Bleeding an Aqualisa shower pump involves getting rid of the air trapped in the pump system. Trapped air can significantly reduce the pump’s performance and cause it to operate noisily. Here’s a step-by-step guide to bleeding an Aqualisa shower pump:
- Power off: Start by switching off the power supply to the pump. Safety should be your first concern when dealing with electrical appliances. You should also turn off the water supply.
- Identify bleed points: On your Aqualisa pump, look for the bleed screws. These are typically located on the top of the pump. There might be two of them – one for each impeller.
- Prepare a container: Before you unscrew the bleed screws, prepare a container or basin to catch the water that might flow out when you open the screws.
- Bleed the pump: Carefully loosen the bleed screws. You don’t need to fully unscrew them, just enough to allow trapped air to escape. You should hear a hissing sound as the air releases.
- Wait: Be patient. Allow the trapped air to escape completely. Water will start flowing out of the bleed screws once the air has escaped.
- Tighten the screws: Once the water flows continuously without spurting, all the air has escaped. Now you can tighten the bleed screws again. Be careful not to overtighten as you could damage the screws or pump casing.
- Restore power and water supply: Once the screws are secured, you can turn the water supply back on, followed by the power.
- Check the operation: Finally, run the shower system to verify that the pump is operating quietly and efficiently. If it’s still noisy or inefficient, you may need to repeat the bleeding process or seek professional help.
Remember, if you are uncertain about performing this task, it’s always best to consult with a professional. Also, before attempting to bleed your Aqualisa shower pump, make sure to refer to the user manual provided by the manufacturer as instructions can vary based on the model and type of the pump.
