I could never figure out what was wrong with the original model so I just built a new one with the pump definition listed above and it works! Thanks for all of your help!

CPENG78: I setup a new temporary model using a reservoir, pump and a junction in an effort to simulate just the FH fire flow test with these values for the pump: 196.35 ft w/ 0 gpm 138.6 ft w/ 1062 gpm 46.2 ft w/ 1779 gpm At first I was getting negative pump flows, then I changed the...

I ran the model using just a reservoir (I wasn't sure how to set it up using a pump). For the head calculation, I took the ground el. (132) + 85 static pressure (196 ft) = 328 ft. I placed a temporary node right next to the reservoir and ran the model to verify the static pressure. It looked ok...

I located the .mdb file and also included a .dhw file. There were also multiple .out files but I'm assuming those are the results from the model. I keep getting errors when attempting to upload the files above to this site, so I've posted them here...

The residual from the fire flow test flowing 1062 gpm is 60 psi.

I've gone thru and setup the reservoir as you indicated and eliminated the other reservoirs so that I have one source. I ran the fireflow analysis and the results indicate that I have 8,718 gpm at the first junction near the reservoir (which I know should be around 1,800 gpm @ 20 psi). All other...

Thank you for the thorough response. I will try what you suggested above and will post a subsequent reply of the outcome....stay tuned.

I have very limited knowledge on Water distribution (drainage is my forte). I have an existing 10" main to the south and a 6" main to the north that I'm required to tie into by the city. I have 2 hydrant tests, 2 along the 10" main on the south with these results: FH1: Static=85; Pitot=34...
