I have a 24+30inch high tank(Stand and tank ground up). This is how much the line has to pull and push. Well not really the line was split in half and put on each side of the tank... the lines are straight but im not getting enuff flow... it really weak, An my valves are open. So what can i do it help this problem? the two lines are 4 feet from each other. Thanks sorry for DP but i was getting no hits.
