    Question Does water flow effect a SWG?

    I have a variable speed pump. I run my pump at 2500RPM for 2 hours/day and 1000RPM for 4 hours/day for a total of 6 hours. My question is this, does the SWG produce more chlorine at the higher water flow rates than it does at the lower water flow rates? Thanks.

    No, the output is independent of the flow rate. You just need to be sure that the flow is sufficient to satisfy the flow switch on the SWG. 1000 rpm isn't quite enough for my system. I have to run at 1250 or more in order to generate chlorine.
