IT WAS REFERENCED IN THE PREVIOUS THREAD, IF U CAN'T OBTAIN FIRE FLOW, THEY INSTALLED A DRY HYDRANT WITH AN UNDERGROUND STORAGE TANK. I'M THINKING THIS WOULD BE A PRACTICAL WAY TO GO. CAN ANYONE POINT ME IN THAT DIRECTION FOR INFORMATION ON THE MINIMUM SIZE OF THIS TANK, CAD...
Readings at two local fire hydrants on a 4" line, so we are a ways from the reservior, but what else might cause the vast difference in static vs residual psi at the main line.
Static 190 psi
Residual 20 psi
Flow rate 100gpn
Re-ran the test and got the same results. I need to serve 6 homes...
