How to Reduce Noise Coming From Your Shower Pump

The Quietest Shower Pumps on the Market


Introduction

Shower pumps are a common feature in many homes that allow you to get a good water flow at the shower head.  However, the demand for shower pumps to be powerful and quiet, yet smaller for fitment presents a problem. Shower pumps are more likely to fail or break.

But how do you know that it’s actually the shower pump that has failed? What are the most common shower pump problems? And, what are the solutions to these shower pump issues?

To help you identify if it’s the shower pump that is causing the problem, and hopefully fix the issue, we’ve spoken to our in-house engineers. With over 40 years of experience, they’ve helpfully listed the most common shower pump problems and how to deal with them.

Basic Checks

Before you panic, call a plumber and buy a brand new shower pump, we advise performing a few basic checks. More often than not, shower pump issues are down to a tripped wire. So if your pump isn’t working at all, check the below.

- Check that the power to the pump is turned on.

- Check that the power supplying the pump has not tripped out (this may be due to the pump running dry).

- Check that none of the inlet or outlet pipes are kinked or blocked. This could stop water from getting through to the pump.

- Try resetting the pump by switching off the power for a few seconds.

My Shower Pump is Making Too Much Noise

One of the most complained about shower pump problems is noise. Ranging from a constant rattle to loud bangs and even excessive vibrations, this is often due to the way the shower pump has been installed.

Solution

It’s important to ensure that anti-vibration feet are fitted, where supplied, and that the pump is on a firm platform. Try mounting the shower pump onto a concrete block, which will help absorb the vibrations and in turn, reduce the noise. You should also ensure that any pipework on either side of the pump is properly supported by clips, and bends in flexible hoses are kept to a minimum.

My Shower Pump is Pulsing

One complaint we often hear is how the shower pump is pulsing. More often that not, this isn’t due to the pump, but is actually due to some form of blockage in the plumbing system. The blockage will obviously cause the flow rate to decrease and the pump will start and stop in a pulsing manner.

Solution

An exact solution can be hard to pinpoint as the blockage could be at various points in the plumbing system. Make sure you check for limescale in the shower head or a collapsed hose causing back pressure at the pump. You can check this by removing the head and then the hose in turn, to see if the pump then runs smoothly. If it still doesn’t, then check any filters on the pump itself. If you are still having problems, then we would advise that you contact a plumber to inspect your system.

My Shower Pump has Too Much Flow

You might think that of all the shower pump issues to have, too much flow would be one of the better ones; yet too much flow can lead to several problems.

Firstly, you could be damaging the plumbing system. If the flow is noticeably too strong, this could be having an impact on the rest of the system.

Secondly, you could be wasting a lot of water. This could add serious £££ on your water bill.

Finally, you could be using stored hot water too fast. This may lead to severely angry members of your household. So, as you can imagine, it’s important to have the appropriate flow rate.

Solution

The best way to tackle this is to close the isolator valves on the outlet side of the pump down slightly - don’t restrict the flow on the inlet side of the pump.

My Pump Keeps Turning Itself Off

If your pump keeps turning itself off, then this may be due to the pump running dry. The majority of pumps have dry run protection, which cuts in to protect them from damage if the water supply is interrupted. If this protection kicks in, the pump will stop.

Solution

You need to turn off the mains power to the pump for a few seconds to reset the pump (there will usually be an isolator switch or fused spur). You then need to open and close the taps to get any air out of the system and allow the pump to return to its normal state.

My Pump is Making a Constant Humming Noise

If your pump makes a constant humming noise, it may well be that it’s jammed. There are a number of possible reasons for this. In hard water areas it could have become clogged with limescale, or the problem could be due to a fault like a broken impeller.

Solution

Unfortunately, in either of the scenarios listed above, this is probably a sign that you’ll need to replace the pump.

My Pump is Not Adding Pressure to My Shower

The most common symptom of an issue with your shower pump is the lack of pressure in your shower. If you go from an invigorating blast to a simple dribble, then you know you have an issue. Make these checks below. Please keep in mind that for some of these issues you may need to contact a plumber.

Leaking Pump

Pump seals can deteriorate over time. Perform a thorough inspection of your shower pump. Is it leaking? Do any of the seals look defective? If so, then you could be losing some of the pressure in your system.

Airlocks

Another common shower pump problem is airlock. This is where air has entered the pump and is now restricting the flow rate. To solve this issue the pump will need bleeding. Most high quality shower pumps will come with a bleed switch. This will allow you to follow the instructions in your shower pump installation guide to bleed the pump. Failing this, you may need to contact a plumber.

Blocked Pump Filters

One of the most common issues with a newly fitted shower pump is blocked pump filters. This can be due to debris getting into the pump during installation. You will need to ensure that the electric and water supply is switched off before giving the pump a thorough clean.

Frozen Pipes

Just like other pipes in your home, during a cold winter, a shower pump is likely to freeze. Take the time to warm the cold feed pipe to ensure ice doesn’t cause damage to the shower pump.

Added Note: If your shower pump is under 2 years old, then contact your pump provider. You could have the pump replaced under a warranty.

My Pump Keeps Turning Itself On and Off

One minute the pump is working fine, and the next the pump keeps turning itself off. This issue is often found in the higher end shower pumps. The pump detects a leak in the system and shuts down before causing further damage.

Solution

To fix this issue check for any visible leaks in the system. Make sure you inspect tap washers, pipe joints and connections. You may need to call a plumber to fix your leak.
