I had the same issue. I e-mailed the guys at Wake Makers and here is their reply:
The issue you're encountering is a result of underlying flaws in the factory system in your boat. The quick fix is to replace the broken sprinkler valves that are currently in the boat, which will stop the auto-filling option, until they break again. The more complete solution is to overhaul the factory system to completely eliminate the sprinkler valves.
We can help you with the latter, for the former, you'll need three Orbit irrigation valves, which you can get at Home Depot or Lowes.

I bought the Orbit Valves at Lowes and it works great now. They are only about $12.00 each so it is a pretty easy and cheap fix.
good luck
Replacing the valves is the thing to do, you can also go into the moomba forum and you will find lots of help in the how to forum or doing a "sprinkler" search
