It depends on how far away the flow test was taken, whether it is looped or gridded, and what the elevation changes are. All of that needs to be considered and isn't by just calculating to the "point of connection".

Like yourself that was what I was taught. If the underground is looped and several flow tests have been done on the loop, the tie in point should be fine too. Regards, G. Tim Stone G.

News to me, any of you guys do it that way? If so how do you account for the loss in the underground to the test hydrant, elevation, etc.... ? Brian Harris, CET BVS Systems Inc.
