Shower pumps are incredibly useful for improving water pressure in your shower, especially in homes with low water pressure or gravity-fed systems. These pumps ensure that your shower provides the pressure you need for a comfortable experience. However, like any mechanical device, shower pumps can encounter issues over time. In this blog, we’ll explore the common problems with shower pumps in the UK and how to solve them, so you can get back to enjoying your shower.
1. Loss of Water Pressure
One of the most common complaints when it comes to shower pumps is a loss of water pressure. If your shower pump is working but the water pressure is weak, it could be due to a number of issues.
Possible Causes:
Blockages in the Pipework: Over time, debris, limescale, or mineral build-up can block the pipes feeding into the pump. This restricts water flow and reduces the pressure.
Incorrect Pump Installation: If the pump was installed incorrectly or isn’t suitable for your system, it might not deliver the expected water pressure.
Pump Failure: A worn-out or failing pump can also result in poor water pressure.
Solutions:
Check for any visible blockages in the pipework and clear them if necessary. You might need to have the pipes flushed if the issue is severe.
Make sure your pump is the correct type and size for your system. An undersized pump won’t generate the needed pressure.
If the pump is old or damaged, it may need to be replaced.
2. Noisy Shower Pump
A noisy shower pump can be a real nuisance, but it’s often a sign that something’s not quite right. A working pump should be relatively quiet, so loud noises could indicate an issue that needs attention.
Possible Causes:
Air in the System: If there’s air trapped in the pipes or pump, it can cause the pump to make loud noises or even vibrate.
Vibration: Sometimes, the pump may not be installed securely, causing it to vibrate and make noise.
Worn or Faulty Components: Over time, the motor or bearings within the pump can wear out, leading to rattling or grinding noises.
Solutions:
Bleed the system to remove any airlocks. You can do this by turning off the water supply, running the shower to let the air escape, and then turning the water back on.
Ensure the pump is properly secured. If it’s loose, it can vibrate and make noise. Tighten any screws or brackets that hold the pump in place.
If the noise persists and seems to come from the pump itself, it might be a sign of wear and tear, requiring a professional assessment.
3. Shower Pump Not Switching On
If your shower pump isn’t turning on at all, it can be frustrating. Fortunately, there are several common reasons for this, many of which are easy to check.
Possible Causes:
Power Supply Issues: The pump relies on electricity, so if there’s an issue with the power supply, it won’t work.
Pressure Switch Malfunction: Shower pumps often have a pressure switch that activates the pump when water flow is detected. If this switch is faulty, it may prevent the pump from turning on.
Blown Fuse or Tripped Circuit: The fuse connected to the pump might blow, or the circuit could trip, especially if there’s an electrical fault.
Solutions:
First, check that the pump is plugged in and that the power supply is working. Try switching the circuit breaker off and on to reset it.
If the pressure switch is malfunctioning, it may need replacing. A professional plumber or electrician can help diagnose and fix this.
Check the fuse and replace it if necessary. If the fuse blows repeatedly, there may be an underlying electrical fault that needs addressing.
4. Pump Losing Prime
A shower pump can lose its prime (the airlock) and fail to function properly. When this happens, the pump might run but not move any water, or it might make a strange noise.
Possible Causes:
Airlocks in the System: Air can get trapped in the pump, preventing it from working effectively. This is especially common after a new installation or when the pump has been turned off for a while.
Water Supply Problems: If the water supply feeding the pump runs low or is inconsistent, the pump can lose its prime.
Solutions:
To prime the pump, you may need to bleed the system. Run the pump with the water supply off briefly, and then switch it on again. This helps remove air from the pump.
Ensure the water supply to the pump is constant and doesn’t dip below the minimum level required by the pump. If the problem continues, you might need to adjust the installation or check for leaks.
5. Pump Leaks
Leaks can occur in any part of your shower pump system, from the pump unit itself to the pipework and connections. Even a small leak can lead to water wastage and poor performance.
Possible Causes:
Damaged Seals: The seals inside the pump can degrade over time, causing water to leak.
Loose Connections: If any of the pipes or connections are loose, water can leak out of the system.
Corrosion: Over time, metal parts of the pump can corrode, leading to leaks.
Solutions:
Inspect all seals and gaskets for wear and replace them if needed. A professional plumber can do this for you if you’re unsure.
Check the connections and tighten any loose fittings.
If corrosion is present, it may be time to replace parts of the pump or the pump itself, depending on the severity of the damage.
6. Overheating
In some cases, shower pumps can overheat, particularly if they’re running for extended periods or if there’s an issue with the motor.
Possible Causes:
Continuous Running: If the pump runs for too long without a break, it can overheat.
Clogged Pump Filter: A clogged filter can cause the pump to overheat due to restricted water flow.
Faulty Motor: Over time, the motor can wear out, causing overheating or failure.
Solutions:
Make sure the pump is not running continuously for long periods. If you’re using the pump for extended showers, consider giving it a break between uses.
Clean the pump filter regularly to ensure proper water flow.
If the pump continues to overheat, it may be a sign of a failing motor that needs replacing.
Conclusion
Shower pumps are an essential part of many homes in the UK, helping to boost water pressure and enhance your showering experience. However, as with any mechanical system, they can develop issues over time.
