Water pressure that surged, then dropped to a trickle. A well pump that seemed to run nonstop, even with every faucet off. Here's how we traced it to a failed pressure tank — and got the whole system back to normal in a single visit.
The homeowner's first clue was the water pressure itself — strong for a few seconds, then weak, then strong again, cycling almost like a heartbeat every time a faucet ran. Then came the sound: the well pump kicking on and off every minute or two, even overnight, with nothing in the house drawing water.
On a private well system, that pattern points to one place — the pressure tank. A healthy tank holds a cushion of pressurized air that lets the pump rest between draws. When the tank's internal bladder fails, that cushion disappears, and the pump is forced to switch on almost every time a single drop of water moves through the pipes. Left alone, that kind of short-cycling burns out well pumps fast — often the more expensive part to replace.
Our technician started at the tank itself, checking the air pre-charge and tank pressure against the pump's cut-in and cut-out settings. The pre-charge had collapsed to almost nothing, confirming a ruptured bladder rather than a wiring or pump issue. We also checked the pressure switch and pump run time to rule out a second problem stacking on top of the first — everything else in the system checked out fine.
With the diagnosis confirmed, we walked the homeowner through the options: repair versus full tank replacement, and what each meant for the age of their system. They chose to replace the tank outright, given its age, rather than risk another failure soon after a repair.
"Our water pressure had been driving us crazy for weeks and we thought the whole well pump was dying. Turned out it was the tank, and they had it swapped out the same afternoon. Water pressure's been rock solid ever since, and the pump isn't running constantly anymore." — Homeowner, Prior Lake, MN
The home went from surging, unpredictable water pressure and a pump running almost around the clock to a steady, properly pressurized system in one visit. The new tank now holds the air cushion the pump needs to rest between draws, which means less wear on the pump itself and a system built to last years longer without another emergency call.
That's the value of catching a failing pressure tank early: a tank replacement is a straightforward, affordable fix — a burned-out well pump from months of short-cycling is not.
Well water systems don't fail quietly — they show up as pressure that swings, a pump that short-cycles, or water that sputters and stops. If that sounds like what's happening at your place, whether you're in Prior Lake, Credit River, Elko New Market, or anywhere on well water around the metro, we can diagnose it and, in most cases, fix it the same day.
