Well I am getting ready (for the last few months) to put in two rear bags and because of having an OBV and do not want to drill a new thru hall for the intake I will have to use sprinkler valve's.

So does the size really matter? The sprinkler valve's come in 3/4" and 1". I am replacing the thru hall intake with a 1" intake and installing two pumps. One is a 1200 GPH and one is a 800GPH. Should I install 3 1" sprinkler valve's with 1" hose to each bags or will it matter if I just use 3/4" sprinkler valve's wih 3/4" hose to each bag? Another option would be a 1" valve and a 3/4" hose.

This is an image of the two pump setup outside the boat for testing.

From what I remember there wasn't that much of a difference between 3/4 to 1

Jester,
Adding the additional pump should help some, but the flow will only go as fast as the smallest diameter opening.
