Sump pumps can prevent basement flooding and save valuable items stored in the basement. They can also prevent mold and mildew that damages a home and affects health.
A float switch triggers the pump when water rises. The pump sucks the water up into the basin and directs it to a drain or away from your home.
Cost
Sump pumps are a cost-effective way to keep water out of the basement and avoid foundation cracks. They can also help you avoid removing carpeting, padding, and other expensive home contents. In the long run, they can save you thousands of dollars.
On average, a primary electric sump pump costs between $80 and $1,000. This includes the motor sitting on top of a pedestal or in a submersible unit, along with a hose system that draws water up and out to prevent flooding and mold damage.
A battery backup pump is an optional upgrade for any electric sump system, ranging in price from $150 to $2,000 depending on the quality of the backup. It runs on a rechargeable battery and turns on automatically during a power outage to remove excess water. This is ideal for homes in areas where frequent power outages occur.
Permits
The permit process for sump pumps can vary, but it’s important to know the requirements for your city. A licensed plumber can help you determine whether a permit is needed and help you navigate the permit process. This is especially important for a job like this, as improper installation can lead to costly water damage.
The discharge location of the pump or pipe drain must not create a public nuisance by causing a build-up of iceing, standing water or algae growth on the street, sidewalk or public right-of-way. It also must be located a minimum of 10 feet from the property line.
Sump systems that include battery back-up can help prevent flooding during large storms. These systems have a secondary pump linked to a controller that activates the backup pump when utility power is interrupted. The controller also draws power from the batteries to keep the backup pump running until primary utility power is restored.
Installation
If you don’t want to deal with the hassle of installing French drains or are not sure how much the cost will be, then a sump pump is a good solution for your basement. It is relatively inexpensive and is easy to install. It is also much less invasive than tearing up your basement walls for a more extensive system such as French drains.
A sump pump for your home works by using a centrifugal pump to move water. The motor turns a screw-like device called an impeller, which moves water to the sides of the pipe until it fills up a low pressure area at the center. Then the impeller turns again and pushes the water out through the float outlet. You can route the discharge pipe to the outside or into a receptacle in the basement. Make sure to add a vent hole that is out of the water (to avoid an air lock) and a GFCI outlet.
Maintenance
Sump pumps are an excellent way to prevent flooding and moisture in the basement, but like any plumbing appliance they can fail. A sump pump that is not working properly can cause water damage to the home and even ruin valuable items. It can also result in a damp basement that is perfect for mold and mildew growth.
A good practice is to test your sump pump every three months. Make sure nothing is lodged in the pit, valve, and discharge line that could obstruct the pump from functioning correctly. It is also a good idea to check the basin for cracks and other signs of wear and tear.
An older sump pump may need to be replaced as it approaches or passes its lifespan. Sump pumps generally last about 10 years. A sump pump that is switching on and off frequently during the day or rainy season can indicate it needs a replacement. This is because the switch can get stuck or the mechanical pressure switch may be failing.
