Few things disappoint more than a weak shower, so if you think your electric shower isn't as powerful as it once was, or your electric shower isn't working at all, then there a few things you should check before taking drastic action:
Check the Shower Hose for Leaks
If the shower hose is leaking, not all of the water will be making its way to the shower head and water pressure will be leaking out. The image below shows a possible sign of a leaking shower hose.
The shower hose transports the water from your shower unit to the shower head. On rare occasions, the inner rubber hose can split which will affect the power of the water coming out of the shower head. If you disconnect the shower hose, and fill it with water, you can test for a leak in the structure of the hose.
Secondly, the O-Rings between the hose and shower unit and the hose and the shower head can become worn or damaged.
If any of the above applies to you, you should replace the entire hose or the O-Rings.
Clean the Shower Head
Depending on the type of water that is supplied to your house, you may be victim to the build up of limescale. This will restrict the flow of water going through your shower. In worse cases it will block entire nozzles, blocking the water from being able to exit the shower head.
You can wipe the nozzles with a damp cloth and this should dislodge most of the limescale. Anything more persistent may need more work, using a toothpick for example. You can also soak your shower head in vinegar to counteract any limescale.
Once cleaned, you should once more be able to experience the wonders of a strong, fully drenching shower.
Replace the Shower Head
Some electric shower are fitted with shower heads that restrict the flow of water. The idea behind this is to help you use less water. However, rightly, you may feel dismayed by if it negatively impacts your shower experience.
It is very easy to fix this: simply unscrew your current shower head and replace it with one that does not restrict the flow. However, it is always important to be mindful about how much water you are using from a sustainability standpoint.
If you've done all of the above and your pressure is still too low you may need to take further action by installing a shower pump or accumulator tank to permanently increase the pressure to your electric shower. There are a few things to consider here:
- Most electric showers need a minimum of 1 Bar to operate,
- It is illegal in the UK to pull more than 12 L/min from the mains supply into your household. If you want to pump higher than 12 L/min more than that, you need to put a break tank in between the mains inlet and your pump,
- Electric showers can only heat up a certain amount of water, so you need to check your shower's power rating before you decide on your pump. If your pump is too powerful for your shower, you might not end up with the desired outcome.
Install a Shower Pump
The quickest, cheapest and easiest fix is to install a pump somewhere between the mains and the shower you want to fix.
If the rest of your home has good pressure, but you simply cannot get your electric shower to work consistently, you may want to consider a shower pump specifically for your electric shower. If this sounds like a good idea to you, check out our Electric Shower Compatible Shower Pumps.
Install a Mains Inlet Booster Pump
A mains inlet booster pump is a type of shower pump designed to support your entire home. This can be useful when every single outlet in your home has poor water pressure.

Install an Accumulator Tank
An accumulator tank is a whole-house solution to boosting your water pressure. This solution is significantly more expensive than a normal shower pump. It is also overkill for a single electric shower, but if you live in a medium to large sized home or want to use more water than what the mains inlet can supply, it may be a considerations for you.
Overhaul your Plumbing System
The final and most drastic fix is to overhaul you entire plumbing system. This is only really recommended for older properties. Your plumber could replace your pipework to make use of newer technologies and boost the pressure throughout your home.
