Our Aqualisa power shower lacks water pressure power
Power shower is 3 yrs old and recently we have noticed a distinct lack of power in the water pressure coming through the shower head?
Is there something I could check on the pump etc which is situated in the loft? Any suggestions appreciated.

Re: Our Aqualisa power shower lacks water pressure power
More than likely you have some debris near the shower head
take an adjustible wrench( crescent or channel lock wrap a rag around the eustaceon( chrome tube coming out of shower wall srap around tube to protect the chrome hold it firmly with vicegrips or channel locks, take adjustible wrench or chanel locks and remove the chrome nut holding the shower head on to the eustaceon(turn counter cockwise be careful not to drop the tools that wil damage the tile or fiberglass
after removing showerhead
turn on shower to force and debris out and place shwoer head into stream of water to clean out any deposits the head may have some type of screen to strain the water
this should work if the flow has not incresed then there is a need to adjust the flow valve at the control
to reinstall the shower head reverse procedure
if you have any teflon tape wrap it around the threaded portion of the eustaceon

I thought this may be helpful as I have seen the same question a few times. A few days ago after my shower I turned the switch to off but the power motor was still running with water still coming out. I thought a new shower or at least an expensive call out. I looked up parts and decided to take a look and if needed replace a whole part or parts to save the call out costs.
the aqualisa is generally easy to dismantle as each part is substantial, if you are unsure look on their web site for the diagrams. This took me about 15 minutes and shower is working perfectly again and I was almost ready to replace parts or even a new shower at £400+. You will only need a cross head and a straight screwdriver.
-isolate the hot and cold supplies, and turn off the power.
- run the bathroom taps to reduce the water reassure and build up in the pipes.
- remove the front on/off dial
- remove the temperature control
- remove the front cover
- remove the black cover that clips over the main black cartridge, there is a black wire wrapped around the front holding the assembly in place so you have to remove the wire cluster that is secured on the right.
- you will see 4 torque screws holding the cartridge in place, these screws also have a straight screwdriver slot - loosen these, Be careful, there will be water and pressure still in the shower, allow this to spray out, it will gradually stop after about 30 seconds, now full remove the 4 screws.
- gently withdraw the cartridge
At the back of the cartridge is a small white water filter, check this and clear it, Mine was full of debris. Also check inside the recess as I found large lumps of grit from the water supply.
i believe the shower could not switch off as the grit and small debris had blocked the on off valve so water was still flowing and the pump therefore continued to run.
Now just assemble in he reverse order, turn the water supply and power on and the shower should work perfectly well.
After I realised that the turning off had felt different and it seemed to be spungy at the final bit of the turn off, I now realise this was the grit not allowing the mechanism to full close.
hope this helps someone.
I would suggest not enough pressure. If the hand shower is connected to the taps then pressure would be the problem as the water comes from the tank in the loft fed by gravity. Solution is a power shower.
If you have good water pressure in your home and a tank water heater and not a tank-less, as long as all jets are space equally apart you should not have pressure issues. but running straight to a jet and splitting off from that point will cause a rapid loss in pressure to the other jets because the lack of resistance. Fluid pressure is created by resistance to flow, not gpm (gallons per minute).If you flush a toilet and a faucet in another part of your home is reduced greatly you have a volume problem were the city water or well water is not supplying enough volume to your home and the multiple jets will not function correctly. Tank-less water heaters have difficult times keeping up with the demand multiple faucets create. Both problems have work arounds and fixes but it is best to get a certified plumper to install the components you would need
If your house was built before the "70's the most common reason is that the hot water trunk line to you shower has corroded shut to the point of reduced flow. It is not uncommon for this to happen on just one line. The controler its self could have an obstruction on the hot side. Replacing the internal part(s) should take care if this. Try to identify the brand of controler and research available part(s).
If its a tap refurde to, remove the head at the front of the tap and clean out the filter in front, if the houses warm water has low presure u must find ur presure redusing velve located on main cold feed to geyser and clean the cartrage out revit and ur presure must then be vine , let me know if that dosent help
I've never worked with an Aqualisa, but often times a problem like that is simply mineral build-up within the valve components. I would recommend turning the water off at the main and carefully disassembling the valve. Give it a good clean with some CLR and a toothpick. If the valve has any springs you may look into replacing them, as that is a common problem as well.
DO NOT forget to turn the water off at the main shutoff point, or you're gonna be in for the shower of your life once you take that valve out. You shouldn't need much besides a phillips screwdriver, and possibly an allen wrench and some pliers.
Your question is:
water pressure not great would a external pump help.
Depends on your situation. If you live in a house with a well pump then turn up the pressure.
If you have city water and the pressure is lacking then either install a house pump after the meter or if it is just the shower you're worried about then a booster pump on the shower line is the ticket. Be aware that useing the booster may reduce the pressure at the other faucets in the house while it's being used. The house pump will not exhibit this. You will likely need a local pro to help you with installation.
