The Different Noises Produced by Water Pumps
Water pumps can be very noisy machines depending on the model and type, and where it is installed. If it is a submersible unit installed in a well, like many models, you will normally just hear the pump control relay (this switches the pump off or on) clicking or the water rushing as it enters the building pipes or water pressure tank. However, you may hear other noises coming from the pump, and these are caused by a wide range of things and factors.
These are the other noises produced by water pumps:
* You can hear a quiet hum instead of a loud, rattling noise if the pump has lost prime (has air instead of water) and gets it (contains water) back afterwards. This is an indication that your pump is close to breaking, and so you might want to change how you use it.
* If you have the type of pump that can be installed indoors, then you might hear loud vibrations wherever you are in the house or building. Vibrations are transmitted to different parts of a building through the air and by direct contact with the pipes, walls, and/or the floor.
To remedy this problem, it is best to enclose the pump in a utility room with sound control insulation. You can also use foam or rubber mounts to secure pipes at the pump to the nearest building framing. The switch to a quieter pump is another good option. Covering or surrounding the pump with fibreglass insulation, however, is not advised, as it encourages the growth of mould due to condensation.
* Noise may also be caused by pump parts or mounts being loose or a bad bearing on the motor/impeller.
* The clicking of the control switch, as mentioned above, is a normal sound produced when you switch the pump on or off. A humming sound coming from the same part, on the other hand, may be an indication of a risk control burn-up and a stuck relay.
* ‘Thunk’ or ‘clunk’ noises can also be heard around the piping, tank, or pump control switches. If the sound came from the water pressure tank controls or the water pressure tank, especially if the pump has just been switched on, then the pump relay switch is failing. This, in turn, is caused by a failing check valve. A loose pipe also causes ‘thunk’ or ‘clunk’ noises.
Pumps may be noisy machines, but the noise they produce can be lessened or even eliminated with proper troubleshooting. To save time in troubleshooting and sorting out pump noise, you can hire the assistance of a highly-reputed plumber.
