Repairing or replacing a failing shower pump
At a glance
- Noisy bearings or a failing motor are rarely worth repairing on an older pump; the cost of parts and labour can approach a new unit's price.
- A pump losing prime or cutting out intermittently sometimes points to an air lock or failing non-return valve rather than the pump itself, which is worth diagnosing before condemning it.

Questions we get asked
How long do shower pumps typically last?
Domestic pumps generally have a working life measured in years rather than decades, and usage intensity affects that considerably.
Can a pump be upsized to improve a weak shower?
Often yes, provided the pipework feeding and leaving it, and the shower valve itself, can handle the higher flow rate.
How to choose
Point 1
Noisy bearings or a failing motor are rarely worth repairing on an older pump; the cost of parts and labour can approach a new unit's price.
Point 2
A pump losing prime or cutting out intermittently sometimes points to an air lock or failing non-return valve rather than the pump itself, which is worth diagnosing before condemning it.
Point 3
Replacing with a higher-output pump than the original can improve performance, but the supply pipework and shower valve need to be rated to handle the extra flow.
