Water Sorage....Will this Work?

[Jimbrown]

Yep thats true. I misunderstood and thought the storage tank was at the well head. I have my storage tank and pressure tanks at the well head. Sorry for not undrstanding. your way will work just need to be sure the float will reliably shut off the pressure switch. I would get one with the lowest cut off I could find 40Lb I think and then maybe try to set it lower. I have not had much luck changing the cut off on the pressure switches.

Wouldn't another advantage to a large storage tank be to make up for a slow production rate out of the well? and/or expected large bursts of water consumption?

If the well pump is only used to fill a storage tank then it can be a much smaller pump with smaller line and smaller flows. From the storage tank, a jet pump can be used to bump the stored water up to full pressure.

I like the sound of the CSV too. Am I reading that this system eliminates the need for the large blue expansion tanks? What kind of extra cost for that.

I have used PE to drop a temporary pump in my 80 foot well but I often wondered if it would wind up when the pump kicked on and off.

The higher than normal water use will require the well to produce that volume to refill the tank. The pump runs will have to be timed or the well goes dry. Then there is little sense in having the tank. Unless you pay for delivered water for the tank or time the refill over hours; which isn't very difficult to do.

store water to keep the well from going dry!!! now i understand!! i guess i missed that somewhere...i've done that a couple times.. using a timer on the pump, so it would kick on and run for a few minutes, making sure it didn't run long enough to pump the well dry..but it would kick on 24-7..so it kept up with usage: used a solenoid valve from an ice maker once..that actually worked pretty well: the float activated a small switch that would shut off power to the solenoid: cheap and readily available.

So I assume you are using the pressurized line to avoid the problem of wireing the controller the 900' from the tank to the wellhead. If I were doing it this way, I think I would put in the controller at the tank and wire it, skipping the pressurization step and have the float switch in the tank control the pump directly. 2000 gallons is a lot of water for the initial fillup, but once full I would set the floats up to always keep it topped off. Is this tank below ground. You could also have water quality issues with well water exposed to air(from the tank air vent) in the tank for long periods, particularly if it is heated/cooled by sun and ambient air temp. Since the purpose of the 2000 gallons is a backup to a failed well pump, I am assuming you will have another float switch set to sound an alarm if the water drops below the lowest mormal tank level.

If he doesn't use pressure to control the pump, he must control the 230vac to the pump, which would require a more complicted 'fix' and mucho money. Keeping the 900' of water line prressurized is another benefit.

If it were me, I'd do away with the storage tank unless it's required for fire fighting. Stored water suffers quality wise, which then costs more money and maintenance.
