Pressure Tank Service in St George, UT
Pressure tank service in St George, UT. Signs of a waterlogged or failed tank, how it's tested and set, and why it protects your well pump.
The tank that protects your pump
Your pressure tank does quiet but important work: it holds a cushion of pressurized water so your pump doesn't have to start every time you open a tap. When the tank's air charge is lost or its internal bladder fails, the pump starts short-cycling — kicking on and off rapidly — and that rapid cycling is one of the fastest ways to wear out a motor. A failing tank often shows up as pressure that surges and drops, a pump that clicks on constantly, or water that pulses at the faucet.
Servicing the tank is far cheaper than replacing a pump worn out by cycling, which is why it's worth checking any time pressure feels off. If your symptoms are more about weak flow than cycling, our low water pressure diagnosis page is a better starting point.
What pressure tank service covers
A tank visit checks the whole pressure side of the system.
-
Check the air charge
With the system drained, we measure the air pressure in the tank and compare it to the cut-in pressure of the switch. A tank charged a couple of PSI below cut-in is what keeps your pump from cycling.
-
Test the bladder
We check whether the internal bladder is intact. A waterlogged tank — water where air should be — can't hold a cushion and needs recharging or, if the bladder has failed, replacement.
-
Inspect the switch and gauge
The pressure switch and gauge are checked for corrosion and correct cut-in and cut-out settings. Hard water and scale commonly clog switch ports over time.
-
Set and verify
We set the air charge, confirm the switch settings, and watch a full pump cycle to be sure pressure builds smoothly and the pump shuts off cleanly.
Local conditions and your tank
The hard, alkaline water throughout the St George area leaves mineral scale on switch contacts, gauge ports, and the tank's air valve, so pressure components here often need attention sooner than they would elsewhere. Sandy grit can foul a switch as well. These are small parts, but when they drift out of adjustment they make the whole system feel unreliable.
In the colder towns up the Virgin River — Toquerville, La Verkin, Virgin — a pressure tank in an unheated garage, shed, or well house is exposed to a hard winter freeze. A cracked tank or frozen switch line can take the whole system down. Part of servicing a tank there is making sure it's protected before winter. A tank problem can mimic a pump problem, so if yours keeps failing we'll also recommend a full well inspection to rule out a deeper issue.
Pressure surging or pump cycling?

Frequently asked questions
What does a waterlogged pressure tank feel like?
Pressure surges and drops quickly, and the pump kicks on and off every few seconds when you run water. That short-cycling is hard on the motor and should be addressed before it damages the pump.
Can I just recharge the tank myself?
If the bladder is intact, adding air to the right setting can fix it, but the charge has to be matched to the switch's cut-in pressure and set with the system drained. If the bladder has failed, air won't hold and the tank needs replacing.
How often should a pressure tank be checked?
Checking the air charge once a year is reasonable, and any time you notice pressure surging or the pump cycling rapidly. Hard water locally can shorten the life of the switch and valves, so a periodic look pays off.
Does a bad tank really damage the pump?
Yes. Without a working tank, the pump starts far more often than it should, and frequent starts are one of the leading causes of early motor failure.
