Galvanized well tank questions

[Hobby_Man22]

Over Easter I visited some friends and asked about his well tank. He's claimed he's had it for 25 years and never has had to do anything with it. It has no air bladder or air volume control valve to go bad. So I don't understand how it develops pressure so the pump doesn't short cycle every time you turn the water on. Not sire if it matters, but he has a shallow well pump where you have to pull it out of the ground when it goes bad. Pretty sure he's had to do that atleast once, but he's never had to drain the water out oxcassionally or adjust the pressure of the air bladder to keep an airpad at the top of the tank. My setup is a jet pump where the pump is above ground and right next to the well tank, but mine has an air volume control valve and every 3 months or so I have to drain the water out and refill it so it retains the airpad so the pump doesn't turn on so often. This setup *****. I want to get one of these galvanized units or maybe even two of them side by side so I have a good 160 gallons or so and just have the thing cycle on like once a day and pump like 50 gallons into the tanks for the whole days water usage. Is this possible with two 80 gallon or even 100 gallon tanks? Looks like it's a galvanized hydropneamatic tank whatever that means.

All it has is that pressure guage in the middle and two ports at the bottom of the tank for the inlet and outlet pipes. One pipe plug at the very top also

I don't see anything about drawdown capacity.

Thanks for this. I actually think this is what everyone around me uses.

Looks like the gauge is threaded into a standard air volume control for galvanized tanks. Typically the pressure switch is mounted there as well.

I guess I missed that. His is a submersible pump. This tank is in the garage and the well is like 100ft away out in the yard.

I guess this is what it is. Mine has a tube that goes from the air volume control valve back to the well pump. I wonder if that tube isn't needed on mine? It's already got a pressure switch to turn the pump on and off. Turns on around 30 and off at like 58psi

Robot or human?

When I moved into our house back in 2010 the water tank that was here was the same type of galvanized tank you have shown, with the exact same pressure gauge at the exact same location. And the air volume control was mounted there just like gregs mentioned.

That tank was installed in 1974 (according to the date written on it and the paperwork the previous owner gave us) and it lasted until December of 2020 when I spotted a small leak starting at the fitting that was welded to the tank for the incoming water line from the well.

So I would guess that 46 years of service is pretty good for those types of tanks.

Not sure why I have the only oddball blue painted tank. Mine is from 1999 though. But like I said, it gets water logged very fast and short cycles the pump..

Your tank is shot but dont replace it with anything but a captive air tank they keep the air and water separate with a plain galvanized tank a little air leaks out every time you open a faucet so man has invented numerous different ways to make up for it none of which work as well as a captive air tank.

You mean the galvanized one I'm talking about?

Our tank us 800 gallons and has automatic air control. Air over water (bladderless) is pretty common. It helps a lot with dropping iron out of the water.

I'm sorry when you said you have a blue tank I assumed you had a tank with a bladder in it. In your area is it common to use very large tanks to act as settle tanks because the water has particles in it.

If it has no bladder or air control valve AND no Shrader at the top, his tank is doing nothing.

No we confirmed my friends tank pictured has a float style air volume control valve. That's what the guage in the middle screws into. I just didn't realize it until someone here pointed it out. I apologize. I'm still kind of learning here myself. I need to look at my well pump and see if I can do the same thing and get rid of the tubing it has for the air volume control valve. It was my understanding that float style valve was for a submersible pump. Any reason why you can't use it on a jet well pump? Where the pump Is above ground and next to the tank?

So what do you do with the iron? Is there a drain at the bottom you can open up every so often?

I grew up in a house that had a shallow well, piston pump and a galvanized pressure tank. My Dad drained water out of the tank a couple times a year cause would get water logged and cycle the pump a lot. Crude by today's standards, but it worked.

It is caught by our two big (6'x36") Fleck filters and backwashed out every 24 hours.
