Pressure Tank Service in San Antonio
The pressure tank is the least glamorous part of a well system and the one most often ignored until it takes the pump with it. On deep Hill Country wells where a replacement pump runs several thousand dollars, a failed tank is an expensive thing to leave alone.
What the tank actually does
It holds a cushion of pressurised air against a bladder so that small draws — a tap, a toilet refill — come out of stored pressure instead of starting the pump. When the bladder fails the tank waterlogs, the cushion disappears, and the pump starts and stops every few seconds.
Motor start-ups are what wear a submersible out. A waterlogged tank can turn a fifteen-year pump into a five-year pump, and at Trinity depths that is a difference of thousands of dollars.
Symptoms worth acting on
- Pump switching on and off rapidly while water runs
- Pressure swinging noticeably at the tap
- Tank sounds solid when tapped near the top
- Water spitting or surging from fixtures
Replacement runs $500 to $1,400 installed. If you are already being quoted for a new pump, insist the tank is tested at the same time.
Frequently Asked Questions
How do I know if my pressure tank is bad?
Tap it. A healthy tank sounds hollow in the upper portion and solid at the bottom. If it sounds solid all the way up it is waterlogged. The other clear symptom is the pump switching on and off every few seconds when water is running.
Why does a bad pressure tank kill the pump?
The tank buffers demand so the pump does not start for every small draw. When the bladder fails, the pump cycles constantly, and motor start-ups are what wear a pump out. Replacing a pump without fixing the tank means replacing the pump again.
What does a pressure tank cost in San Antonio?
$500 to $1,400 installed depending on tank size and how accessible the location is. It is by a wide margin the cheapest way to extend the life of an expensive deep-well pump.
