Fresh Water Tanks

[Atomic77]

While looking at fresh water tanks, I'm noticing they are listed as "pressurized" and "non-pressurized" tanks. Besides the obvious, one is pressurized and one isn't, what are the differences in application? Thanks!

The pressurized tank will have the water pumped into it under pressure with a rubber diaphragm separating the water and air at the high point and the whole system will be pressurized, it will also have domed ends.... think of a pump and well system for a house.
The non pressurized will simply be a holding tank, square, rectangle, etc. that will only have to deal with inches of water column pressure (about a half a pound per 12 inches, think 5 gallon bucket) with a feed tube off the bottom to either a spigot/valve for gravity flow, or a pump to pressurize the line only to your valved outlet. Simply a reservoir Just my 2 cents worth.

This guy has lots of non-pressurized (gravity or pump flow) water storage tanks for reasonable prices.
