Is Your Well Pump Working Harder Than It Should This Summer?

You hear the pressure switch on your well pump click on while you’re rinsing dishes. A minute later, it clicks off. Thirty seconds after that, it clicks on again. You know this is happening more than usual, but you don’t know if it’s normal or if it’s a sign of trouble.

For homeowners in Maryland, Virginia, and West Virginia, the reality is that well pumps run more in July and August than in any other stretch of the year, and a busier pump doesn’t automatically mean your pump needs to be repaired or replaced.

The question is whether the extra work matches the extra water your household is using. 

Why Summer Puts Extra Demand on Maryland Well Pumps

Summer months bring increased water use for a number of reasons, including more frequent showers, lawn irrigation, pool maintenance, and gardening. The U.S. Environmental Protection Agency puts outdoor use at more than 30% of the average household’s total water use and reports that the typical American home uses more water outdoors than for showering and laundry combined.

Aquifer levels are also an issue. They are at their lowest in late summer due to minimal rain and heavy evaporation, waiting to be replenished by fall and winter precipitation. When the level in the well drops, the pump has to lift water a greater distance, draw more current, and run longer to build the same pressure, even though nothing about the pump or the house has changed.

So a pump running more often in hotter months is expected, to some extent. Yet, concerned homeowners can watch and listen for signs that their pump is working too hard to meet demand.

Normal Seasonal Demand vs. a Pump Under Strain

The following table shows expected summer load versus signs the pump is struggling.

Indicator	Normal Summer Demand	Sign of a Struggling Pump
Run Frequency	More cycles than winter	Constant or very short cycles
Water Pressure	Steady throughout the home	Fluctuating or noticeably lower
Run Length	Longer during irrigation or peak use	Long runs even during light use
System Sound	Normal motor hum	Grinding, clicking, or louder than usual
Pressure Recovery	Returns quickly between uses	Slow to recover after demand
Water at the Tap	Steady flow	Sputtering or spitting air

A pump running more because the household is using more water is doing its job. A pump cycling constantly, producing inconsistent pressure, or drawing more current than the water output justifies is telling a different story.

What To Listen and Look for at Home

Most homes in our service area run a submersible pump that sits below the water line down inside the well casing. In this setup, the pump is likely too far away to hear from inside the home. What reaches you in the house is more likely the pressure switch clicking and water entering the tank. 

Homes with an above-ground jet pump can often hear the motor directly, usually from the basement or a well house.

A healthy pump cycle has a rhythm. The switch clicks on, the pump runs long enough to fill the pressure tank, the switch clicks off, and the system stays quiet for a while. How long that quiet lasts depends on tank size and how much water the house is pulling. 

One concerning behavior to notice is a switch that clicks back on within a few seconds of shutting off. That’s short cycling, and it means the pump is starting more often than the system was designed to allow.

Slow recovery is another issue that homeowners can watch for. If you turn on a tap right after the dishwasher or the washing machine finishes and the pressure feels weak, your pressure tank may be taking too long to recover.

If the pump turns on even though every fixture in your home is off and has been off for a while, that can mean the system isn’t holding pressure. You may be losing water somewhere between the well and the home.

How Your Pressure Tank Affects How Hard the Pump Works

A pressure tank holds a cushion of compressed air above a bladder that’s full of water. That air cushion pushes stored water into the house between pump cycles and lets the pump rest. If that air cushion is lost, the pump has to work harder to deliver water.

A tank that loses its charge of compressed air, usually due to a failed bladder, is said to be “waterlogged.” A sign of a waterlogged tank is inconsistent pressure, especially if the pressure loss is noticeable as soon as the pump shuts off. This causes the switch to call for the pump again, and the motor will restart many times more than necessary. 

Those rapid restarts generate heat the motor can’t shed, and heat is what eventually takes out the motor’s windings. Leave a problem like this alone long enough and instead of a simple fix such as recharging the pressure tank’s air bladder, you also have to replace the pump itself.

An undersized tank has a similar issue. It may handle an ordinary weekday, but the demand of a summer afternoon might empty the tank more often than the pump is designed to refill. This forces the motor to restart more often than it would in a system with a properly sized tank.

When Your Well Can’t Keep Up With Summer Demand

Sometimes the pump is healthy, the tank is fine, and the house is simply asking for more than the system was built to give. A conventional well setup is designed to supply a limited number of fixtures at once. Add a bathroom, a family member, or an irrigation zone, and the original design no longer matches the way the home actually uses water.

For wells that meet the parameters for the upgrade, a constant pressure system can solve issues of inconsistent pressure. Rather than cycling between a cut-in and a cut-out point, the pump in a constant pressure system varies its speed to hold pressure steady.

For wells that don’t meet those parameters, a booster pump added to the existing setup raises pressure instead. Booster pumps also work in homes on municipal water, which comes up more often than you’d think at the far end of a supply line.

When To Call for a Well Pump Assessment

You should expect a pump to run more often after changes to the house, such as adding a new irrigation zone to the lawn or having more people in the home taking showers and doing laundry. A pump that behaves differently when nothing about your water use has changed should be checked by a professional.
