Summer usually means higher water use, but a dramatically higher water bill can signal more than extra showers or lawn watering.
For homeowners in Marietta, GA, the most common reasons for an unexpected summer water-bill increase include irrigation problems, hidden plumbing leaks, running toilets, leaking outdoor water lines, inefficient fixtures, and problems with the main water service line.
The key is determining whether your higher bill reflects normal seasonal use or water that is being wasted somewhere you cannot easily see.
Why Do Water Bills Increase During the Summer?
Most households naturally use more water during warmer months.
Summer water use may increase because of:
- Lawn and landscape irrigation
- Filling or topping off swimming pools
- More frequent showers
- Increased laundry
- Garden watering
- Washing vehicles
- Outdoor cleaning
- Children being home more often
A moderate increase may simply reflect a change in your family’s routine.
A large or unexplained increase, however, deserves attention.
If your household habits have not changed enough to explain the difference, water may be escaping somewhere in the plumbing system.
Start With Your Irrigation System
Sprinkler and irrigation systems can account for a substantial portion of outdoor water use during a Georgia summer.
Problems can remain unnoticed because much of the system operates automatically and many irrigation lines are underground.
Watch for:
- Broken sprinkler heads
- Sprinklers watering sidewalks or driveways
- Zones running longer than expected
- Irrigation systems operating too frequently
- Valves that continue allowing water through after the system shuts off
- Unusually wet areas in the lawn
- Areas of grass that are much greener than surrounding turf
- Water running into the street
- Low pressure in one irrigation zone
Walk through your property while the irrigation system is operating. Make sure every sprinkler head is working properly and water is reaching landscaping rather than pavement.
A small irrigation problem repeated several times each week can waste a surprising amount of water over the course of a billing cycle.
Check for Hidden Plumbing Leaks Inside Your Home
Not every summer water-bill increase originates outside.
Small plumbing leaks can continue twenty-four hours a day, making them particularly expensive over time.
Look for signs such as:
- Damp cabinets
- Water stains
- Moisture around plumbing fixtures
- Musty odors
- Peeling paint
- Bubbling drywall
- Unexplained sounds of running water
- Warm or damp areas on flooring
- Water appearing around toilets
- Persistent moisture near appliances
Some leaks are obvious.
Others occur behind walls, underneath floors, in crawlspaces, or beneath concrete slabs where homeowners may not notice them immediately.
An unusually high water bill may be one of the first indications that something is wrong.
Do Not Overlook a Running Toilet
A toilet does not have to overflow to waste water.
Internal components can allow water to continuously move from the tank into the bowl without attracting much attention.
Possible warning signs include:
- The toilet refilling when nobody has used it
- A faint running-water sound
- The fill valve cycling periodically
- Water constantly moving inside the bowl
- A toilet handle that sticks
- A tank that takes unusually long to refill
Because the problem may continue around the clock, a running toilet can contribute to higher water usage even when everything appears normal at first glance.
Outdoor Faucets and Hose Connections Can Waste Water Too
Summer means garden hoses, sprinklers, pressure washers, pool hoses, and other equipment are frequently connected to outdoor faucets.
Inspect hose bibs and connections periodically.
Look for:
- Faucets that drip when turned off
- Water leaking around the handle
- Loose hose connections
- Cracked garden hoses
- Leaking splitters or timers
- Water collecting against the foundation
- Moisture appearing behind the outdoor faucet
A small outdoor leak may seem insignificant, but continuous water loss adds up.
Leaks behind an exterior faucet can also be harder to notice because the water may travel into the wall rather than onto the driveway or lawn.
Your Main Water Line Could Be the Problem
Sometimes a high water bill points to a leak in the underground water line supplying your home.
Because the pipe is buried, the leak may not create an obvious puddle.
Possible warning signs include:
- A sudden unexplained increase in water usage
- Lower-than-normal water pressure
- Soggy areas in the yard
- Unusually green patches of grass
- Water appearing near the foundation
- Soil that remains wet during dry weather
- The sound of water running when fixtures are off
A pressurized underground water line can continue leaking whether anyone is using water inside the house or not.
Professional testing can help distinguish a main water-line problem from irrigation or indoor plumbing issues.
Check Your Water Meter
Your water meter can sometimes provide an important clue.
Turn off faucets, appliances, irrigation systems, toilets, and anything else intentionally using water.
Then check the meter.
If the meter continues registering water use while everything should be off, that may indicate water is escaping somewhere in the system.
This test does not tell you where the problem is located, but it can help determine whether further investigation is worthwhile.
Could Your Pool Be Increasing Your Water Bill?
Pools naturally require some replacement water because of evaporation, splashing, maintenance, and normal use.
But unusually frequent refilling may indicate a problem.
Watch for:
- A rapidly falling water level
- Persistent wet areas near pool equipment
- Dripping plumbing connections
- Water around pumps or filters
- Cracked fittings
- Equipment that repeatedly loses prime
- Air entering the circulation system
If you are adding substantially more water than usual, the cause deserves investigation.
Inefficient Fixtures Can Increase Water Use
Sometimes the plumbing system is not technically leaking, but older or poorly performing fixtures are using more water than necessary.
Fixtures worth evaluating include:
- Toilets
- Showerheads
- Faucets
- Outdoor faucets
- Washing-machine connections
- Irrigation components
A fixture that no longer operates correctly may require longer use or allow water to continue flowing when it should not.
Repairing or replacing problematic plumbing components can improve performance while reducing unnecessary water consumption.
How Professional Leak Detection Finds Hidden Problems
When there is evidence of water loss but the source is not obvious, professional leak detection can narrow down the problem without randomly opening walls or floors.
Depending on the situation, a plumber may use methods such as:
- Pressure testing
- Acoustic leak-detection equipment
- Thermal imaging
- Plumbing-system isolation testing
- Camera inspection where appropriate
- Physical inspection of fixtures and plumbing connections
The objective is to determine where the water is going before unnecessary repairs are performed.
That distinction matters.
A high bill caused by an irrigation valve requires a very different repair from a leaking supply line underneath the house.
What Should You Do After Receiving an Unusually High Water Bill?
Do not immediately assume the increase is simply because it is summer.
Start by comparing the new bill with previous months and ask whether your actual water habits changed enough to explain the increase.
Then:
- Check toilets for continuous running.
- Inspect sinks, cabinets, and visible supply lines.
- Check outdoor faucets and hose connections.
- Run the sprinkler system and inspect each zone.
- Look around the yard for unusual wet areas.
- Evaluate whether the pool requires more refilling than normal.
- Check the water meter while water fixtures are turned off.
- Contact a plumber if you still cannot identify the source.
The faster an unexplained water-loss problem is identified, the less water is likely to be wasted.
When Should You Call a Plumber About a High Water Bill?
Professional plumbing evaluation makes sense when your water bill is significantly outside its normal pattern and you cannot explain the increase.
You should also consider scheduling service when you notice:
- Persistent damp areas
- Unexplained water sounds
- Lower water pressure
- Repeatedly running toilets
- Wet areas in the yard
- Water near the foundation
- Signs of moisture behind walls or floors
- A water meter showing usage when everything is off
A plumber can evaluate the system and determine whether the problem involves a fixture, irrigation connection, hidden supply leak, or main water line.
Frequently Asked Questions About High Summer Water Bills
Why did my water bill suddenly increase?
A sudden increase can result from greater household water use, irrigation, pool use, running toilets, leaking fixtures, underground plumbing leaks, or a damaged water service line.
If your daily habits have not changed enough to explain the increase, investigate for possible water loss.
Can a running toilet really increase my water bill?
Yes. A toilet that continuously allows water to move through the tank can waste water throughout the day and night without overflowing or creating an obvious leak.
How can I tell if I have an underground water leak?
Warning signs may include unexplained water usage, wet or unusually green sections of lawn, reduced water pressure, or continued meter activity when fixtures are turned off.
Can sprinkler systems cause high water bills?
Yes. Incorrect schedules, leaking valves, broken sprinkler heads, damaged underground lines, and excessive watering can all increase outdoor water consumption.
Should my water meter move when everything is turned off?
When absolutely no water is intentionally being used, continued meter activity may indicate water is flowing somewhere in the plumbing system. A plumber can help determine the cause.
Can professional leak detection find leaks without tearing up my house?
Many hidden leaks can be narrowed down using diagnostic techniques such as pressure testing, acoustic equipment, thermal imaging, and other targeted methods before invasive repair work is considered.
Stop Paying for Water You Are Not Using
A higher summer water bill may simply reflect more outdoor activity, but a significant unexplained spike should not be ignored.
Checking your irrigation system, toilets, outdoor faucets, plumbing fixtures, water meter, and yard can help identify obvious problems.
When the source remains hidden, professional leak detection can determine where water is being lost and what repair is actually necessary.
