Anyway, I find a tap there quite useful. After that, all you do is look at the pipe diameters you currently have and look at the opening diameters of your new tank and get all the pieces to fit. Ask the hardware guy for advice if you need to. Use 2 layers of teflon tape on all threaded connections and I think you are good to go.

I re-did my entire system but kept the pressure tank with no problems and I agree with what Optsy says, except I do have one question. I thought you could always replace a bladder tank with a diaphragm tank, and the diaphragm tank is superior?
Or is that marketing hype? Is there a benefit over using a bladder vs. A bladder tank uses a bag-type membrane that is subject to creases and folds. This can lead to reduced drawdown and trapped sediment. A diaphragm operates in a uniform and repeatable motion, promoting full drawdown and a clean water reservoir. Find all posts by zoesdad. So it took some cutting soldering etc. In other words, my setup was non-standard, not like the setup below.
I think the picture on the following link shows the standard kind of setup, I believe the other guys here would agree.

That silver colored object near the tank is a union and that is what you are supposed to open with wrenches to replace the tank. If your setup is like that then you have it made except for the cost of the tank. I think as the guys are saying, the bigger the pressure tank the better for the life of the pump. Apparently start-stops are tough on the pump. I think pump manufacturers recommend that your pump run for a least one minute when it starts. Anything else is too short. But I think you would look at a number as a minimum size tank, bigger is not worse. I think the diaphragm is the one you want.
How to choose and replace Well Water Pressure Tank
I usually think of them as the same but I believe there is a difference. Whether it is a big difference, I cannot say. Everyone has been giving you amazing help, I only have one simple thing to add to the check list before you change to a bigger tank.. My question first is how long has the problem been happening.. We are in the beginning of summer now, that is the only reason I mention this.
I hope this helps even a little bit, good luck on your well pump. Let me know how things go! Find all posts by nicktools Boy, am I glad I reached out to you folks for advice I'm going to spend some more time on this in a couple of days and can post a picture. Most set ups have a pressure guage that you can read. If you have one on your current set up just watch it closely and see what pressure it gets to when the pump kicks on.
That is your cut-in pressure. You may not be able to read it closer then 1 or 2 psi of accuracy.

If you see that it is somewhere between 18 psi and 20 psi, for example, then set your air at 16 psi. You don't want that air pressure of your tank above the cut-in pressure of your pump. If you are much lower, like 15psi for air pressure on a 20 psi cut-in, it just means that you will get a gallon or so less water from the tank between cycles. Not as big a problem as if you were 5 psi above the cut-in pressure.
At that level, your pump may start doing some wanky things. You might think that your pump just smoked some crack or something. If you don't have a pressure guage on your system, you can try to measure the air pressure of your current tank just when the pump kicks on, but that is quite difficult. You would need to be at the ready, once the pump kicks on, kill its power and then measure the air pressure in the tank at the Schrader valve. Not a very accurate system and then I would want to subtract a few PSI so I don't make that crack mistake, I alluded to above. Subtracting PSI air pressure in the tank is the same as subtracting a lot of useful water, so it is best to have a pressure guage on your system so you can get as accurate as possible.
In zoesdad's post you see the type of guage I am talking about. Just a standard round guage with a dial on it. If you don't have a pressure guage you can just add one when you set up the new tank.
What Is A Pressure Tank?
Since you won't know your cut in pressure, just put the air at something fairly low, like 15 psi I doubt your pump kicks on below 15 psi. Turn on the system, fill the tank and let it switch off. Now with the new guage take your reading for the cut in. Now turn off the pump and empty the tank. Add air to the tank until you read 2 psi below that cut in number you just read. Now turn on the pump, refill the system and you are set to go.

This can't be an accurate reading, right? As far as I can tell the current tank does basically nothing Here are the pictures It keeps the water from going backwards towards the well. It allows water to flow in one direction. The valve with the green handle is a shutoff valve to shut off the water to your house. I think all new installations need them today.
How Does A Pressure Pump Work?
They are for safety because as I understand it, if there is a failure the pump has the capability to really put a lot of pressure into the system. Shut off the power to the pump b. Shutoff the water to the house green handle c. Open the boiler drain blue handle and drain the tank. Open the union and move out the tank.

Put the new tank in place and tighten the union see note 1 below f. Make sure the air pressure in the new tank is 2 psi below the cut-in pressure of your pressure switch. But as Optsy says to find the cut-in pressure: Thus you could close the 2 ball valves you see with the red handles, and then open that union and take the entire sediment filter out by unscrewing things. And if you wanted to you could supply unfiltered water to the house while having fun with the sediment filter or replacing it with a new one, by opening up that vertical ball valve with the other 2 ball valves closed.
Yeah, zoesdad gave a great description. That square plug to the left of the green tap is probably for the pressure relief valve that someone was going to get around to buying Anyway, I doubt the system is putting out psi. If your current tank has a Schrader valve on the top you could measure it with water in the tank. If the tank was operating properly the air pressure will equal the water pressure since it is the air that effectively delivers all pressure.
All this step will do is maybe confirm if your guage is working right. Eventually you will need a working guage. They are not that expensive and are pretty easy to replace, if you find you need to. Just turn off the water and drain any tank and pipes above it. Unscrew the current one. Add two layers of white Teflon tape to the new one and screw it in tight. Other then that you have a very nice looking set up. I took from your post that you were not sure what the filter system was. That kind of tells me that you are not changing that filter All pressure pump systems need a check valve or 1 way valve installed in the pipework.
This can be installed on the suction side as a foot valve or on the pump inlet or just after the pump on the outlet. The check valve stops water flowing backwards and the pressure dropping when the pumps turns off. This allows a pressure pump to build up pressure and let the automatic switch turn it off. A pressure tank can be installed anywhere after this check valve.
This means that when all the taps in the system are shut, then the pressure in the system builds. When the water pressure in the system builds to beyond the air pressure sored in the tank, then the air starts to compress and the water fills up the wet side of the tank. Once the wet side of the tank has compressed the air as much as it can, then the pressure builds a little bit more and then switches off.
You simply cut in a T piece or a tapping saddle into the outlet pipework and have a pipe or a piece of pressure hose across to the inlet of the tank. Some tanks up to about 15L are OK to mount on the pipe or on top of the pump. Once they get beyond this size, they usually have to be mounted on a base and most of the time they actually come with a base. Pressure tanks are a cheap, simple and effective piece of gear that will help protect your pump and provide you with a good constant pressure and flow of water for whatever application you need.
