Why Does It Always Have to be Done That Way?
Myth 3: The 2-1/2” auxiliary intake should not be used for a large flow operation.
Reality: I agree that it should not be used at least as the primary intake in a large flow operation, however, tests have proven flows up to 800 GPM through a 2-1/2” intake that was supplied from a relay pump operation. If large diameter hose is available, it should be used in conjunction with the 2-1/2” intake and connected by means of an adapter. The 2-1/2” intake is restrictive enough, let’s not restrict it more with small diameter hose. If all you have left is a 2-1/2” intake, use it, you may be surprised.
The performance of the 2-1/2” intake can be improved using LDH
