Reasons & Solution of Sump Pump Sounds Like Washing Machine

1. Sump Pump Bubbling Sound

Reason of Sump Pump Bubbling Sound

A working sump pump usually makes bubbling sounds. Many users, as well as plumbers, find it normal. These bubbling sounds can be due to the movement of the flap of the check valve. This sound can be continuous as the flap tends to move up and down each time the water is pushed upwards. If you have a low-quality check valve or if the old one needs replacement, then the sound produced can be troublesome.

Solution of Sump Pump Bubbling Sound

The reason behind the bubbling sound is either a shabby or an outworn check valve. So, you will have to get a new one in order to have silent and working sump pumps. Well, the quiet check valves are one of the best options when it comes to having a non-clamorous pump. These sump pumps have springs that prevent the sound produced by the sudden closing and opening of the check valve. So, if you want to get rid of the bubbling sound produced by the constant slamming of the flap in the check valve, then replace it right away.

2. Gulping Sound of a Sump Pump

Reasons of a Sump Pump Gulping Sound

The gulping sound can be a little more disturbing than the bubbling sound. It can require some extra effort as this sound can occur because of an inappropriate level of water in the underground sink that is set as the triggering point for the turning off of the sump pump. If the level of water is set below the end point of the pipe that is placed in the underground sink, then the pump will still work till the water reaches the set level. This will produce a gulping sound before the pump stops automatically after reaching the level that you have set as the turning-off limit for the sump.

Sump Pump Gulping Sound Solution

As the sound is produced because of the low level of the water in the sink, you will have to set the turn-off water level higher than the previous one. Some of the sump pumps don’t need such adjustment as they have an automatic built-in system that senses the level of water within the underground pit. The pump stops forcing the water into the pipes when the water goes below the level of the sensor. While the pumps that need to do it manually require a little more hard work as you will have to open the lid of the sink in order to change the selected level.

3. Sump Pump Trembling sound

Reason of Sump Pump Trembling sound

A trembling sound can be experienced if you have an issue in setting up the sump pump. The pump has a powerful motor that pushes the water up the discharge pipes. If these pipes are not anchored properly or are placed close to other pipes, they might touch each other because of the high pressure of the water flowing through the pipes while the water is pumped out of the underground sink on your floor. I once faced such an issue because the discharging pipes were attached to the base of the ground floor, which might be the problem in your case too.

Sump Pump Trembling Sound Solution

In order to get rid of this type of noise, you can either change the position of the discharging pipes, which can be really hectic and time-consuming, or you can change the position where the pipes are anchored. If the noise is produced because of the close placement of pipes, then you can separate them by placing some soft material in between them. But, if the sound is produced because of the pipes being anchored into the base of the upper floor, then you will have to change the position. Anchoring the discharge pipes into the wall of the basement might be a good option.

4. Grinding Sound of Sump Pump

Reasons of Sump Pump Grinding Sound

This might be the sound that a sump pump user might never want to hear as fixing this problem can become a nightmare. Such sound is produced when there is a serious issue with the impeller. The impeller is without any doubt one of the most crucial parts in taking the water out of your basement. This sound can occur either if there is something that is blocking the impeller or if your sump pump needs a new impeller.

Sump Pump Grinding Sound Solution

When you hear a grinding sound coming out of your underground basin, then you don’t have to worry. First, you will have to open the lid of the pit to see for any blocking agent. If there is any, simply take the water out of the sink and make it clean. If it is not the case, then buckle up as you will have to get a new impeller. You will have to take the sump pump out of the pit, change the impeller with the help of a wrench, and place the sump pump back into the underground basin.
