I have an older (early 2000's) jacuzzi sand filter with the DVK-7 multi port valve on top.
After backwashing the filter discharges some ultra fine crud back into the pool when it is set to filter again - it not a big deal, just annoying. I have read elsewhere here that the "rinse" feature on some valve setups can be used to return some water to waste just for this reason before directing to the pool.
does anyone know if this is case with this filter ?
I have also read a that one can install a 3 way diverter with a waste line on the main return to the pool to accomplish this purge function.
thanks in advance
