my question is will my pump handle the total head hight that i have.head will be 6.5 feet to 7.5 feet vertical but i have a distance of 30 to 40 feet horiz. in between. i know that distance will restrict my flow this is what iam worried about the pump does good up to 10 feet 1520GPH 12 feet 630GPH anything over that pump shuts off.iam not worried about having that much flow between 1500 & 600 is good for me.iam running 1'' pipe.so does anyone know what my total head hight will be.or do i need a bigger pump. the pump is a reeflo dart.thankyou for your advice.
