Commonly asked questions

  • 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.

    Please see our caring for your shower guide for more information.
  • Which shower model do I have?

    The majority of Aqualisa showers do not have a name or model written on them but if you have an Aqualisa electric shower, the model will be inscribed on the front cover or possibly on the Aqualisa badge.
     
    Alternatively you can contact our Customer Care team by e-mail and attach some photographs of the product for us to identify. Otherwise please telephone 01959 560010 and speak to an agent.
     

  • 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. 

  • 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.
  • 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.

  • 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.

  • 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.
