The telltale sign is a pump that turns on every few seconds while water runs. Tap the tank: a bad bladder tank sounds full of water from top to bottom. With the pump off and the system drained, press the air valve. Water coming out, or no air, means the bladder has failed. Our bad pressure tank guide covers the other signs.

Well Pressure Tank Replacement in Weatherford, TX
A pressure tank that has lost its air charge makes the pump start every few seconds. Fixing it early is the cheapest way to protect a $2,000–$4,000 pump.

Water Well Drilling Weatherford handles well pressure tank replacement for homes across Parker County. It’s one of the cheapest jobs we do, and it protects the most expensive part of the system. The tank stores pressurized water so the pump doesn’t have to start every time someone opens a faucet. When the bladder inside fails or the air charge leaks away, the tank fills with water and stops doing that job. The pump then starts and stops every few seconds.
Why short cycling kills pumps
Submersible motor makers call for at least a minute of run time every time the pump starts, so the heat from the starting current can dissipate. A waterlogged tank can cut that to a few seconds, dozens of times an hour. Each start heats the windings and wears the switch contacts. Left alone, a failed tank usually leads to a failed pump. The tank costs a few hundred dollars; replacing the pump and motor at Parker County depths typically costs $1,800–$4,500.
Choosing the replacement
- Bladder or diaphragm tanks are the standard today. The air and water are separated, so the tank holds its charge for years.
- Old galvanized tanks without a bladder need air added regularly. Most are worth replacing outright.
- Size is set by the pump, not the old tank. If the old tank was undersized, the replacement should be bigger.
- Location matters in Parker County summers. A tank in an unshaded, unvented well house runs hot, which shortens bladder life.
Pre-charge and settings
The tank’s air pre-charge is set 2 psi below the pump’s cut-in pressure with the system drained. On a common 40/60 switch, that means 38 psi. If the pre-charge is wrong, even a new tank delivers less water per cycle than it should. We set it, fill the system, and time several pump cycles to confirm the pump runs long enough each time it starts.
When pressure problems aren’t the tank
If the pressure is low but the pump isn’t cycling fast, the tank probably isn’t the problem. Look instead at a clogged switch port, a sediment filter that needs changing, a leak between well and house, or a pump that is wearing out. See low water pressure on a well for how to tell them apart.

How well pressure tank replacement works, start to finish
-
Confirm the cause
We drain the system and measure the tank's air charge. A tank that won't hold air, or water at the air valve, means a failed bladder.
-
Size to the pump
The pump's gallons per minute sets the tank size. Roughly one gallon of drawdown per gpm gives the one-minute run motors need.
-
Replace and set
New tank, tee, gauge and switch go in, and the pre-charge and pressure settings are matched before water goes back in.
-
Time the cycles
We run the house fixtures and time the pump through several cycles to prove it now runs long enough per start.

Well Pressure Tank Replacement questions
How do I know if my pressure tank is bad?
How long does a well pressure tank last?
A quality bladder tank typically lasts 10 to 15 years. Short cycling from an undersized tank or a wrong pre-charge is the most common reason tanks fail early. Hard, iron-heavy Trinity water can also shorten the life of fittings and switches.
What size pressure tank do I need?
Allow about one gallon of drawdown per gallon per minute of pump output. A tank delivers roughly 30% of its nominal size as drawdown, so a 10 gpm pump needs about a 30–40 gallon tank to run a full minute per start. Our tank sizing guide has the full table.
How much does pressure tank replacement cost in Weatherford?
Most replacements run $800 to $1,800 installed, including the tank, fittings, a new switch and gauge, and labor. A larger tank or a crowded well house adds to it.
