Issues with project waterpump

[jayhardy]

I have a 2014 Montana that came with a project Waterpump. I can't get it to work. I filled the water tank, turned on all the faucets, and then turned on the pump. I can hear it but no water flowing after 5~7 minutes. Any thoughts and where I'm doing wrong.

Close ALL the faucets


Then with pump ON open the hot side of closest faucet until water flows.
This allows pump to prime.....fill water heater tank and pump thru hot lines.

Then you can purge air from cold side and then go to other faucets/shower/toilet etc. one at a time

If you have an antifreeze siphon line check to make sure the valve isn't open to the siphon side.
