Best 2 gallon well tank?

[JoshB-NC]

This is for the pump house that runs my irrigation.

Original 2 gallon tank lasted 5ish years then rusted through. It was an Amtrol I think? Grey in color if I remember correctly. Well guy had installed it.

I replaced that with a 'water works' from home depot... apparently garbage as it lasted less than 2 years, rusted through in a big way.

I searched for a 2 gallon stainless - but cannot find anything. Very limited on space. Worst part is this well house is on corner on property and from looking inside it I would guess this has been leaking for a long time...

Any advice would be great....!!

I have a sprinkler system that runs without a tank. I pull water from my well with a sprinkler pump and the pump sends it directly to the sprinkler heads. Not sure what your set up is like. Maybe it won’t work for you. Just telling you what I do.

Thanks for the reply, but pretty sure I need it. It is a variable pressure pump - also feeds my geothermal system.

There are ways to run both the irrigation and heat pump without a tank. But a tank will probably make it easier to run multiple things in different locations. It is rare for a tank to rust through from the outside, even in salt air environments. Flexcon makes both a Stainless steel and a fiberglass tanks if needed. However, most tanks rust from the inside out after the bladder is broken. The air chamber in the tank is not coated for water, so when the diaphragm breaks the upper chamber rust out quickly. You should have noticed some rapid cycling or high pressure with the waterlogged tank? If that is the case it is most likely the variable speed controller that is destroying the tank diaphragms. When the variable speed controller goes haywire it can cause the pressure to spike like in the video posted below.
