Hello I am in the process of draining my pool for the new liner to be installed next week.. my question is I am down to the last 1 or 2 feet and had to shut the pump off to gather up all the leaves pine needles etc before sucking the rest out and now my pump wont prime and suck out the last bit (plus rain water from yesterday)..I tried filling the pump basin with water, nothing happens, I try running the pump in normal position to get water moving and nothing.. I know the pump works do I need to send water down the skimmer side to prime the pump? why is nothing going to "waste" ...Thanks folks!!
