Just read the post on rinsing sand and was wondering how and where does the garden hose water go? If I do this cleaning do I need to set the cap dial to backwash and then the hose water will exit that way? Or am I suppose to remove the drain cap at the bottom of the sand tank?
A service tech who was at my house recently (assesing a slipping liner) told me sand should be replaced periodically. But I have no clear answer as to when I know it is time. So just to confirm, sand does not have to be replaced? If so, how would I know?
