Tech Support When we receive calls about our hand pumps, typically they fall into one of two categories; 1) inaccurate measuring resulting in incorrect product selection or installation issues. Shallow Well Questions I am not getting any water. Recheck static water level. Be sure it does not exceed the 25 vertical lift from the top of the water to the base of the pump. Be sure all suction line fittings are tight and secure (leak-free). If you continue to have problems, call Bison Tech Support (800-339-2601). I am getting water but then it stops. You have drawn the water down beyond the 25 maximum suction level. Handle wont go all the way down (or it feels spongy). You may have an air lock in the suction line. Be sure that you have removed the brass hose bibb cap on the spout. Be sure there are no obstructions or blockages in the suction line.
