How to Prime a Jet Pump

How to Prime a Jet Pump
The pump housing and the pipe(s) leading to the source of water must be filled with water before pumping begins. A jet pump uses water to pull additional water out of the well. Always remember to NEVER RUN A JET PUMP DRY.

Step One – Make tight connections
All inlet pipes must be air tight to prevent loss of prime. Teflon tape or drinking-water-safe pipe thread compound can be used effectively.

Step Two – Completely fill pump and pipe(s) with water
Fill the system slowly with fresh, clean water and permit all air to escape. Replace the priming plug firmly.

Step Three – Test for prime
Turn on power to the pump. If the pump does not produce water within five minutes, shut off power to the pump and re-prime.
You may have to repeat steps two and three several times to remove all air from the suction pipe. If you don’t get rid of all the air in the pump and suction pipe, the PUMP WILL NOT PRIME.
NEVER RUN THE PUMP DRY. Doing so will void the pump warranty.
