Was wondering if anyone was able to use bronze ball Y valve 1-1/2 typically used for plumbing but in a waste system on a boat. The cost is the same for about $65 you can get either Jabsco Y valve or you can get an all bronze Apollo (Apollo 70-600 Series Bronze Ball Valve, Two Piece, 3-Port Diverting, Lever, 1-1/2" NPT Female: Bathtub And Shower Diverter Valves: Amazon.com: Industrial & [email protected]@[email protected]@http://ecx.images-amazon.com/images/I/[email protected]@[email protected]@51KZnqlfMTL)

Thanks

the Y valve is full port and most three way bronze valves are reduced size ports which could cause a restriction. the Y valve is the same as 45 degree elbow when it comes to flow restriction. the diverter valve is the same as a 90 degree elbow which is more the twice the flow restriction of a 45 elbow. two 45 elbows is less restriction the one 90 elbow when it comes to flow.

the Jabsco valve is lockable which is required by the CG if it goes to a thru hull

if you have a through hull seacock that is lockable then the diverter is not bad but i think you may want to size up to ease any flow restriction
