Frequently Asked Questions
How much does pressure tank replacement cost in Maryland?

How do I know if my pressure tank needs to be replaced?
The most common sign is short-cycling — the pump runs every 30 seconds or less. Tap the tank from bottom to top: a healthy tank sounds hollow in the upper portion; a waterlogged tank sounds solid throughout. Check the Schrader valve: if water comes out instead of air, the bladder has failed.
How long does a pressure tank last?
A quality pressure tank should last 10–15 years with normal use. Tanks fail early when water quality is poor — high iron fouls the bladder, and acidic water corrodes the tank shell. Treating your water extends tank life significantly.
