My pond filter or pond pump has failed?

Pond pumps and filters require regular maintenance and we would advise you to refer to the manufacturer's instructions for how to do this and any troubleshooting recommendations. 

For pond pumps and filters please ensure that you have first checked the power supply is working without issues (no tripped switches etc.) and with the power off manually inspect the full length of the cable from the power source to the appliance, it is not uncommon for wildlife to damage the cable and for this to be the issue. 

For pumps please inspect the impeller and chamber ensuring there is no damage/blockages within this area and cleaning/removing any debris and check the impeller can move freely. If the pump is over 12 months old then a consideration would be to replace the impeller these are a consumable part of the pump and not covered by the warranty. 


For filters we advise that after checking your power supply that you safely check the lamp is working by the instructions provided in the instruction manual, all filters have safety mechanisms in place to ensure you do not look directly at the lamp when it is on due to harmful UV light. In most cases it is only possible to check this at night any indicators are usually barely visible so only noticeable in the dark. In the event the UV lamp is not working, the first step is to change the lamp - lamps are a consumable part of the filter and not covered by any warranty. 


If your filter is tripping your electrics, then the most likely cause of this is water getting into the electrics - this is commonly experienced after changing a lamp or O rings and can be due to the quartz tube either being damaged in the process or O rings damaged or unseated. The other reason can be your pump flow rate being too high a flow rate and exceeding the maximum flow rate for your gravity-fed filter. In the event this occurs you should fully drain and then dry out the product for 48 hours and re-assemble the unit ensuring that all O rings are in place and undamaged, these would need to be replaced in the event of any damage being found, and the quartz should be inspected and fitted firmly and again replaced in the event of any damage being found and then re-test the unit.
