@cruisekingkris My pump turns on at 40psi and cuts out at 60psi. That's 2.6 bar and 4 bar for the metric peeps. As
@tbone1004 pointed out, it acts as storage tank, so I can take long hot showers, but it also is a buffer, so that I don't feel the start and stop of the pump during normal usage. This one is OLD and when it's full, 4/5s of it is water and the top 1/5 is air. Today, they usually go a lot smaller with a bladder between the air and water. My well water is simply awesome with high amounts of Calcium carbonate and a tiny bit of fizz. It's more of a mineral water, than actual spring water. While the water table in this area is about 15 to 30 feet, the truly sweet water is deeper than that. Supposedly, my well goes down 80 feet. When the Suwannee river floods, houses about 3 miles closer to the river than me have to use bottled water due to river water intrusion. I'm good year round because of that depth. BTW, when you first pour a glass of water at my house, it looks a bit dingy. Then you notice it clears from the bottom up. What you're seeing is that bit of fizz I referred to earlier.
Recently Nestle petitioned Gilchrist Country to pump more water out of our aquifers. The county denied the permit and I'm quite happy with that. There's a lot of pressure on our aquifer system already and we're seeing some springs and shallow wells dry up as well as salt water intrusion further inland. In addition, the one use plastics used in this kind of bottling plant are killing our environment.
I have done a lot to my property to improve the looks. The south end looks more like a park nowadays than just a bunch of brush. Straightening the tank as well as upgrading the enclosure will go a long way to making it even nicer!
