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

  1. I am not getting any water.
    1. 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.
    2. Be sure all suction line fittings are tight and secure (leak-free).
    3. If you continue to have problems, call Bison Tech Support (800-339-2601).
  2. I am getting water but then it stops.
    1. You have drawn the water down beyond the 25′ maximum suction level.
  3. Handle won’t go all the way down (or it feels spongy).
    1. You may have an air lock in the suction line.
    2. Be sure that you have removed the brass hose bibb cap on the spout.
    3. Be sure there are no obstructions or blockages in the suction line.
    4. If you continue to have problems, call Bison Tech Support (800-339-2601).
  4. Water is leaking around the rod at the top of the pump.
    1. Turn the gland nut clockwise a quarter turn by hand. If this doesn’t stop it, turn a little more until it stops leaking. Do not overtighten. If you do overtighten, it will cause the pump handle to pump very hard.
    2. If you can’t tighten the gland nut enough to eliminate the leak and still pump easily, replace cup seal under the gland nut.
  5. How much water should I be getting?
    1. See our Bison Shallow Well Hand Pump Comparison Chart.
  6. Which line do I tap into when I have a 2-pipe jet pump?
    1. You connect to the suction line which is typically the larger diameter pipe of the two lines. Be sure to connect on the suction side of the jet pump.
  7. Do I need a repair kit? Does this pump require routine maintenance?
    1. No, it does not require routine maintenance. But for convenience, Bison Pumps has a repair kit for wearable parts. See the repair kits in Shallow Well Accessories.
  8. Do I need to prime a shallow well hand pump?
    1. No, because all Bison Pumps are self-priming.
  9. Does it have leathers?
    1. No, we use buna rubber cup seals and non-corrosive parts.
  10. How do I keep this pump from freezing? How do I drain it?
    1. Refer to Bison Shallow Well Hand Pump Comparison Chart.
  11. How do I pressurize a tank?
    1. You can purchase the pressurizing kit which attaches from the outlet of the hand pump to the drain valve of the pressure tank. See the check valves or pressurizing kits in Shallow Well Accessories.
  12. Pump is squeaking when I pump it?
    1. Apply some cooking spray around the gland nut where the lift rod goes into the top of the pump.
  13. How do I add chlorine to my well if I have a hand pump on the well casing?
    1. Bison Pumps have two holes in the well adapter; one has the mushroom vent plug and the other a regular plug for wires to come out the top. If you did not use the hole for the wires, then remove the plug and use that hole. If that hole is in use, carefully remove the mushroom vent plug.

Deep Well Questions

  1. Why is it so hard to pump?
    1. Did you tighten the gland nut at the top of the pump? It should not be overly tight. Untighten slightly, but not enough to let water by it.
    2. Your cylinder may be plugged. Is sand or silt an issue in your area of the country? If so, you may need a silt screen. See all Bison Pumps Deep Well Accessories
    3. If your static water level is very deep, you are lifting approximately 1/2 pound of water for every foot. See our Cylinder Spec Sheet for pumping difficulty at various static water levels.
    4. You may have an air lock in the suction line due to the dropping of your static water level. Wait for the water level to return and try again.
  2. Why is there water coming out the top of the pump?
    1. Turn the gland nut clockwise a quarter turn by hand. If this doesn’t stop it, turn a little more until it stops leaking. Do not overtighten. If you do overtighten, it will cause the pump handle to pump very hard.
    2. If you can’t tighten the gland nut enough to eliminate the leak and still pump easily, replace cup seal.
  3. Do I need a repair kit?
    1. No, it does not require routine maintenance. But for convenience, Bison Pumps has a repair kit for wearable parts. See the repair kits in Deep Well Accessories.
  4. Why is my pump frozen?
    1. Did you remember to drill the 1/8″ drain hole below the frost line of the last piece of pipe and rod installed? If not, you will need to do this.
    2. Rod could freeze at the packing gland/gland nut. Put your warm hand around gland nut to see if it will warm it enough to thaw.
  5. Why am I not getting any (or very little) water?
    1. Static level has dropped. Wait for water level to return.
    2. A drop pipe is cracked and leaking.
    3. Did you purchase the correct cylinder for the depth. See our Cylinder Spec Sheet.
  6. I am not getting the water volume as advertised. Why?
    1. Water volume is measured by pumping the handle from “all the way up” position to the “all the way down” once you have water flowing. Wait until water stops flowing and immediately pump again.
  7. Pump is squeaking when I pump it?
    1. Apply some cooking spray around the gland nut where the lift rod goes into the top of the pump.
