Why isn't my power shower working properly?

 A power shower is a great way to enjoy a strong, invigorating flow of water, especially in homes where water pressure is naturally low. But when your power shower starts to malfunction or stops working altogether, it can be incredibly frustrating. If you're wondering why your power shower isn't working properly, there are a number of potential causes, some easy to fix, others that may require professional attention.

Low water pressure or flow problems

While power showers are designed to increase water pressure, they still rely on a steady flow from hot and cold water tanks. A problem with either of these systems, such as a blocked pipe or a closed valve, can reduce the performance of your shower. Check that your water tanks are full and that the valves that feed your shower pump are open and free from blockages.

Shower Pump Faulty

The heart of a power shower is the pump, which increases the water pressure. If your shower suddenly loses pressure or stops delivering water altogether, the cause could be a malfunctioning pump. Pumps can wear out over time or become blocked, especially after maintenance or changes to the plumbing system. In some cases, the pump may need to be reset, repaired, or replaced.

Electrical Problems

Since power showers use electricity to run the pump, the cause could be an electrical fault. Check that the power to the shower is working: check the circuit breaker or fuse box to see if anything has tripped. If you are not comfortable working with electrical components, it is advisable to call a qualified electrician to inspect the system safely.

Thermostat or temperature problems

If your power shower is producing water that is too hot, too cold, or at variable temperatures, it could be a thermostat problem. Most power showers have built-in temperature controls, and if this is faulty, the thermostatic cartridge or mixing valve may need to be replaced. Also, make sure that the hot water supply from the tank is consistent and that the cold water supply is working properly.

Vents in the system

A vent occurs when air becomes trapped in the pipework, interrupting the flow of water. This is especially common in homes with gravity-fed systems. If your shower is making strange noises or the water isn't flowing smoothly, you may have an air lock. Bleeding the system or using a hose to force water through the pipes can often solve the problem.
