In the last article we discussed how easy it is for your pond pump intake to become blocked with leaves mud and other pond detritus. When you have cleaned the intake and the pump still does not work what do you do?

The filter in your pump might have become blocked, these can be replaced for a new filter on some models and if not it can be cleaned thoroughly. The next thing to look at is whether the spray holes have become blocked, this may be the case if you live in hard water area. Calcium build up can block the holes over time so you can clean the nozzle it a de-calcifying solution (commonly used to decalcify your kettle or shower head).

If this does not work and you have a lot of patience you could always use a pin or another sharp implement to further remove the build-up from the holes. Lastly, and this is the worst scenario, the internal workings of the pump or the pump motor may be faulty. In cases like this it is commonly easier and cheaper to buy a new pump than to get your old one repaired.
