be unable to turn on.

Alternatively, some float switches are hollow, and they fill with water. A water-filled float switch may not rise as it should, resulting in a system that doesn't turn on.

There's A Power Issue With The Pump

Sump pumps can lose power for a great number of reasons. At Basement Systems UK, we find that all of the following are common:

  • The sump pump was unplugged because the outlet was needed for something else and was never plugged back in.
  • There was a blown fuse on the circuit where the sump pump is plugged.
  • A power outage during a rainstorm has led to the sump pump not running.
  • A low-energy battery backup has run out of power.

We recommend installing the primary and secondary pumps on two different circuits, and installing a long-lasting battery backup system -- like our UltraSump® Battery Backup Sump Pump.
