Frequently asked questions

Search Can I improve my shower pressure?

For gravity fed water systems you can add a pump to the system. This does not work for other water systems.

Search Can two showers run simultaneously on one water system tank?

We would not advise to have two showers running at the same time from a water system tank as it can cause the hot and cold water tanks to run down very quickly.

Search Does Aqualisa have a taps range?

Aqualisa has a tap range which can be found here.

Search Does the pumped processor unit need changing on my digital shower when changing from a low pressure system to a high pressure system?

The pumped processor unit will need to be changed to the standard processor unit. This is due to the pumped unit only being to withold a maximum of 1bar pressure and having the pump built into the unit. The standard processor unit is designed to take a minimum of 1bar pressure on high pressure water systems. Connecting a pumped processor unit to a high pressure water system will cause a fault with the unit and invalidate any warranty that is on the unit.

Search How can I descale my shower head?

We advise to descale the shower head by soaking the component in warm water and white vinegar for approx. 20 minutes.

Search How can I fix a dripping shower head?

We would advise to check for any restrictions in the shower head or hose, by this we mean kinks or twists in the hose or lime scale blockages in the spray plate of the shower head, this can be cleaned by soaking the component in warm water and white vinegar for approx. 20 minutes. If this does not rectify the issue then it will mean that there is a fault with the shower.

Search How can I fix a leak from my electric shower where the hose connects?

If the leak is coming from a small hole behind the hose connection, this will mean that the Pressure Relief Device (PRD) has activated due to a blockage or restriction within the shower head. The PRD will need to be replaced and We would advise to check for any restrictions in the shower head or hose, by this we mean kinks or twists in the hose or lime scale blockages in the spray plate of the shower head, this can be cleaned by soaking the component in warm water and white vinegar for approx. 20 minutes.

Search How do I change the handset holder on my exposed smart / digital shower?

You will need to isolate the power and water to the shower, disconnect the data cable at the processor unit / Quartz™ smart valve and then disconnect the black push fit 90° elbow located directly above the shower, fitted to the shower’s down pipe. Remove the fixings that hold the shower to the wall and carefully lower the shower down from the ceiling. Pull the 10m data cable through into the bathroom. Once the cable is in the room with you, you can slide the old holder off the top of the rail and over the data cable, and reverse to fit the new holder. As this is a technical job we usually recommend an Aqualisa service engineer carries out this work.

Search How do I clear an air lock?

If your shower struggles to produce water (especially hot water) and spits or splutters in use, the most common cause is an air lock. Air locks normally occur within the pipe-work of the hot supply and can develop over time or occur all of a sudden. You may find that the air lock only affects the shower and all your other appliances are fine - this would be because the shower should have its own dedicated supplies and the restriction has developed within this pipe-work. 


There is a simple procedure you can try, using the shower to clear the air from the pipe work:

  • Remove the shower head from the end of the flexible hose or fixed arm,

  • Start the shower on the coldest setting,

  • Slowly turn the temperature dial towards hot,

  • If at any point the shower begins to spit or splutter then stop turning the dial and wait for the air to clear before continuing towards the hot,

  • You may have to repeat this process a few times to clear the air entirely but afterwards the hot and cold flow should be the same. 


The idea of this exercise is to use the working supply to create suction down the pipe-work which will then siphon the air out. 

If you find you have recurring air locks you may need to consult a plumber, or if the air will not clear and the flow continues to splutter then you may be experiencing cavitation, draw down or possibly an air leak.

Search How do I disconnect my shower head from the fixed arm or flexible hose?

Aqualisa fixed shower heads have a basic threaded connection and simply unscrew from the fixed arm. The same is true for most of the flexible head kits but some models have an ‘anti-twist’ connection to protect the shower hose from becoming kinked due to the head swivelling freely whilst it is connected to the hose.
Listed below are the various shower heads which have ‘anti-twist’ connections and instructions on how to disconnect them from the flexible hose.
Axis head-kit
If you look at the base of the handle on the shower head (just above where the hose connects) you will see there is a groove cut into the handset and inside this groove there is a horseshoe shaped clip. Remove the clip from the base of the handle by gently pulling each end apart and sliding the clip free from its seating. Once the clip has been removed, the hose connector will slide free from the handset and you can unscrew the fitting from the end of the hose.
Harmony head-kit
The Harmony shower head has a button at the base of the handle on the underside of the handset. To remove the flexible hose you must hold this button down and unscrew the handset from the hose connection.
Opto head-kit
If you look at the base of the handle on the shower head (just above where the hose connects), you will see a thin rectangular slot on the front and back of the handle which should be dark grey in colour. If you press down on the slot on the back of the handset - the hose connector will be released and should slide free from the handset, you can then unscrew the fitting from the end of the hose. 

Search How do I maintain/clean my Aqualisa shower?

Aqualisa products are very low maintenance and there is very little for you to do to keep them in good working order.


If you live in a hard water area, which is prone to scale and calcification, you may need to descale the shower head every few months (or as and when needed). We have found that an effective way to do this is to soak  the head in a mixture of water and white vinegar, then the flakes of scale should rinse away. To avoid rapid scale build up, we advise that after use you tilt the shower head at an angle, which will allow any excess water to drain away.


When cleaning an Aqualisa product, we advise that you use warm soapy water or non-abrasive bathroom cleaning products.

Search How to replace a digital pumped processor with a standard (unpumped) processor

To replace a digital pumped outlet with a standard outlet, you will need to isolate the water and the power to the shower and remove the pumped processor unit. You will then need to adjust the outlet pipework for it to be in the correct location to fit on to the outlet connection on the standard processor unit. Once the pipe work and cables have been connected, turn the power and water back on to the shower.

Search If I have two smart showers operated by two separate wireless remotes, will the two systems interfere with one another?

No, the remotes signal should not interefere with one another. 

Search What are the differences between 8.5kW, 9.5kW and 10.5kW electric showers?

The bigger the engine size the quicker the water heats up.

Search What are the differences between Midas 110 and Midas 220?

The Midas 110 has plastic control knobs and a standard shaped bar valve. It also has slightly lower flow rates to the Midas 220. The Midas 220 has metal control knobs, a different shaped bar valve and also has a different style head kit to the Midas 110.

Search What are the differences between Quartz and Visage smart showers?

The main differences between these two models is the visual design of the controls and the head kits. Also, the Quartz single outlet model has a boost feature whereas the Visage single outlet does not have a boost feature.

Search What can I do about a noisy shower pump?

We would advise to check for an air lock within the pipe work to begin with as this can cause the pump to become noisy. A step by step guide to clear an air lock is available in the FAQs.

Search What factors influence flow rate?

The water system that the property is on, size of the pipe work leading up to the shower connections and also if any other outlets are used within the property at the same time as the shower.

Search What is an air leak?

An air leak is where there is a leak somewhere on the supply to the shower and while it is in use the air is sucked in through this gap. If you think you are experiencing this, please contact your plumber.

Search What is cavitation?

Cavitation means that air bubbles are being created within the pipe-work and are being introduced to the shower which is affecting the flow. This is normally caused by the hot water temperature being set too high and we advise that it is set to no higher than 65ºC.

Search What is covered under an Aqualisa warranty?

All parts and labour will be covered under Aqualisa Warranty.

Search What is draw-down?

Draw down occurs when there are restrictions in the shower's hot and cold supplies, such as scale. These restrictions can cause an amount of suction in the pipe-work when the shower is in use, which then sucks air down the open vent pipe. The open vent pipe is the pipe which rises from the top of the hot water cylinder and hangs over the cold water tank. There is a simple method of testing for draw-down, you simply run the shower and then hold a glass of water up to the end of the open vent pipe. If the water is sucked down the pipe then draw-down is occurring, in which case please contact your plumber.

Search What is the estimated delivery time for Aqualisa products?

We advise to allow 3-5 working days for delivery.

Search What is the guarantee period on processors?

Search Why has my shower pressure reduced?

This could be caused by a blockage within the shower head or hose. We would advise to check for any restrictions in the shower head or hose, by this we mean kinks or twists in the hose or lime scale blockages in the spray plate of the shower head, this can be cleaned by soaking the component in warm water and white vinegar for approx. 20 minutes. If you are on a gravity fed water system with a cold water tank, we would advise to check for an air lock. Further steps on how to clear your air lock can be found in these FAQs.

Search Why won't my (Aquastream) pump turn off?

If a brand new shower, check that the on/off control knob is not fitted upside down. Check that the loom assembly is fitted correctly over the cartridge and that there are no signs of damage to the micro switch or the switches getting stuck down. If these are all ok then it will mean that the loom assembly will require replacing.
