View Full Version : Check Valves?????

10-16-2008, 06:53 AM
I am upgrading my ballast system on the X-star.
I am using jabsco reversible pumps to draw the water, and drain thru the same hole.
The overflow is going out a thru hull in the side.
The check valves I am using are 3/4" plastic ones from Home Depot.
The sacs get scary full before any flow comes out the overfil.
Do any of you know what checkvalves are used from the factory( what size, what pressure )
I would like for some flow to happen before the sacs get close to bursting.

Not sure what size the boat came with in a 1999 Star... I would have to say it would be a 3/4" check valve. I know in the X-1 they use a 1-1/2" Check valve with a 150 PSI rating and a 75PSI back pressure ! MC's Part # 300988

Hope that help's
