I have dead algae in the bottom of my pool that I want to vacuum to waste and I just used a flock. Everything worked and the junk is at the bottom of the pool. I set my multi port valve to waste, hook up my hose and vacuum as normal. I notice that water is going out the waste line as it should, but it also goes through the return back into the pool. I only have 1 return and the junk is getting back into the pool because of this. I marked this as urgent as I need to vacuum fully before the flock stops working.
i have a ball valve on the hose going to the return and I tried closing it so no water would go through. The water then started to seep through the plastic site just before the waste port.
what are the exact steps I should be doing in this situation?
thanks ahead of time!
