New member here with something of an embarasing question.
I have owned this used above ground 18' pool for about 10 years now. never had any major issues that I could not resolve. Anyway, while replacing the divirter valve and spring I got to realizing that I never used 2 of the 6 control positions on the valve. I know what the filter position is obviously as well as the backwash and waste positions. I am assuming that the Closed position will stop all water flow either way thru the filter. Not sure of the need but it is there none-the-less. the two I am currious about is the Rinse and Recirculate positions. I have never used these and do not know what they are for. The filter in question is a Sparco brand filter which I believe is a re-badged Pentair Tagelus which is what the parts cross referenced to. Here is a link to the filter in question http://www.poolpartsonline.com/p-642-pe ... lters.aspx Any help with this puzzle and what I should be doing with them would be greatly appreciated.
