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.
The bladder.
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.
In this case the only proper thing is to get a new bladder tank.
If tank has rusted through, tank will leak. If bladder goes bad, tank should not leak.
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.

The "bladder" in a bladder water tank is typically made using a durable, puncture resistant fabric that is made to withstand pressure and prevent the pillow from popping.
bleed the air tank by pushing down on the air stem, remove the pressure from the water tank,add correct amount of air to bladder, then start pump.
depending on many different situations, your bladder in your pressure tank can be broke and it can still work if your pressure tank is vertical with inlet down and your bladder just has a hole or crack in it. Most of the times however with a damaged bladder the pre pressurized air inside the tank will over time leak into the water system and then your pressure tank will not work properly. Sometimes on pressure tanks that sit vertical and have a ruptured bladder the pieces of the bladder clog the inlet/outlet thus making the pressure tank fail and it can be a pain if its a bigger pressure tank to remove because it will not drain out the water. Most pressure tanks have a air inlet on top or opposite side of the water inlet/outlet and should always be precharged of air pressure psi depending on the amount of water pressure like example 15-18 air psi if water system is running at 55-60 psi. One way to find out if your bladder is broke or precharged in your pressure tank is to drain the water pressure out then put a air gauge on the air fitting of the tank and see if it has pressure.
Depends on what you consider better? If a bladder fails you need to rush out and get a new one if a galvanized tank gets floooded you can drain it and your back in business
if its a bladder type tank, it will need to be replaced
Not necessarily. Most bladder tanks will work up to 80 PSI and most homes on well systems don't go higher than 60 PSI. If your bladder tank, pump and pressure switch are all in good shape then you can raise the pressure easily by adjusting the pressure switch and pumping more air into the tank. tank should have 28 or 38 psi residual air - pressure switch 'on' should be 2 PSI higher than tank. - If your pressure has been getting lower, then it's possible the bladder is losing air. If this is the case you can pump air in to help temporarily till a new tank is fitted.
