How is the system maintained?

As a general rule filters should be thoroughly cleaned once a year and we recommend a full 'flushing' of the system every three years. A treatment with an anti-algicide such as sprayguard is also recommended. A correctly designed harvesting system overflows on a regular basis to remove floating matter and the pumps are very reliable. Maintenance should only be carried out by qualified or experiences personnel. Combined harvesters have their own teams available year round to keep systems working efficiently.
