Can a Generator Run a Sump Pump?

You need a sump pump to prevent damage from floods in your basement. As a safety measure, sump pumps are installed in the basement that pumps water out of your house when you feel the risk of flooding.

The pumps are powered electrically; therefore you must equip them before they can operate. There are cases where the storm can cause damage to the power lines and thus cause your house to suffer a power failure.

The generator to be used should have a high starting power. Sump pumps tend to use a lot of energy when starting.

The power increase can be up to 2000 watts before they stabilize and start at a continuous power of 500 watts.

To be on the safe side, you have to choose a generator with more than 2000 watts peak power. The generator size also depends on the size of your sump pump generator.

How to Install a Sump Pump Generator

The connection or installation of a generator to a sump pump can be a fail-safe device that can help prevent major water damage even if the power supply to the house or building fails during a storm.

Ensure your generator is clean, dry, secure, and to be fueled and use. Also, ensure that it’s oiled, keep charge the starter battery, and have a fresh fuel supply or a proper container and siphoning device if it uses the same fuel as your car.

Place your generator at least 15 feet away from windows when the time comes to use it.

To protect the running generator from heavy rain and loose connections, make little roofs for them.

Measure the distance between the sump pump and the generator outside. Use this measurement to determine the length of an extension cable you’ll need when installing the generator to the sump pump. Fill the generator with fuel until the tank is full.

Start the generator, and while it is running, briefly connect the extension cable to the sump pump plug to ensure that the sump pump is working properly.
