Installing A Sump Pump

This article is to show you how to install a sump pump into a basement floor.

How To Install A Sump Pump








Ideally you should be locating your sump pit at the lowest point of your basement floor (use a level to determine where that point is).

The site for this pump was determined by water that entered this basement during the 10″ rain storm we had last month.

The sump location should be near an exterior wall and located close to an electrical outlet (if possible). The pump will need to be plugged into a GFCI protected circuit. Although it’s code, I find that GFCI outlets often fail when overheated or when the pump cycles on and off.

I had my electrician install a dedicated 20 amp circuit for this location.

Determine where the pumps discharge pipe is going to run out of your basement. Most people drill through a rim or header joist to exit the house. This job is a bit unique and requires us to be a bit more creative, which I will share with you in the next two posts.

Mark Floor

The first step is to set sump basin upside down on basement floor and mark its outline on floor.

I decided to score the basement floor with my wet saw so I squared off my circle and added 2″ on each side for my clean gravel.

My wet saw cuts down to 2″ and I’m assuming the floor is 3+ inches thick. The saw kerf will make a nice clean hole and subsequent patch.
