    There are a few threads that address this issue. The best way to fix "the buck" is to understand it. Basically, it occurs when you are overstuffing the pump -- i.e. you are moving at a rate that more water is attempting to pass through the pump than can actually pass through the pump. You get a situation where there is positive pressure in front of the pump. That is not a good thing.

    Are you using a pump with a two inch spacer (HO pump)? If so, you can drill into the spacer and place fittings into the holes that you drilled. Put lines on the fittings and valves on the lines. When you generate positive pressure in front of the impeller (e.g. in the zone of the 2" extension), the valves will open and relieve that pressure.

    If you are going the speeds that some of these maniacs are hitting you may need more than the two valves running into 3/8" lines that I am using.

    Do a search for "buck" or "overstuffing" and you will find a lot of good information on the subject.

    I did not do any of this research or any of the leg work. I am just parroting back what I have read and what worked for my ski.
