Water runs for about 2 minutes and the pump starts... I own a well-rite (wr120r)... The date on bottom sticker says April 31,1998... How do I adjust the pressures?

How large is the tank? The tank size will tell you how much drawdown you should be able to expect.

Never mind. You have a 34 gallon tank which should have a drawdown of about 12 gallons, depending on your cutin/cutout pressures. So, run water until the pump cuts on, then turn off the water and let the pump get up to cut off pressure. Now start running water into a 5 gallon bucket. Keep that up until the pump cuts back on. That will tell you what your drawdown is.

We go from there.
