5 Reasons Your Sump Pump Is Making Noise & Ways to Fix

5 Reasons Your Sump Pump Is Making Noise & Ways to Fix

Sump pumps protect basements from flooding and water damage. When it rains, snows, or ice melts, water absorbs into the ground. Unfortunately, some of this water seeps under your home’s foundation. A sump basin, sump pump, and discharge pipes work together to remove this excess water.

The water collects in the sump basin, and when the sump basin fills up, the sump pump sucks up the water and pushes it through the discharge pipe away from your home. If you have a basement in your home, you should have a sump pump. Is your sump pump making noise? Check out these five common reasons why this might be happening.

Why Is My Sump Pump Producing Strange Sounds?

1. Humming Noises

If your sump pump is making a humming noise but is not pumping water correctly, you should do a maintenance check to see what might be causing the issue.

How do you stop your sump pump from humming? The source of the humming sounds may be a clogged vent, stuck check valve, frozen discharge pipes, or a broken impeller. If you notice a humming noise, do a quick maintenance check of your sump pump.

2. Grinding Sounds

If your sump pump makes a grinding noise, check it as soon as possible. The culprit might be a jammed or defective impeller. The impeller carries water into the sump pump. If this part is damaged, it needs immediate attention to prevent leaks or flooding. If the impeller is jammed, clear the jam. If the impeller is defective, replace it with a new one.

3. Banging Noises

Loose discharge pipes might be the reason why your sump pump is making a banging noise. The discharge pipe is the component that removes water from the sump basin. If this piece doesn’t function properly, it could lead to flooding.

You may be able to resolve the issue by securing the loose pipes with wire. In addition, you will want to consider adding an extra bracket where the noise originated. If you need help fixing a sump pump that is making a banging noise, call a professional to perform a maintenance check.

4. Gurgling Sounds

Are you wondering why your sump pump is making a slurping or gurgling sound? A gurgling noise coming from your sump pump indicates that water is flowing back through the discharge pipe. Here are some ways to fix this problem:

  • Replace the check valve with a quieter version
  • Modify the pump basin’s automatic turnoff level

Call a plumbing expert with any questions or concerns.

5. Clanging Noises

A clanging noise coming from your sump pump means that one or more parts are vibrating vigorously. Here are some quick fixes for this problem:

  • Insulate the piping
  • Put rubber grommets below the lid
  • Fix the position of the discharge pipes

The first two solutions are easy to implement at home, but the third solution might warrant the help of a professional.

Types of Primary Sump Pumps

Finding the right primary sump pump for your home’s needs is crucial to prevent flooding. Here are the two kinds of primary sump pumps:

Pedestal Sump Pumps

Pedestal sump pumps are tall and skinny. This type of pump sits on dry ground and is designed to pump water from narrow or shallow sump basins.

Pedestal sump pumps last longer than submersible sump pumps because they don’t incur water damage. Advantages of installing a pedestal pump include compact size, minimal deterioration, and longer life cycles. In addition, a large number of homeowners choose to invest in pedestal sump pumps because they are cheaper than submersible pumps.

Submersible Sump Pumps

Submersible sump pumps are short and fat. They submerge in the water of your sump basin and operate underwater. If your sump basin is deep and wide, a submersible sump pump is the better option for your home.

Benefits of Submersible Pumps

  • Low noise level
  • Water cools the motor to prevent overheating and malfunctioning
  • Stronger than pedestal pumps
  • Removes solids and debris
  • Stronger horsepower
  • Faster pump rate
