Frequently Asked Questions & Answers
When does a ceramic filter element need cleaning?
Once the flow out of the filter becomes noticeably less than normal.
How do I clean a candle?
Use a scouring pad (similar to 3M 'Scotchbrite'). Ensure that the end of the plastic mount does not come into contact with unfiltered water and dirty hands. Rubber gloves are always recommended to be used during cleaning and NEVER use soap or detergents!
My filter candle blocks up too regularly, what can I do about it?
In some water conditions, there is so much particulate or turbidity in the supply water that the candle becomes blocked much more quickly than in normal conditions. In these circumstances, it is beneficial to use a pre-filter upstream of the ceramic candle; - this prevents the candle from becoming blocked too quickly, minimises cleaning and so extends the life of the ceramic filter.
When does a ceramic filter element need replacing?

Ceramic Only: Once cleaning fails to restore the flow. Although, each individual candle does have a recommended capacity when used in normal conditions. The capacity for a specific element is quoted in within the section dedicated to each filter element's construction and performance.

Combination Filter Elements: In dual functional systems cleaning the ceramic will not extend the life of the internal material. For example: the 'life' of the extruded carbon block in the Ultracarb filter elements is determined by the concentrations of chlorine and/or volatile organic compounds in the supply water. In most cases, the filter element should be replaced after 6-12 months of daily use or 3,800 litres. The particulate and turbidity concentration in the supply water governs the life of the ceramic, which may exceed or not achieve the capacity of the carbon insert. Whichever point is reached first governs when the filter element requires replacing - the six months usage or the ceramic becoming blocked to the extent where cleaning does not restore the flow.
