Why Your Sump Pump Needs A Weep Hole And How To Install One

A flooded basement is a home owner’s nightmare. Every household must have a drainage system; otherwise, where would the excessive water go? A weep hole is a perfect fix to a moisture-prone basement. It allows the trapped moisture and water to escape, thereby preventing the air lock. But how do we drill a weep hole into the sump pump? And a lot of people think the weep holes are perhaps unnecessary, is it though? To find an answer to your many questions, read along!

Sump Pump Weep Hole: An Ultimate Escape

A proper drainage system should be your priority. If it goes overlooked, you might end up ruining your household as well as your health. Installing a sump pump has, interestingly, more benefits than you think. A weep hole, however, gives your sump pump an edge in performance by preventing air lock. An air lock occurs when air bubbles get trapped along the discharge pipe. It can happen if your sump pump lacks a weep hole. Because the air has nowhere to escape, the water level will flood all over your basement, and that would be an absolute disaster. So, how will you install a weep hole in your sump pump?

Why Your Sump Pump Needs A Weep Hole

How to Install A Weep Hole in A Sump Pump?

To prevent air lock in your sump pump drainage system, follow the mentioned procedure step by step.

Assemble and drill!

  • Start with assembling your sump pump and its PVC pipes.
  • Firstly, start drilling with a 1/8″ inch drill bit.
  • This must be done at an angle of 45 degrees.
  • Ensure that the hole is directed downwards.

Note: The 45-degree angle should be strictly maintained so that the hole points downwards and not upwards since we would not prefer the idea of the drained water to spray in another direction or go up like a fountain!

Let the air escape

  • The drilled hole should be at least 6 inches above the sump pump’s check valve.
  • The water will spill out at first, but eventually, the locked air will escape. The sump pump weep hole is a preventive measure that helps to keep your basement dry.

Ensure a routine check-up

  • After you have successfully installed a weep hole in your sump pump, make sure you don’t let it get clogged.
  • A clogged weep hole and a sump pump without a weep hole is the same thing. Eventually, it will stop pumping water and be the reason for your sump pump’s death.
  • So, make sure that you clean the weep hole along with your sump pump.

Does Your Sump Pump Already Have A Weep Hole?

At times, you will notice a hole at the base of the pump. Refrain from confusing this hole with a weep hole because both have a completely different function. A hole on the side of the pump’s base exists to prevent the air locked from within the pump. However, the weep hole, which is above the check valve, prevents air lock between the pump and the valve.

Both the holes are preventive measures and must be checked routinely to avoid air locked sump pumps.

How large is a weep hole?

Ideally, the dimension of a weep hole is 3/16”. The measurement of the hole has to be precise for it will be ineffective if it is any smaller or larger. You can easily drill a hole by using a power drill.

Where should the weep hole be on a sump pump?

Normally, it is drilled below the waterline, however, the location of the weep hole can differ, depending on the model of the pump. You can check the owner’s manual to spot it right away.

Is a sump pump weep hole necessary?

Weep holes or relief holes serve the purpose of relieving the air that gets locked in the impeller chamber of the pump. If the air builds up inside the pump, it does allow the next cycle to start. That is why it is important for sump pumps to have weep holes. Also, it extends the life of the sump pump.

To Conclude

A heavy-duty sump pump requires a weep hole to ensure proper drainage. However, a weep hole in your basement will keep weeping away (pun intended) if there is no weeping tile system. I hope our guide has helped you to get some insight into weep holes and weeping tile systems. With this knowledge, you can routinely check and maintain the drainage system of your house. There you have it- you can’t have a sump pump without a weep hole. Now that you know it’s important- buckle up and give your pump the boost it needs.
