Over the years I have written about many aspects of water well drilling and water systems. Some of these are drill rigs, pipe for well casing, pipe for drop pipe, pumps, well screens and other subjects. All of what I have written has been what I have experienced in a career of over 70 years if you include my years with my dad as his companion before I was old enough to be much of a helper. This article starts a subject on a component that is a very necessary part of almost any domestic or commercial water system, a pressure tank — sometimes referred to as a holding tank.
Now, for sure, there are some uses of pumped water that do not need a pressurized system: direct connection to an irrigation system and filling ponds, farm tanks, fruit cooling tanks and some others come to mind. I’m sure some of you readers know of uses where just water and not water under pressure is all that is needed. Just about every domestic system and most commercial systems, especially the small ones, do need water under pressure. For the system to operate properly, a pressure tank must be a part of that system.
