Shower Pumps

Air can build up in a pump installation over time and when not used regularly. It can cause a variety of issues that are often blamed on the pump. However, a simple air test can clear out your installation and solve the issue - at no extra cost!

  • pump pulsing
  • pump running on
  • excessive noise
  • temperature fluctuation

If your installation is suffering with any of the above, it would be worth running the air test to eliminate air as a fault cause.
