1 1/8” Barbed In-Line Check Valve(W755):

The W755 check valve should be used in all after-market automated ballast systems. Adding a check valve to a system with a reversible pump ensures sacs drain completely by allowing the pump to get strong suction.  A check valve is a critical component when it comes to combatting siphoning. 

Both sides of the valve have 1 1/8” diameter barbs.
