Unloader Issue!

This is my first trailer mounted setup.
Honda GX 340 11hp motor with a General 4040G pump 3000 psi @4gpm.

The unloder bypass line ran from the bypass port back to the inlet of the pump. I deceided I would run a new line from the bypass port to my water tank. This would ensure that fresh water would be entering the pump at all times. After hooking everything up I fired up the pump and pulled the spray gun everything was operating correctly. When I released the spray gun handle water was flowing back into the tank through the new bypass line. My next test was to check the flow with the gun handle depressed. Water was still flowing from the bypass port. The flow was not as strong but still coming from the bypass port while spraying.

Any suggestions??

It sounds like it is doing exactly what it is supposed to be doing. When the gun is open, you should still get 5%-10% flow to the tank (from the bypass)

Thanks for the reply!

your welcome!

We've went through a handful in the last few days.
