Is your sump pump gurgling? If you are hearing the sound for the first time, it can scare you for once. But there is nothing to worry about, it’s quite common!
The gurgling sound is an indication that your sump pump needs to get checked professionally.
Here, we have explained what you should do when your sump pump starts gurgling and the reasons behind the scary noises. Explore this detailed article to know how to fix your gurgling sump pump.
Why is your Sump Pump Gurgling?
First of all, you need to understand the function of your sump pump. The responsibility of a sump pump is to remove or pump water away from the basement and prevent it from flooding during high water levels.
It also helps keep basements dry by absorbing moisture and controlling the humidity level. Well, that means it also blocks the mold & mildew growth in the basement which is a common problem faced by homeowners.
Check if you are living in any of the areas facing:
- high rainfall
- heavy snowfall, and
- High water content in the soil
- high groundwater
If your answer is yes, then probably installing a sump pump is the most effective solution to keep water at bay.
What are the common causes of a gurgling sump pump?
A sump Pump is an electrical device and does create some noise when it’s running or discharging water into drain lines. Generally, it’s the air that causes the sound when it is released from the system after every pump cycle. The noise level also depends on the:
- Quality & design of sump pump.
- Location of sump pump where it is installed.
- Sump pump materials.
- The current condition of the sump pump.
But somehow, if the noise is quite uncommon then there can be some other reasons such as:
- There is a possibility that air has escaped into your sump pump due to overflowing and high water tables.
- Another potential reason can be drainage or blockage in the sewer system.
- Low size of sump pump basin.
- Poor maintenance and extended use are causing a problem in the mechanical parts of a sump pump.
How to Fix a Gurgling Sump Pump?
Sometimes, the problem is not that big enough. Rather than immediately calling a professional and wasting lots of money, start looking for the common causes that you can fix on your own.
Step 1: To begin with, check the intensity of the gurgling noises. Is it high, medium, or low almost similar to tap leakage? It matters the most in finding the root cause of the gurgling sump pump.
Step 2: Check if the sump pump basin has built up dirt, grim, and household debris. There is a possibility of debris being stuck into the pit and causing it to whirl around the pump pit.
Step 3: Now, check the level of water in your snake drain.
Step 4: Finally, check the water drain pipes. When the check valve activates the sump pump, make sure the water pipes are all tight, and not broken or leaking. The leakage in the water pipes airs to escape into the water lines. Thus causing the weird gurgling sound.
How to reduce the gurgling sump pump noise?
- Try wrapping insulation around the water pipes. It may minimize the noise if the vibration or clanging is due to water pipes coming in contact with the pump basin
- The other way is to cover the underside of the sump pump lid with rubber grommets. It’s an effective solution to reduce the motor rattling sound due to the pipe striking the sump pump motor.
- Check if your main discharge line has been fixed with various joints and angles. You can replace it to avoid air entering into your pipe and moving henceforth. Thus, it will prevent your sump pump from making gurgling noises.
- You can also be replacing your swing check valve with that of a spring-loaded check valve. It’ll help water run smoothly through the drain lines.
- Make sure to switch off the pump switch immediately if there is no water in the sump pump basin. If the basin is empty, the sump pump motor will create a sound that’s almost similar to sucking from a straw.
- Another way around this is to seal the exposed sump pump basin with fitted foam insulation, a rubber lid, or simply a piece of plywood.
Nowadays, most of the new sump pump models come with a fully insulated system and a PVC cover which automatically reduces the noise level.
Is your sump pump gurgling even if it is switched off?
Surprised? Yes, it happens too! Many a time sump pumps make gurgling noises even when they are not working, or when the pressure settles in the water drain lines. The pressure causes the air to move back and forth which then creates gurgling noises.
To stop the noise simply turn on your sump pump for a while.
Experts tip: Make sure that your sump pump has been installed inside the pit with a relief hole. It should be 12 inches up the drain lines.
Generally, gurgling noises are generated by old sump pumps. We have already discussed all the fixes that can save you time and money. If somehow, the sump pump is still making undisturbing noises, we suggest upgrading to the newer sump pump model or replace with new mechanical parts.
