hello, I am new to the forum, though not new to the pool school. this site and its members has helped us to go from a green swamp to a beautiful summer get-away right at home.
however, while using the vacuum for the first time this year, we lose prime in the pump. i don't see any air leaks in the hose, and suction is great. we have a new vacuum head and the opening steps down to a smaller connection than our previous head...is this restricting water flow? can this cause me to lose prime?
