1) Is the Badu Eco Wise cartridge filter available in the US and do you have experience of it? (The Badu is distributed by Spec Pumps in South Africa.)
2) If yes, I want to know if there is a better way to clean this filter besides just hosing it with the garden hose, eg. By soaking in a large bucket for a period with a type of detergent/washing powder added to the water? Mine is the Eco Wise-2.
3) Must it be hosed just on the outside, or should I use a 90 degree nozzle that can reach down the inside then wash from the inside, pressure going outwards?
4) The local agent says "No" to my question of soaking in detergent, but I have the feeling they want to rather sell me a new filter which is quite expensive.
