well I run my off a sump pump which is connected to a standard hose
fitting, it took me a little looking at the hardware store to find a
3/4 to 1/2" push adapter. The pump is a 1/4 hp eletrict, it has a
little power getting pressure to the top of my shelve ( a 6' rise)

What you might want to do is see if you can get a larger pressure tank
for your well head.
I am trying to see if I can hook a presure tank into my system if I
expand it and have it make up the pressure difference, I think if I use
PVC and run it to a elevated pressure vessel that I should get good
pressure, the part I couldn't figure out is how to wire, you have to
delay the misters until pressure has built up.
