Hi everyone, I'm in IT so I'm having problems getting my head around water pressure.
My pump is 1/2 HP 10 GPM Franklin at 80 feet (water is at 50). So if I look at what Franklin pumps can deliver (curve/table), it shows me that such a pump can only provide 7 gpm at 60 psi and it can only deliver 10 gpm at 40 psi.
So if my use is under 7 gpm, i should have 60 PSI once the pump kicks in - is that right? (or less, because it also has to refill the tank?) Minus the restrictions/friction along the way.
If I use 10 gpm, I can only expect 40 psi?
Does it follow that if I move to a 1 hp pump, my pressure really should never drop below 60 psi as long as I'm using less than the capacity of the pump? (once it kicks in)
I've been told that 1/2 hp is too small for my house (and the calcs I've done really confirm that), but all a larger pump seems to do is provide higher pressure.
So if I want more pressure, I should just bump the HP of my pump... right?
Am I thinking on the right lines here?
