Ballast Help!
2 problems and potential solutions.
1. My ballast is self-filling. I have to manually shut the valve if I don't want my ballast completely full after motoring across the lake. I'm picking up some Irritrol valves tomorrow as I understand these eliminate the passive fill problem. Additionally I can't get my bags to consistently fill without driving around to force water in. I recently replaced the pump but the whole system is still not as dependable as I'd like. I had grand plans to do individual pumps/thru-hulls similar to what Berg and others have done, but do to limited bilge space and a poorly placed paddle-wheel, it is just not feasible for me. Is there anything else I can do to speed up and improve the function of this system.
2. I replaced my locker bags with 750s. Due to the poor function of my ballast system, I've never been able to fill them all the way. This weekend, I got them both a little over half full and they started emptying through the drain pumps. Could this be due to worn drain pumps (they are original to 2002)? Or is there something else I need to look for? I plan on replacing them anyway as I already had ordered 2 Tsunami 800s that I no longer have a use for. I am also adding vent lines as the original system didn't have them.02 Mobius LSV

Don't know. I just searched for your thread and didn't even look for the pics.
Don't know what happened, but stinks that we seem to have lost them.
Do you remember if they were links to an online album or attached from your PC?

Or enlarging your existing thru hull, then doing a small manifold off that to your pumps. I've seen some pretty creative setups on other brands of boats on WW made out of PVC. Also noticed on the new Supreme boat at the PDX boat show that the fill ballast pump inlets were going out the transom but that boat is pretty deep and lots of transom to work with.
The cheap/effective route until you have a solution on the self-draining is a couple wine corks stuffed in the exit thru hulls. I used to do that and it works great as long as you don't forget 'em.
On the self filling - do you have a scooper style thru hull? I have heard that can be the culprit and to either cut out the scoops, or replace with a mushroom style.So when is this "old enough to know better" supposed to kick in?

How do the aerator pumps work without the scupper through hull? I thought you needed this to prime the system??

If the pump is below the water line and the outlet is oriented in a manor that it will allow air to purge out, then the pump will prime when the boat is launched. If the pump is too high in the bilge or the draft of the boat is too shallow, or the pump is not turned so the outlet is up, air will be trapped, thus preventing priming.
