Few things disappoint more than a weak shower, so if you think your electric shower isn't as powerful as it once was then there a few things you can check before taking drastic action:
Check the Shower Hose for Leaks
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.
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 to permanently increase the pressure in your household.
Install a Pump
The quickest and easiest fix is to install a pump somewhere between the mains and the shower you want to fix. There are a few things to consider here:
- 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 finish up with the desired outcome.
Overhaul your Plumbing System
The final and most drastic fix is to overhaul you entire plumbing system. 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.
