Exactly WHAT PART of the system ACTUALLY determines the pressure?
My well was working pretty good (pressure wise) until the plumber came to replace some of the parts on my pump that went bad. He said the pressure in my pressure tank was TOO HIGH, my switch was a 20/40, and my pressure tank should be charged to 18psi always 2psi before cut in pressure.
Now when I take showers in the morning, I can DEFINITELY tell when the pump is about to come on, because the pressure will be pretty low for about 5 minutes prior. Its enough water to shower with really, but its low enough that it takes a lot longer to rinse your hair out, which is pretty bad considering that I cut my hair to 1/8".
Anyway, here's the way I THINK it works..... pump (jet pump) pulls water from the well, and fills the pressure tank up until the pressure in the tank is 40psi. Once the tank gets down to 18, the pump will kick back on and repressurize/fill the pressure tank.
What i'm confused on is what is actually determining the water pressure. It seems that adding a more powerful pump will only reduce the time it takes to fill the pressure tank. Since the plumber said always 2psi below cut in pressure, I'm thinking that a new pressure switch would allow me to put more air pressure in the pressure tank?
I've even lost myself now. Gah.......
