Hi all,
I'm designing the plumbing for a vet. clinic addition. The current well has a 3/4 HP, 10 gpm pump. The pressure tank is a Well-Ex-Troll 250. The pipe size from the well to the pressure tank is 1".
After counting the fixture units and gpm for the new and existing building, I'm at 44 gpm for the total flow. In my oppinion based on the number of employees, the worst case scenerio would be 20 to 25 gpm being used at once. I actually have two questions...
1) When sizing this well pump, would I size it for total flow? What I mean is, would I need a 44 gpm pump?
2) How concerned should I be with the 1" line coming from the well? Per the WI code, water velocity needs to be 8 FPS or less within the building. I've been told by plumbers that this doesn't apply to the pipe coming from the well. Also, what is the largest pump you would comfortably suggest using with that 1" line?
Thanks in advance for your suggestions!
Shane
