Pump Priming and Air Bleed Valve
An air bleed valve is included with each pump to aid in system
priming. It is shipped in the pump accessories bag and must
be installed during system installation.
Why use an air bleed valve:
Most fertilizer systems are equipped with a 4 lb or 10 lb check valve on the end of each hose delivering
fertilizer to the ground. These valves do not let air escape from the system, unless it is pressurized.
PumpRight liquid pumps are not good air compressors. Therefore, the pump can struggle to prime due to air
trapped on the outlet side of the pump.
The air bleed valve is a small
1/4”
valve that when opened lets air escape from the pump outlet at zero
pressure. Open until liquid comes out and then close the valve.
Be sure the air bleed valve tube does not become plugged with dirt or it will not allow air to bleed.
How to install the air bleed valve:
Remove the
1/4”
plug from the quick connect fitting on the pump outlet side (see pictures below). Next, insert
the
1/4”
tubing in the quick connect fitting. Run the
1/4”
tubing to an easily accessible spot on your
equipment. Next, cut the tubing and push the
1/4”
valve onto the tubing. Finally, run the tubing to a low
location where any fertilizer that escapes will run on the ground.
Be sure the air bleed valve tube does not become plugged with dirt or it will not allow air to bleed.
