How to Fix a Noisy Shower Pump (Expert Guide)
Noise is one of the most common complaints about older shower pumps. The banging. The vibrating. It may provide a fantastic shower, but if someone is showering while you sleep, the noise is going to drive you nuts.
While you will never find a solution to completely silence your shower pump, there are a range of things you can do to ensure your pump runs quietly without compromising on performance.
If you can't afford to buy a new, higher-quality shower pump, take a look at the tips below.
Check Surrounding Pipes
While each shower pump will be tested to ensure noise reduction, it’s always a good idea to do a pipe inspection to ensure all surrounding pipes are well supported and completely secure. Loose pipes tend to exacerbate vibrations and can make the noise emitted by the shower pump to become unbearable.
Our advice is to support all the pipework and flexible hoses with pipe clips and even wrap the pipes in a little foam rubber for extra sound insulation.
Buy a Noise-Reducing Pad
It’s a simple and obvious tip but one that is often overlooked by plumbers and contractors. Particularly useful if your pump is resting on wooden flooring, a noise-reducing pad or anti-vibration pad can be used to soak up all the vibrations created by a shower pump. A cheap and effective investment.

Mount the Pump on a Paving Slab
If you can’t afford mounting pads, a paving slab or breeze block are good pump mounting alternatives. While they’re not specifically designed to be anti-vibration noise reducing, they are pretty good at soaking up vibrations and reducing the noise emitted by the pump.
Upgrade Your Pump
Most shower pumps will come with a long-term guarantee, especially if you’re purchasing a Stuart Turner, Grundfos or Salamander shower pump. It’s worth checking your warranty. If the noise is gradually getting worse or is starting to make a high pitched whine, your warranty provider may replace your pump for free.
Change Pump Location
The most popular place to install a shower pump is within an airing cupboard. This can be a great place both well out of sight and out of harm’s way. The problem with an airing cupboard is that they tend to be acoustic and can amplify the smallest of noises from vibrations. Consider having your shower pump relocated to an inaudible location.
Build a Sound Insulating Foam Box
Although this won’t stop the vibration noises travelling through the floorboards, it will insulate you from the general hum and buzzing noises that the shower pump will generate. One thing to keep in mind is not to build the foam box too tightly around the shower pump. Building the box too tightly will cause the motor to overheat. It may be an idea to fit the box with air vents.
Seal the Cupboard
If you’re stuck with the airing cupboard as your only installation option, it may be a good idea to seal the door with draft strips. It may seem counter-intuitive, but try not to ‘over seal’ the cupboard. If the room is completely sealed, it may heat up and cause the shower pump to trip out. Draft strips offer a balance between shower pump noise reduction and ensuring the cupboard is ventilated.
Replace the Shower Pump
If the noise is coming from within the pump, then no matter how you mount or re-install the pump the noise will remain. In this case, your issue is probably worn out parts and it’s probably time to replace the pump. If the pump is under five years old, then you should check your warranty as you could be able to claim a free replacement.
Which shower pumps are the quietest?
Although you should expect some level of noise from your shower pump, some models ARE quieter than others. This is all down to the brand that you choose and the quality of the product. Many of the top shower pump manufacturers have taken numerous steps to resolve this issue for their customers, using high-quality materials that offer a quieter vibration when in use.
