Corbin, You can quote any engineer you would like! Ive been working around them for 30 years on all areas of fluid transfer field… and Ive been correcting their prints & P&IDs all along too. I especially enjoy the ones who say Pipe it up and Ill come out to check it, what they really meant is theyll draw it up after youve installed it! At least thay dont waste my time having to run back to them through out a project seeking approvals for corrections.I stand by my original statements, and Ill remind you of yours, quote…. Imagine having a 1-3/4inch pipe flowing full speed ahead to your house from your well. Then imagine all that water trying to fit into the 1/4inch pipe inside your house. The force behind the water must go somewhere; that somewhere is your piping network. This will cause unwanted stress on your pipe joints. end of quote…..Maybe you would like to re-think or re-state this statement. But you should understand that the amount of water which will be flowing full speed ahead thru the 1 3/4 pipe will be the same quantity as is flowing thru the � line only at a much slower rate. In fact this full speed ahead you speak of will probably be slower than all ahead 1/3.You see, pressure in a piping is exerted equally in all directions (except for the velocity of the mass when it is in motion. It is only in motion when it is seeking the point of least resistance (i.e. an opening in the piping system) That � pipe can only accept a limited amount of water provided by larger pipe at a given pump pressure, (not taking in to account the velocity because there is none to speak of, in the larger pipe considering the vastly different pipe sizes.: Corbin, : I think you have cleared up much of the apparent disagreement. : We in the US want to be able to use multiple fixtures at the same time without noticable pressure loss. And we are wasteful…But that is slowly changing. I wouldnt be surprise if some day we move in the direction that you have been describing to us. : Thanks for giving your time to help others. : This internet sure makes the world smaller. : Don
