Your Complete Guide to the Sump Pump Basin Holes

If you live in a flood-prone area, you already know that a sump pump basin is an essential component of any sump pump system, yet many people don’t know what they are or how to maintain them properly. This guide will go over everything you should know about sump pump basin holes, including what they are, why they’re essential, and how to keep them clean and functional.

What Are Sump Pump Basin Holes?

The sump pump basin is the lowest part of the sump pump system, and it’s where all the water collects before being pumped out. The basin is usually made of plastic or metal and has several holes drilled into it that allow water to enter.

These holes are called inlet holes, and their purpose is to allow water to flow into the basin from the surrounding area. In most cases, the inlet holes are located near the bottom of the basin so that water can easily enter as it collects.

Why Are Sump Pump Basin Holes Important?

The sump pump basin holes play a vital role in the proper operation of the sump pump system. Without these holes, water would have nowhere to go and would simply build up around the sump pump, eventually flooding.

In addition to allowing water to enter the basin, the sump pump basin holes also allow air to flow into the system. This is important because it helps keep the pump working properly by preventing it from overheating.

Location Guide and Basin Hole Size

Every sump pump basin is different, so there’s no set standard for how many or what size the holes should be. Typically, you’ll want to have a few holes about 1/4 of an inch wide (our recommendation) to get water and air to enter the system easily.

The best location in the sump pump basin for drilling holes is about a few inches above the bottom. However, do not drill too near to the sides or into the base of the pit. Drilling too near to, or straight into, the bottom of the sides may destroy the pump’s suction, driving it to run frequently and prematurely wear out the motor.

It’s simple to drill the holes. Remove the basin and dry it first. Then, attach a 1/4-inch drill bit to a drill and press down firmly into one of the pits’ sides until you’ve drilled a hole!

The Number of Holes Needed

The number of holes you’ll need to drill will depend on the size and shape of your sump pump basin. However, a good rule of thumb is to have one hole for every square foot of surface area.

We suggest drilling at least four holes. The exterior part of the basin should be surrounded by a circle of evenly spaced holes around it.

You can always start with fewer holes and add more if needed. It’s better to have too few than too many, as too many holes will decrease the pump’s efficiency and could cause it to overheat.

Maintaining Your Sump Pump Basin Holes

Once you’ve drilled the sump pump basin holes, it’s important to check them regularly to make sure they’re clean and functional. Over time, sediment and debris can build up in the holes and block them off, which will prevent water from entering the basin and cause the system to fail.

To clean the basin holes, simply remove any debris collected around them. A small wire brush can be used to remove any stubborn buildup. It’s also good to check the holes every few months to ensure they’re clean and functioning properly.

Fixing Sump Pump Basin Floating Issues

One common problem with sump pump basins is that they float up out of the pit when there’s too much water in them. This is usually caused by a hole being drilled too close to the edge of the basin, which allows water to enter and cause it to float.

If your sump pump basin is floating, you’ll need to move it back into place and drill new holes further away from the edge. Once you’ve done this, your basin should stay in place and function properly.

Frequently Asked Questions

Should the sump pump basin have holes?

The sump pump basin should have holes to allow water and air to enter. These holes play a vital role in the system’s proper operation and help keep the pump working properly.

How many sump pump basin holes do I need?

There is no single answer to this question, as every sump pump basin is different. However, it’s recommended that you have one hole for every square foot of surface area in the basin.

How can I keep my sump pump basin holes clean and clear?

You can keep your sump pump basin holes clean and clear by regularly removing any debris that builds up around them. A small wire brush can help clear out stubborn buildup. You should also check the holes periodically to ensure they’re functioning properly.

Why does the sump pump basin have holes?

The sump pump basin has holes to allow water and air to enter. These holes play a vital role in the proper operation of the system by helping to keep the pump working properly and preventing it from overheating.

Is the sump basin perforated?

When the water rises up along the foundation, it is channeled into your sump pit via perforated and flexible drain tiles (pipes).

Can you replace a sump pump basin?

Yes, you can replace a sump pump basin. However, you’ll need to remove the old one and install a new one in its place, which may require some basic plumbing skills or professional assistance.

Conclusion
