Step #7: Pump water
The installation is complete. Begin pumping the Bison Model 1900 Stainless Steel Pitcher Pump until
water begins to flow. It is not necessary to prime the pump.
Installing on a Driven Well Point with a 2” NPT
Step #1: Determine the material type of the casing
Steel: If the casing is steel, then the Bison Model 1900 Stainless Steel Pitcher Pump can be installed
without any further additions (Detail F – Item A).
PVC: If the casing is PVC, then Bison Pumps recommends that some type of support structure (Detail F –
Item B) be built on which the pump will be installed (like a countertop installation). The PVC pipe may
not be rigid enough to support the pumping action and could result in damage to the PVC pipe.
Step #2: Connect the water pipe casing to the pump
The Bison Model 1900 Stainless Steel Pitcher Pump can accept 2” NPT pipe. Apply Teflon tape to the
threads of the 2” NPT pipe casing. Carefully place the pump over the pipe casing and begin threading it
onto the pipe casing. Be very careful not to overtighten onto the casing. Turn the pump until it is hand
tight. Adjust the spout orientation to your requirements without overtightening.
For installations using a support structure, follow the instructions for countertop installations.
Note 1: To drain the pump and water pipe, there must be a free flow of water back to the source.
Therefore, it is important NOT to install a check valve or foot valve in the water pipe at any point
between the pump and the water source.
Step #3: Adjust the handle orientation
The Bison Model 1900 Stainless Steel Pitcher The pump will come with the handle in either the 3, 6, or 9
o’clock position (assuming the spout is at 12 o’clock). To adjust the position of the handle, remove the
four top screws (Detail E – Items A) in the Top Plate using a 5/32” Allen wrench. Rotate the handle to
either a 3, 6, or 9 o’clock position as desired. Once the proper position is found, replace the four top
screws into the Top Plate. Be sure to re-tighten the screws by partially tightening the first one. Then
proceed in a pattern going diagonally across to the next one until all four are partially tightened. Repeat
the process and completely tighten each screw.
Step #4: Pump water
The installation is complete. Begin pumping the Bison Model 1900 Stainless Steel Pitcher Pump until
water begins to flow. It is not necessary to prime the pump.
