I have a Ninja 500psi only 5 months old. I run it at 350 psi using my rotovac rotary. Its fine, however when using the Bonzer and cranking up to 500psi, after an hour or so, I lose pressure to the point it just comes out in short bursts. then nothing at all. after it sits for 10 minutes or so its fine. any suggestions where to start looking to solutions? I dont think the jets are blocked because starting out its great until after an hour or so,. this has happened several times. looking for possible reasons to check. thanks

Possibilities:

1. Chinese QD"S or using two different manufactured QD's.

2. Restriction on inlet side of pump (ex: kinked hose)

3. PSI pump Drive motor not large enough

Most likely, one of those above.

Hope this helps.

The jets on the bonzer exceed the flow capacity of your pump. 1) Remove some of the jets if you can. 2) call the pump company and ask them if the have a higher flow cam. ( this will likely reduce the psi capability of the pump) 3) change your jets to smaller orifices and lower your flow.
