A bladder water tank has an air or water-filled piece of rubber inside the water tank. When the water is used, the pressure inside the tank changes, sending an electrical signal to the water pump to refill the water tank, and then sends another signal when it's time to shut of..
Bladder water tanks are relatively durable, however they will not last as long as steel and other metal water tanks. They are very favorable, however, for when you need your water tank to be mobile, as they are easy to transport.
Bladder water tanks contain a rubber bladder from which the water is used. As the water pressure goes down it turns on a switch which causes the water bladder to be refilled from the attached well.
Bladder water tanks are used under houses and mobile homes and act as a water tank but is like a giant balloon instead of a solid tank. As it fills with water the tank gets bigger.
Water bladder tanks are tanks which contain a rubber bladder that is filled with either water or air. The majority of water bladder tanks have water-filled bladders. When a water faucet is turned on or a toilet is flushed, the water is piped in from the water tank. As the water pressure and air pressure get low, the contacts on the pressure switch click together. The pressure switch sends an electrical current to the water pump which causes the water pump to kick on and pipe water back into the water bladder tank. The amount of time it takes for the pressure switch to click on depends upon the size of the water bladder tank. The larger the water bladder tank, the longer it will be before the pressure switch starts to deliver electrical current to the water pump.

Defective bladder / low pressure inside the tank
bladder tanks are much better for the pump and will be fine as a replacement.

depending on the brand name of your pressure tank and what kind of bladder material they used but most larger pressure tanks need to be vertical so the bladder expands equally. I would check with your pressure tank manufacture.
All bladder tanks (unless very small) have a way to fill the bladder bag. Depending on what you are using this for you may need a bigger bladder tank.
From what?ANS 2 -Defective bladders are quite common when tanks are 10 or more years old. -On most tanks over 50 gal or so, the plate on base where incoming water is connected, can be unbolted. BEFORE doing this, MAKE SURE you can get a new bladder ! - Not all tanks companies will sell just the bladder, and some make them so expensive you may as well buy a new tank ! When this is done, just pull out the old bladder and carefully insert the new one. -I've done this on many tanks bigger than 120 gal - you have a large hole to work with there. Smaller tanks are not so easy.
Fish have an gas-filled, internal swim bladder, whose buoyancy they regulate to keep from sinking or rising in the water.
NOT lungs, but bladders, yes. Most new style well pressure tanks have a large tough balloon known as the bladder to contain the water as it's pumped in from the well. This bladder will expand to fill about 2/3 of the tank volume. The other third is the air charge, usually of 28psi. It is this air charge that gives the water it's pressure, and as the water depletes through normal usage the pump will switch on at 30 psi and refill the tank. (It's vitally important to balance the tank air pressure and the pressure switch settings.) These bladders can become pinholed through long use and often bleed water into the air chamber and slowly become useless as there is less water pressure. Bladders in tanks over 120 gallon can be replaced, smaller than that is possible, but not cost effective.Older style tanks, called 'galvanised tanks' did not have a bladder, and once the tank contained a small amount of water, a compressor is used to install 28 psi of air charge. The disadvantage of these is obvious when power outages occur and people use water and deplete the air charge because the pump does not switch on. When power returns there is no, or very little water pressure. (in a good bladder tank this will not happen as the air charge is separate.) Under this condition, the pump will operate for a very short time every time a faucet is opened or a toilet flushed, leading some people to think they have a pump problem. I have known unknowledgable people, and even some plumbers to have bought and fitted a new pump, when all it needed was an air charge. -This is why bladder tanks were invented.
