Ballast Check Valves

[Matt Garcia]

Ok thanks for the help guys. I will try it out once the weather clears up.

I tried to say that in two sentences but also did not use a pretty picture like you did.

Your two sentence limit is killing your street cred......

ok, on my boat my rear sack always drains too. I have the fill line coming in from the manifold, then the suction line going to a pump, that goes to the hull to empty. There is a t I have in that comes from the top of the bag and goes to exit as well to tell when it's full. I also have a check valve in mine, but I think it is in the wrong place. Is the check supposed to go where? I mean you want it to stop the flow. Will water flow out of the pump? Since I just have all my hoses laying on the floor, and I do know water triies to reach the lowest level, what's the best approach here to keep my rear sac from emptying?

here is what it looks like.

Needs to be on the fill hose.

but I know the water is coming out of the side of the boat. I have watched it. Should I install a check valve on the fill, as well as someplace else?

If water is coming out of your empty line, you could not put a check valve as that would stop the sack from emptying. You will need to install a ballcock.

Would it help if I elevated the pump above the bags?

[mtnsmith]

No. It is probably going out of the vent/overflow line. The check valve you have there is keeping water from going back into the sac when you are pumping the bag empty. I would think elevating both the vent line and empty line would maybe help, but then you run the risk of the water dumping back out of the fill line. A check valve in the fill line would alleviate that problem.

[Domsz06]

ok, that's what I'll do. When I work on it, I'll move some things around. Wonder if I can find another check valve at lowes.

I like this one that is made by Whale. You could probably find it cheaper, but this is the first place that popped up when I searched for it.

thanks. I'll look and see what I can find

Side note where is everyone getting their sacs at? I need to get one or two smaller one's, ie the 250 size, and I thought you used to be able to get them for under 50 bucks, but haven't found them yet. Anyone suggest anything? Ebay doesn't have anythign this small

[mtnsmith]

Well, I have not seen anything that inexpensive but this guy that sells some factory seconds from time to time has some less expensive sacs. Lucky275 sent me the link. I am thinking of getting rid of my hard tanks and was thinking of getting sacs from him.
