Short cycling. NEED HELP ASAP

Learned my pressure control switch has been short cycling: sometimes from on to on 5 seconds and sometimes on to on 20 seconds. Found this out when I lost water and checked on the system--the pressure control switch had shut off. A nudge to the switch and it turns back on but short cycles anytime the water is being used. In checking the pressure on the tank with a tire gauge, water spewed out the stem. I guess this means the bladder ruptured. The pressure gauge is also out of whack. All said and done, I think I should replace the precharged tank, the pump pressure control switch, the gauge and add a pressure relief valve. Currently, I have a precharged Flotec, 220 gallon equivalent. Can I change it out for a 35 gallon/82 gallon equivalent precharged Flotec? The submersible pump is a three wire 4" Flotec. Because it has been so many years since installing the pump, I have no recollection as to what Hp I have. The well as 32 gallons per minute and the well depth is 215. The system was installed in 1994. Need an answer quickly as I will be purchasing the parts tomorrow, Thursday, July 15, as this has been going on at least one week and I need to replace the parts before my pump burns up. Please answer my questions in simple terms. I am not a plumber, just a woman trying to get by. Thank you. Dani

Yes you need a new tank. The bladder busted from too much cycling. Then the pump has been damaged from regular cycling and now the rapid cycling of a bad tank. Putting in a smaller tank will stop the rapid cycling, but more than double the regular cycling. A CSV will stop the cycling and allow you to use an even smaller tank if you like. The picture to the left is how I would replace it. With a CSV the 4.4 gallon tank is plenty. Without a CSV I don’t think a 220 equivalent is large enough. One of these kits http://www.cyclestopvalves.com/st-viewcat.php?cid=26 has everything you need.
