umm.. well we have done that on several occations, which then had led to not that much rain, then we had to add water from the hose.. I was curious for a more sophisticated solution. Dont get me wrong the backwashing works fine.
Maybe expain the bib hose thing... you may be right about not knowing about somehting on there.. our pool installer was a true "jackass and also a dumbass" and never showed us even one thing about the pool or pumps or anything.. had to just figure it out on my own.
