The crew pulled this piece of well pump history out of a well in Rochester, NH the other day!

At first we had no idea what it was until we called our resident well water historian, Butch, who informed us that it was an in well pressure bladder.
These were popular back in the day when homes were using a jet pump and didn’t have the proper environment for a standard pressure tank.

Butch says he hasn’t seen one of these in 15 years! You never know what your going to find when out on the job.
