  • Bison Pumps, Frequently Asked Questions

Who knew hand pumps could be so complicated?! Here, we address some questions we get frequently. As always, you can speak with a knowledgeable sales representative by calling 1-800-339-2601.

Why can’t I use the Inline Pump System?

The Inline Pump is only for special well setups. Unless the casing is small (less than 6 inch diameter), the pumps can be installed side-by-side and function independent of each other.

Can I pump directly into my 200 gallon pressure tank?

YES! All Bison Pumps are pressure pumps, which means they are a closed system and can be used to pressurize a tank. Bison Pumps sells check valves and pressurizing kits for this purpose.

Can this pump handle freezing weather? Will I have to uninstall the pump during cold weather?

With the Deep Well model, you can prevent freezing and use outdoors year round. Prior to installing the last piece of pipe and rod, drill an 1/8″ weep hole in the pipe just below where the frost line is for your area. This will allow the water to seep back to that point, yet maintain the prime due to the check valve in the cylinder. Please note, you cannot do this with the Inline Pump.

Do I have to drill a hole in my well cap? If so, what size does the hole have to be? Where should the hole be in relation to the bump on the Well cap?

The well adapter on the Bison Pump head will replace the existing well cap. There is an opening for your wires to exit the top of the casing. We also offer Conduit Els to carry your wiring to your existing electrical connection if you need that. If the pipes from your electric pump exit the top of your casing, we have a well adapter for that configuration too.

 

What’s included in the total price?

 

Bison Pumps are designed for a lifetime of use and therefore come with a lifetime warranty against manufacturer’s defects. They are constructed from high quality stainless steel including the lift rods. The pump head is a one piece design and all the parts are welded and hand polished. Bison Pumps are self-priming and don’t require any routine maintenance. And your quote covers everything needed to install your Bison Pump, including safety rope, installation paddle (to hold PVC) and rod retrieval tool.

Why is Static water level required just to provide a quote?

If your static water level is quite deep, we suggest checking that measurement, as it affects the size of cylinder we recommend as well as the amount of pipe that is needed.

The best way to check your static water level is to simply drop a weighted string into the well casing until you see or hear it splash the surface of the water. You could also use a weighted string with a float, so that you can feel the line go slack. Mark the string where it lays on top of the well casing. Then measure that distance.

While you have the cover off, measure the inside and outside diameter of the well casing. If you have a submersible pump, you should also check to see what will slide past the pitless adapter. You can do this with a length of 3”, 2”, 2 ½” or 1 ½” PVC pipe. This will help us determine the largest cylinder size possible for your application.

If any of these measurements are different than we thought, we can make adjustments to your quote.
