Pump clicking on and off every few seconds? That's short cycling — and it's actively destroying your pump motor every time it happens. We diagnose the real cause and fix it, usually the same visit.
We prioritize short cycling calls — every hour counts
Every time your pump starts, the motor draws 3–7 times its normal running current. A pump that short cycles 30–60 times per hour is generating enormous heat and stress with almost no recovery time between starts. What feels like an annoying inconvenience is actively burning out your motor. Most pumps that fail from short cycling could have been saved with a same-day pressure tank repair.
Short cycling has a very specific signature — once you know what to listen and look for, it's unmistakeable:
Short cycling always has a root cause — and the fix depends entirely on which one it is. This is why diagnosis matters. The wrong repair wastes money and leaves the real cause untreated.
Your pressure tank contains a rubber bladder that separates compressed air from water. When the bladder fails, the tank fills completely with water and loses its air cushion. With no stored pressure, the pump must turn on every time even a drop of water is used — potentially hundreds of times per hour.
How to suspect it: tap the tank — a healthy tank sounds hollow in the upper half. A waterlogged tank sounds solid all the way up. The fix: pressure tank replacement, which most often resolves the short cycling immediately.
The pressure switch controls when your pump turns on (cut-in pressure) and off (cut-out pressure). If the differential between those two settings is too narrow — or if the switch contacts are worn — the pump never achieves enough pressure to stay off before it's triggered to restart.
How to suspect it: short cycling that started suddenly rather than gradually, especially if the pressure tank checks out as healthy. The fix: pressure switch calibration or replacement — often an inexpensive repair.
If there's a leak anywhere in your pressurized water system — a dripping fixture, a leaking toilet flapper, a crack in a fitting, or a leaking check valve — pressure drops continuously even when no water is intentionally being used. The pump keeps restarting to restore pressure, cycling constantly to compensate for the loss.
How to suspect it: short cycling that happens even when all faucets are off. Turn everything off and watch the pressure gauge — if it keeps dropping, there's a leak. The fix: locate and repair the leak.
The check valve sits at the pump and prevents water from flowing back down into the well after the pump shuts off. When it fails, water drains back every time the pump stops — causing pressure to drop immediately, which triggers the pump to restart almost at once.
How to suspect it: pressure builds normally, pump shuts off, but pressure drops steadily over 30–60 seconds even with no water running. The fix: check valve replacement during a pump pull.
This is why we treat short cycling calls with the same urgency as a no-water emergency. The damage accumulates fast — and it's entirely preventable.
Each rapid restart generates a heat surge in the motor windings. With short cycling, the motor never cools between starts. Internal temperatures climb well beyond normal operating range within the first day.
The start capacitor absorbs the high-current surge every time the motor starts. Designed for a few thousand starts per year, a short cycling pump may deliver that many in a single week — degrading the capacitor rapidly.
The insulation on the motor windings degrades under sustained heat and mechanical stress. Once insulation fails, the motor short circuits internally — and at that point, there's no repair option. The pump must be replaced entirely.
A pressure tank that needed replacement becomes a full submersible pump pull and motor replacement — a significantly larger job. The pressure tank problem that started it all still needs to be fixed on top of the pump replacement. Catching short cycling early is one of the most cost-effective decisions a well owner can make.
We never assume it's the pressure tank without checking. Every short cycling job starts with a full system diagnosis — because fixing the wrong thing wastes your money and your time.
We test the pressure tank air charge and bladder, inspect the pressure switch settings and contacts, check for system leaks, and assess the check valve — before recommending any repair. The cause determines the fix.
If the bladder has failed and the tank is waterlogged, we replace it. Most residential pressure tank replacements are completed in a single visit. We size the new tank correctly for your pump and household demand.
If the switch is the cause, we recalibrate the cut-in and cut-out pressures for the correct differential — or replace the switch if contacts are worn. Often one of the fastest and least expensive fixes for short cycling.
If a system leak is causing continuous pressure loss, we locate it and repair it. We test the full system under pressure with all fixtures closed to identify whether any leakage is occurring before and after the repair.
A failed check valve requires a pump pull to access and replace. If our above-ground testing confirms this is the cause, we handle the full extraction and reinstallation process with the pump correctly inspected along the way.
After every repair, we run a full system test — confirming the pump is cycling correctly, pressure builds and holds, and the system is stable before we leave. We don't consider the job done until we've verified the short cycling has stopped.
A few simple actions can slow the damage while you wait for service. And a few common mistakes can make things significantly worse.
