A sump pump pit is a crucial part of your sump pump. It eliminate excess water that may gather in the crawlspace or basement. This water can cause many problems for the interior of your home, including mold growth, which can be very hazardous to your health. A sump pump pit installed with your sump pump will help prevent mold from growing.

Step 1 - Find the Problem Spot

Your sump pump pit needs to be located where the water accumulates. That will help the sump pump pit do its job properly. Even after you have picked the spot, you will still need to be sure that you have no drain lines or utility lines nearby.

If water accumulates around this area, then you should get as close to the area as possible while still steering clear of the lines. If you are unsure whether these lines are present, proceed slowly and carefully.

Another thing to keep in mind when it comes to the location is that the sump pump pit is not near any outside openings because the temperature in that area is much colder, putting the system at risk of freezing.

Step 2 - Digging

Dig the pit 2-feet wide and 2.5-feet deep. Ensure that there are no large rocks, roots, or other obstructions in the way. Taper the walls of your pit if needed. In order to determine the size of the hole you will drill, base it on the size of the liner that you are installing.

Step 3 - Liner Insertion

When inserting the liner, ensure that the liner fits smoothly and that it is level. All of the voids which surround the pit will need to be filled with dirt. Do so as needed until it is all completely filled. Doing so secures the liner in its place. It is very important that the liner is kept level throughout this entire process.

If laid correctly, the liner will allow water to pass, but it will block all debris and dirt. That is what keeps your sump pump working well over time, as dirt and other debris can do quite a bit of damage to your sump pump.

Step 4 - Additional Tips

If you already have the pump installed, make sure that the liner fits it properly. Leave 1-inch of clearance on every side of the sump pump.
