All I've ever been able to get is mfgrs. recommendations Todd, no clear code direction. It became an issue with a 4" inlet m/s pump fed by an 8" supply one time, more directly on the clean supply line and what size. They stepped down to 6" and ran the appropriate diameters length to the main os&y, tee, suction os&y and reducer, to 4". I can see an issue with turbulence bolting multiple reducers on the suction side but not sure about discharge. I'm sure there's a single reducer available. At that time, the factory rep suggested maintaining 10 diameters between steps of more than one pipe size on supply which is what they did (except for the 6x4 bolted to the suction flange). Hope this helps. They didn't order it from a warehouse did they? Tom
Be careful on the suction side---- eccentric, top flat Any issues with having multiple reducers on the suction or discharge on a pump? It is what the supplier sent. Todd G.
