I cant remember, I did get on Lowes home improvments website and found some ball check valves for 6 dollars. They take 2 psi to open so I'm gonna pick them up today. I figure my pumps should be able to produce 2 psi of pressure. I know this ballest has been an on going PITA, seems like everytime I take the boat out I find an improvment I can make to the system, it works great but not perfect.
