can you have too many well water pressure tanks?

I have three 119gal pressure tanks installed on my well system. I'm thinking about adding another one or two to the same system (my well waters big fields). Is there any harm in doing this?

No problem adding another pressure tank.

Suggest having a shutoff valve at the neck of each tank, and be sure that at least one tank has the shutoff valve open before restarting the pump.

Be sure to preset each tank as if it were the only tank in the system, namely to preset it to well pump turn on pressure minus 2 PSI.

The purpose of the shutoff valves is to be able to depressurize the system for maintenance or to install or repressurize a pressure tank without wasting the water that has entered the other pressure tanks.

yes, each tank has it's own shut-off valve. Thanks for your quick response!

Although I agree it's not going to hurt anything a better solution would be to get your output to match your pump capacity so that regardless of the number of tanks they technically would not be needed!

The only other issue I can think of is the possibility of running your well dry, temporarily, while the pump, pumps that much water up and then does nothing for long periods of time. Good for the pump. Bad for the well. The well would prefer you to pump smaller amounts more frequently.

OptsyEagle - that's a great point and makes sense, thank you.

A pressure tank's primary purpose is to moderate how often the pump turns on and off. It's not really intended for large volume storage. I would look at what people do that have low producing wells. They often have smaller pump that brings the water up to a tank. This low volume pump draws water at a rate that the well can supply without running dry so it can be run for long periods. The accumulator/storage tank can be any size you want. Then a separate pump & pressure tank generates the pressure and supplies the water as needed.
