enviro® SERVICING AREA

All Enviro® pumps are covered by a two year warranty on the pump motor. To validate this warranty, the aerator must be serviced on a yearly basis. We recommend that the consumables including the diaphragms and filter are changed at this point.

The wear and tear parts are outside the two year warranty but are covered by a year’s warranty providing they have been used correctly and not subjected to back pressure or water damage. All servicing procedures are the exact same for the alarm equivalent. 

This warranty is only valid for pumps that are used as recommended.

TROUBLESHOOTING

In the unlikely event that you are experiencing problems with your Enviro® pump, please consider the following:

Overheating causing the thermal cutout to activate Check for a clog or blockage in the airline to stop excessive back pressure overheating the pump this can also cause premature diaphragm failure. Ensure the pump is the correct size for the application. If under sized not enough air will be produced, if over sized excessive back pressure is caused, overheating the pump. If oversized, drill a small hole in the rubber elbow on the pump to allow a small amount of pressure to escape. Leave to cool and then try pump again. Pump gets hot and shuts off Torn diaphragm • Replace diaphragm by following our service instructions. If you are experiencing frequent diaphragm failures, please check for excessive back pressure in the system, as above. Pump not pushing out air Rust inside pump If the pump is getting wet inside, rust will appear causing increased friction and premature failure. If the pump is wet inside, the warranty is no longer valid. Use a wire brush to remove rust from the coils, once clean and dry, reassemble and try the pump again. Check for water, pump may have flooded • Remove pump from the system and allow to dry.• Retest pump only when completely dry.• Water damage can damage the pump beyond repair. Pump trips electric PROBLEM POSSIBLE CAUSE SOLUTION

If the guidelines above have been followed, the pump is defective and may be in need of replacement. Please contact Charles Austen Pumps Ltd on +44 (0)1932 355277.


We will need to have the air pump returned to us or a photo provided of the inside of the pump and diaphragms. This ensures that the pump is not failing due to damaged diaphragms or rust.
