A sump pump is a device that helps to remove water that has accumulated in a water-collecting sump basin. They are commonly used in basements that are below grade or have poor drainage around the foundation. Sump pumps come in two different designs: submersible and pedestal. Submersible pumps are designed to be placed underwater in the sump pit, while pedestal pumps are designed to sit outside of the pit.
There are many factors to consider when choosing a sump pump, such as the size of your basement, the amount of rainfall in your area, and whether you live in an area with high groundwater tables. It's important to choose a pump that is powerful enough to handle the conditions in your home, but not so powerful that it will cause problems with your plumbing system.
Sump pumps require regular maintenance to keep them running properly. The most important part of maintenance is making sure that the pump's discharge pipe is clear of any debris or obstructions. You should also check the float switch regularly to make sure it is functioning properly.
