Ballast setup, what did I do wrong?
 

I followed this guys setup http://www.wakeworld.com/forum/showthread.php?t=777819 but the ony thing I did differently was cut off my scoops on my factory through-hulls. I tested it out this weenend and I had some self filling issues with my setup. I kept the fill hose as high as possible before entering the bag, other than that, I dont see how I can change anything to not have it flow past and force its way in when I dont want it to.

Any ideas what I need to do?

Didn't he have a shut-off valve between the intake and pumps. You should be able to close that. Might be a PIA but I think he put that extention on the valve to open and close frome the locker.

I didnt see it anywhere in the thread. The whole purpose of my ballast redo was to get rid of those space robbing tanks and the old school cable valves. I thought I was on the right track but I seem to be off a little bit. If I absolutely have to, I will re-install the valves, but I really hate to do that.

for ski locker had to take the thru hull to my buddies machine shop and have it trimmed down to get clearance for pumps

Pick up some of these so you dont have to worry about the valves anymore. They wire in to your pumps. When you turn your pump on they open. When you turn it off it closes. Easy install.

That Ebay valve is a diaphragm valve. Might as well use sprinkler valves and save $$, if you want to go that route. Same thing.

Don, I think your issue is what we talked about yesterday. Since you have no "breather" line t'd off of your fill line, you're creating a siphoning effect. Just add a "T" at the top of the loop and run that line out the side of the boat. If it's the same thru hull as your drain line, add a check valve on the vent line.

Make it easy on yourself and add the "Vented Loop Anti-siphon Valve" to the fill lines. This will alleviate the problem you are having. It is what Malibu uses on their OEM aerator ballast systems.

I installed almost the identical system as well and didn't have any unwanted flow problems. Are you saying it is filling up while underway? Or that once it starts a siphon it just continues to run?

I didn't need the vented loops, but that sounds like it would solve the siphon affect, but not if they are filling while you are moving (the scoop problem).

I know for sure it is filling while underway. I know the bags are bone dry before they fill a little. I know this because it was part of my testing procedure on my new setup.

I did break down and call wakemakers and get the vented loop. I will go half the summer trying to find a cheap way to aleviate this and throwing parts at it or do it right. I called and talked to Jason and he spent a good 40 minutes on the phone with him. I decided to get the 3/4 loop and 3/4 hose and change over from my 1" discarge and 3/4" inlet from the pumps just for flexibility and easier to hide and bend. That was a lot cheaper than doing the 1" vented loops as well and the pumps I am using have enopugh flow for a 3/4 by a long shot (atwood 750/800s). I figured I would just make it easy and do my best to make it look factory. I tested my sprinkler valve in a bucket and it seemed to flow pretty decent, but it required water pressure to reference, which I dont have now because of my cut scoops. If I had not dont that, I would probebly just have used them and called it a day. I know a lot of people are redoing their system that has those, but I figured it does what I wanted and didnt require cable actuated valves. That was all I was really after, but I think I will be happy doing it right this time.
