Filter media
We also stock Filter sand for our filter sets, the recommended size of sand is 0.4 to 0.8 mm, sand is supplied in 25Kg bags.
Please note the sand required is a specific grade, please do not use builders’ sand or play sand as this may block or damage your filter.
Operation
The easy to use six-way side mounted multi-port valve lets you select any of the operations with a simple lever action, the functions of the multi-port valve are filtration, waste, closed, backwash, rinse and recirculating.
Please note you must always switch your pool pump off before changing the position of the multi-port valve.
Replacing an existing filter
If you are replacing a filter that forms part of an existing system then your replacement should match the size of the existing filter.
For example if you already have a 21 inch filter and 1.0HP pump on a 20m³ pool then you would still need 21 inch filter, alternatively you would need to replace both the pump and filter with a smaller selection as per our filter size guide.
