I work on maybe 5-10 wells a year. Mostly replacing pumps, tanks, or switches. The up and down pressure is the biggest complaint I hear. The addition of a pressure regulator in the other thread got me to thinking. Are there any drawbacks to doing this? If I were to add a regulator and set the pressure at 50# with the tank and switch set at 50-70 are there any problems that this would cause. I know an older tank bladder might burst by changing the pressure. How about a shorter pump life? Talk to me.
