Why Is My Water Bill So High? 7 Possible Causes for Ada, OK Homeowners

You open your City of Ada utility bill and immediately notice something isn't right. Your water usage is much higher than normal—but you haven't added anyone to the household, filled a swimming pool or knowingly used more water.
Why is your water bill suddenly so high?
An unusually high water bill can have several causes, but one of the most important possibilities to rule out is a hidden plumbing leak.
For homeowners in Ada, Oklahoma, here are seven common reasons your water usage may suddenly increase—and some simple ways to investigate the problem.
1. A Leaking Toilet
A leaking toilet is one of the first things to check when water usage unexpectedly increases.
Unlike a dripping faucet, a toilet leak can be surprisingly difficult to notice. Water may continuously escape from the tank into the bowl without making much noise.
Common causes include:
A worn or damaged flapper
A faulty fill valve
An improperly adjusted float
Water continuously flowing into the overflow tube
Aging components inside the toilet tank
How can you check a toilet for a leak?
One easy test is to put several drops of food coloring into the toilet tank without flushing.
Wait about 15–20 minutes. If colored water appears in the bowl, water is leaking from the tank into the bowl.
You can also listen carefully for toilets that periodically refill even though nobody has used them. That can be another sign that water is escaping from the tank.
A toilet that "runs every once in a while" may seem like a minor annoyance, but over time it can waste a significant amount of water.
2. An Underground Water Service Line Leak
A leaking underground water line can cause a significant increase in water usage, particularly because the leak may run 24 hours a day.
Your home's water service line carries water from the municipal water system to your house. Because most of this pipe is buried, a leak isn't always immediately visible.
Possible signs of an underground water-line leak include:
Unexplained increases in water usage
Wet or muddy areas in the yard
Standing water when it hasn't rained
An unusually green or fast-growing patch of grass
Reduced water pressure
The sound of running water when fixtures are off
Water appearing near the meter or elsewhere on the property
Don't assume that the spot where water surfaces is necessarily where the pipe is broken.
Water can travel underground before becoming visible.
If you suspect an underground leak, a licensed plumber can help determine whether the home's private water line is leaking and identify the appropriate repair.
3. A Dripping Faucet, Shower or Outdoor Hydrant
That slow drip may be using more water than you think.
A leaking kitchen faucet, bathroom faucet, shower valve or outdoor hydrant can continuously waste water. Multiple small leaks throughout a home can add up.
Walk through your property and check:
Kitchen and bathroom faucets
Bathtub and shower fixtures
Outdoor faucets
Yard hydrants
Utility sinks
Connections around washing machines and other appliances
Also look underneath sinks and inside cabinets. Some leaks don't drip into a basin where they're easy to notice—they leak into the cabinet or wall instead.
4. A Water Heater Leak
Your water heater is another place worth checking.
Look around the base of the water heater for moisture, corrosion or standing water. Also inspect visible plumbing connections around the unit.
Water heater leaks can come from several places, including valves, fittings and connections. In some cases, however, water leaking from the tank itself can indicate that the water heater has deteriorated and may need replacement.
Never ignore unexplained water around a water heater. Besides wasting water, a worsening leak can cause property damage.
If you're unsure where the water is coming from, have the unit inspected by a licensed plumber.
5. Irrigation Systems and Outdoor Water Use
Sometimes the explanation isn't inside the house at all.
Sprinkler systems, garden hoses, outdoor faucets and irrigation lines can significantly increase water consumption—especially during hot Oklahoma summers.
An underground irrigation leak can also be difficult to see.
Look for:
Broken sprinkler heads
Sprinklers watering pavement instead of landscaping
Irrigation zones that won't shut off
Soggy areas around irrigation lines
Leaking hose connections
Outdoor faucets that aren't completely closing
Also consider whether your watering habits have changed. A sprinkler system running several times per week can dramatically increase household water consumption compared with cooler months.
6. Your Household Really Is Using More Water
Not every high water bill indicates a plumbing problem.
Before assuming you have a leak, consider whether anything has changed recently.
For example:
Do you have guests staying with you?
Are children home more often?
Have you been watering your lawn or garden?
Have you filled a pool or hot tub?
Are you doing more laundry?
Have you been washing vehicles?
Has someone started taking longer or more frequent showers?
Seasonal changes matter, too. Oklahoma's summer heat can cause outdoor water consumption to rise substantially.
If there's an obvious explanation for the additional usage, your plumbing may be perfectly fine.
But if nothing about your household's water habits has changed, it's worth investigating further.
7. A Hidden Leak Somewhere in Your Home
Some plumbing leaks aren't visible at all.
A pipe can leak:
Inside a wall
Under a floor
Beneath a concrete slab
In a crawlspace
Underground between the meter and house
You may notice other clues before you ever see water.
Watch for unexplained dampness, stains on walls or ceilings, musty odors, warped flooring, reduced water pressure or the sound of running water.
A high water bill combined with one of these symptoms is a good reason to investigate quickly.
How Can I Tell If I Have a Water Leak?
Your water meter can provide an important clue.
Try this simple test:
Make sure nobody is using water.
Turn off faucets, showers and water-using appliances.
Make sure toilets aren't flushing or refilling.
Turn off irrigation systems.
Check your water meter.
Wait a period of time without using any water and check it again.
If the meter shows continued water usage while everything is turned off, you may have a leak.
The next challenge is determining where that leak is located.
Start with easy-to-check fixtures such as toilets and faucets. If you can't find the source, it may be time to call a plumber.
Is the City of Ada Responsible for My Water Leak?
That depends on where the leak is located.
Public water mains and City-owned infrastructure are generally handled by the City, while private plumbing serving an individual property is generally the property owner's responsibility.

If you're unsure whether a leak involves your private plumbing or public infrastructure, don't guess. The City of Ada or a licensed plumber can help determine where the problem originates.
Can the City of Ada Adjust My Bill After a Water Leak?
If a plumbing leak caused an unusually high water bill, keep your repair documentation.
The City of Ada has a process for certain leak-related utility bill adjustments. Eligibility requirements apply, so homeowners should contact Ada City Utilities directly to determine whether their particular leak qualifies.
An invoice from your plumber documenting the repair may be important when requesting an adjustment.
When Should I Call a Plumber About a High Water Bill?
You probably don't need to call a plumber simply because one bill is slightly higher than normal.
But consider having the plumbing inspected if:
Your water usage increased significantly without explanation.
Your meter indicates usage when everything is turned off.
You repeatedly hear water running.
You have unexplained wet areas in your yard.
You notice reduced water pressure.
You see moisture or water damage inside your home.
You've checked toilets and faucets but still can't explain the additional usage.
The sooner you locate an active leak, the sooner you can stop wasting water and reduce the possibility of property damage.
Frequently Asked Questions About High Water Bills
Why did my water bill suddenly double?
A sudden increase can result from increased household use, irrigation, a running toilet, leaking fixture or hidden plumbing leak. If your household habits haven't changed, check for leaks and monitor your water meter while all fixtures are turned off.
Can a running toilet cause a high water bill?
Yes. A toilet can continuously leak water from the tank into the bowl without being particularly noticeable. If a toilet periodically refills when nobody has used it, check it for a leak.
Can an underground water leak increase my water bill?
Absolutely. Because an underground service-line leak can run continuously, it can substantially increase water consumption before the homeowner realizes there is a problem.
How do I know if my underground water line is leaking?
Possible signs include unexplained water usage, wet areas in the yard, reduced water pressure, unusually green patches of grass or a water meter that registers usage while everything in the home is turned off.
Who fixes a water leak between the meter and my house?
A leak involving the property's private water service line is generally the property owner's responsibility. A licensed plumber can diagnose and repair private water-line leaks. If you're uncertain whether the problem is on private or City-owned infrastructure, contact the City of Ada for clarification.
