Many of our customers intend to use their Bison Hand Pump when pressurizing water tanks. If this is an option you would like to consider, Bison now offers a check valve (P/N BPN-330C). This check valve will screw to the outlet of your Bison hand pump and will prevent back pressure onto your hand pump while pressurizing a storage tank and make pumping easier. This check valve only needs to be used when pressurizing a storage tank.
Please do not try to pressurize your water tank without the use of a check valve as this causes back pressure within your Bison Pump and may cause internal damage.
The standard setup for using a Bison check valve would be to attach the check valve to the outlet of your Bison Hand Pump and then attach a regular garden hose to the check valve. Attach the garden hose to your water tank.
