How To Install A Sump Pump


After heavy rains or flooding, where does all that water go? The obvious answer is, well, the ground. Over time, though, the ground becomes saturated and that water has nowhere else to go. That’s where a sump pump comes in. In today’s post, we’re going to fill you in on everything you need to know and how to install a sump pump for your home. When you live in a wet area, and Western North Carolina is very wet, you will want to have a sump pump where water likes to accumulate.


What Is A Sump Pump?

A sump pump is what it sounds like: a pump. The difference between a sump pump and a normal pump is that a sump pump sits underwater. Where do you put these pumps? In order for a sump pump to work as it should, it’s installed at the lowest point of your home. Often, the lowest point is in the basement or crawlspace. These small but mighty pumps prevent flooding in your home and save you thousands of dollars. 


How Does A Sump Pump Work? 

Sump pumps work as moisture guards. The pump is always on standby. When the ground around it becomes saturated, the built-up water drains to the pump pit. This pit slowly fills with water, and the float gauge inside the pump activates to kick on the motor. Once the pump removes the water, it drains into a storm drain, dry well, or retention pond. Essentially, the sump pump removes water before it reaches the level of your basement or crawlspace floor. A sump pump is a standby flood guard that acts as a form of flood insurance. 

Let’s dive into how to install a sump pump. 


Dig The Sump Pit

First, you need to prepare the sump pump location. With all pumps, you need a sump pit. The traditional measurements for a sump pit are about 30 inches deep and 24 inches across. You definitely want to make sure the pit is big enough to accommodate the pump. Make sure to dig the pit at the lowest point. 

Once the pit is dug, drill drainage holes in the side. Then, line the sides and bottom of the basin with filter fabric. The fabric will prevent the pump and pit from filling with dirt. 


Test The Float Valve 

Make sure the float valve moves up and down freely. If it doesn’t, the pump won’t cut on like it’s supposed to. 


Install Discharge Lines

Install either PVC or a flexible discharge hose to let the water drain outside the home. You’ll want to make sure there’s the proper slope. 


Test The Sump Pump

To test the pump, simply fill the basin to the top with water. If all is well, the pump should kick on and drain the water out. 


Other Considerations

So, now you know how to install a sump pump. Depending on your home’s soil, groundwater, and location, you may need more sump pumps. The best thing to do is reach out to a professional plumbing service that can help.
