Our old well tank rusted out on the bottom and has been replaced. Now we have a lot
Of air in the lines. We shut off the well and bleed the lines and the pressure stays good
For a day or two, and then it starts sputtering and growling in the lines again.

This could be caused by a lowered water table and you're sucking air or a leak in the suction line. Have you calibrated the new bladder tank to your system? If not click on back for instructions. Regards, Tom
