There are O rings and I've tightened the collars on the hose where its been leaking and tried various things with different levels of success. But still no way to stop it from leaking. I went from only 1 joint leaking to 3 now. I was ready to break out the silicon and teflon tape next. ;-)

Anyways I called Polaris and after pressing the numbers on the phone 42 (the answer to life, the universe, and everything) times, I got through to a Polaris tech person who pretty much said it was a noob question and that the Polaris 360 hose should leak at the joints. As long as the wheels are turning at the correct revolutions everything should be fine. I told him one joint more than dribbled and he said I may have too much pressure. That might be true as the pressure relief valve is releasing some water.

And here I was worried I may not have a big enough pump to drive it.
