Leak Detection in Los Angeles: Signs, Causes, and When to Call a Plumber

Thu, 20 Aug 2026 20:38:38 GMT

Hidden water leaks can be a sneaky culprit costing you thousands

A water leak is not always as obvious as a burst pipe or water flooding across the floor. In many cases, leaks begin slowly and remain hidden behind walls, beneath floors, under sinks, or underground. By the time visible damage appears, the leak may have already caused significant water damage or wasted a substantial amount of water.

For homeowners and businesses in Los Angeles and surrounding communities—including Pasadena, Glendale, Burbank, Hollywood, and throughout Los Angeles County—knowing the warning signs of a water leak can help you address a plumbing problem before it becomes more expensive and disruptive.

We're fully licensed, bonded, and insured. And we've been in business for more than 100 years with thousands of satisfied customers .

What Are the Signs of a Hidden Water Leak?

Some plumbing leaks are easy to spot. Others can continue for weeks or months without being immediately noticeable. Paying attention to changes around your property can help you identify a potential problem.

Common signs of a water leak include:

An Unexplained Increase in Your Water Bill

If your water usage habits have not changed but your water bill suddenly increases, a hidden leak may be wasting water. Even a relatively small leak can add up over time.

The Sound of Running or Dripping Water

Do you hear water running, dripping, or moving through your plumbing when faucets and appliances are turned off? This can sometimes indicate a leak in a water line.

Damp Spots or Water Stains

Water stains on ceilings, walls, or floors should never be ignored. Discoloration, bubbling paint, peeling wallpaper, or unexplained dampness may indicate that water is leaking behind the surface.

Musty or Unusual Odors

Persistent moisture can create a damp environment and may eventually contribute to mold growth. A musty smell near a wall, cabinet, bathroom, or other area of the property may be a sign that hidden moisture is present.

Warm or Damp Areas on the Floor

An unexplained warm spot on the floor may indicate a problem with a hot water line beneath the slab or flooring. Damp carpeting, warped flooring, or soft areas can also indicate that water is leaking where it should not be.

Mold or Mildew Appearing in Unusual Places

Bathrooms naturally experience moisture, but mold or mildew appearing repeatedly in areas that should remain dry can be a warning sign of a plumbing leak. Hidden leaks can provide the moisture necessary for mold to grow.

Low Water Pressure

A sudden or unexplained decrease in water pressure can sometimes be related to a damaged or leaking water line. Other plumbing issues can also cause low pressure, so a professional inspection may be necessary to determine the source.

Puddles or Wet Areas Outside

Water collecting in your yard when irrigation is not running may indicate an underground water leak. This is especially important to investigate if the affected pipe supplies an irrigation system, pool, outdoor fixture, or another water source.

What Causes Water Leaks?

Water leaks can occur for many reasons. Plumbing systems experience years of use, changes in water pressure, temperature fluctuations, ground movement, and normal wear and tear.

Some common causes include:

Aging or deteriorating pipes
Corrosion
Loose or damaged plumbing connections
Worn seals, washers, or valves
High water pressure
Damaged supply lines
Cracked drain pipes
Shifting soil or ground movement
Tree root intrusion affecting underground plumbing
Improper installation or previous repairs
Freezing temperatures in areas where pipes are exposed

In an older property, aging plumbing components can become more vulnerable to leaks. Even newer plumbing systems can develop problems when fittings fail, pipes are damaged, or excessive pressure places stress on the system.

What Are the Most Common Sources of Water Leaks?

Leaks can develop almost anywhere water travels through a property. Some of the most common sources include:

Toilets

A toilet may leak from the supply line, shutoff valve, tank, wax ring, or other plumbing components. Some toilet leaks are obvious, while others can remain hidden behind or underneath the fixture.

Faucets and Sinks

A dripping faucet is easy to notice, but leaks under the sink can go undetected inside a cabinet. Loose drain connections, damaged P-traps, worn seals, and deteriorating supply lines can all allow water to escape.

Showers and Bathtubs

Shower valves, drain assemblies, pipes, and surrounding plumbing connections can all develop leaks. Water damage may occur behind walls or beneath flooring before the problem becomes visible.

Water Supply Lines

Flexible supply lines connected to toilets, faucets, appliances, and other fixtures can wear out or become damaged. A slow leak may begin with only a few drops of water but continue to cause moisture damage over time.

Water Heaters

Leaks around a water heater may result from fittings, valves, supply lines, or the tank itself. Because water heaters hold a significant amount of water, problems should be addressed promptly. Unforeseen floods can wreak havoc on a home and cost a large sum of money to repair if they burst or flood. We are water heater experts for more than 100 years!

Appliances

Dishwashers, refrigerators, washing machines, and other appliances may have water supply lines or drain connections that can leak.

Underground Water Lines

Leaks beneath the ground can be especially difficult to identify because the damaged pipe is not visible. These leaks may affect irrigation systems, swimming pools, water supply lines, or other underground plumbing.

Professional leak detection can help identify the source before excavation or repairs begin. Depending on the location and type of leak, the repair may involve accessing the damaged pipe, removing the affected section, and completing a thorough repair.

What Harm Can a Water Leak Cause?

The longer a leak continues, the greater the potential for damage. What begins as a slow drip can eventually become a much more costly plumbing problem.

Water leaks may cause:

Damage to walls, ceilings, flooring, and cabinets
Warped or deteriorating building materials
Mold and mildew growth where persistent moisture is present
Damage to personal belongings or business property
Higher water bills and unnecessary water waste
Damage to landscaping or soil erosion from underground leaks
Structural concerns if significant water damage is left unaddressed
Disruption to your home or business during more extensive repairs

A small leak does not always remain small. Addressing the source early can often help prevent additional damage and reduce the scope of repairs.

When Is It Time to Call a Plumber?

It is a good idea to call a plumber when you notice signs of a possible leak and cannot identify or safely repair the source yourself. Prompt professional attention is particularly important when water is actively leaking, damage is spreading, or the source is hidden behind a wall, beneath a floor, or underground.

You should consider calling a plumber if:

Your water bill has increased unexpectedly
You see unexplained water stains or damp areas
You smell persistent musty odors
You hear water running when everything is turned off
Water pressure suddenly changes
You discover water beneath a sink, toilet, appliance, or water heater
You see unexplained puddles or wet areas in your yard
You suspect a slab or underground leak
You have recurring leaks or repeated water damage

The goal is not simply to stop the visible water. A proper repair should identify the actual source of the leak and address the underlying plumbing problem. Call us today and request a free estimate or home inspection !

Los Angeles Gas Leaks Are Dangerous—Here’s What to Watch For and What to Do

Gas Leaks Are Dangerous—Here’s What to Watch For and What to Do

Gas leaks are one of the most serious hazards a homeowner can face. Even a small leak can pose major risks to your health, your home, and your safety. At Kessler Plumbing & Heating Inc, we provide fast, professional gas leak detection and repair throughout Los Angeles—and knowing the warning signs can make all the difference. Call us day or night for any gas leak concern.

Why Gas Leaks Are So Dangerous

Natural gas is highly flammable. When it leaks into your home or around your property, it can ignite with even a small spark—from a light switch, appliance, or static electricity.

Beyond fire risk, gas leaks can also:

Displace oxygen in enclosed spaces

Cause dizziness, nausea, or headaches

Lead to serious health complications with prolonged exposure

In severe cases, gas leaks can result in explosions or carbon monoxide-related dangers if appliances are affected.

Common Signs of a Gas Leak

Some gas leaks are obvious—but many are not. Here are the key signs to watch for:

1. Rotten Egg Smell

Utility companies add a sulfur-like odor to natural gas to make leaks easier to detect. If you notice a strong “rotten egg” smell, take it seriously.

2. Hissing or Whistling Sounds

A damaged gas line may produce a faint hissing noise near appliances, gas meters, or piping.

3. Dead or Dying Plants

If plants near your gas line suddenly begin to die or discolor, it may be due to a gas leak affecting the soil.

4. Physical Symptoms

Exposure to gas can cause:

Headaches

Dizziness

Fatigue

Nausea

If multiple people in your home feel these symptoms at the same time, it could indicate a leak.

5. Unusual Appliance Behavior

Gas-powered appliances that suddenly stop working properly or burn inefficiently may be a warning sign.

What to Do If You Suspect a Gas Leak

If you think you may have a gas leak, act immediately:

Leave the area right away

Do not turn on lights or use electronics

Avoid open flames or sparks

Shut off the gas supply if it is safe to do so

Call for professional help immediately

Your safety comes first—never try to locate or fix a gas leak on your own.

Gas leaks require specialized equipment and expertise to safely detect and repair. At Kessler Plumbing & Heating Inc, our licensed technicians are trained to:

Why You Should Get a New Water Heater

Thu, 15 Aug 2024 14:53:51 GMT

Hot water is essential for sanitary living and proper health. Modern water heaters are better than ever, which helps ensure a good supply of hot water for your home. Local water heater services can inspect your old water heater and repair or replace it as needed. Here are some good reasons to consider getting a new water heater for your home.

It's at the End of the Service Life

There comes a time in the life of all mechanical things when it's no longer viable to try fixing them. Your water heater is no different. According to Forbes, homeowners should replace their water heaters every 10 years. Local water heater services can inspect your old model and tell you if it still has life in it or if you should replace it with a new and better water heater. The older a water heater gets, the more likely it will fail and leave you without hot water.

The Tank Has Ruptured

Few things are more telling about your water heater than when the tank ruptures. A ruptured water tank is one of the more common ways that internal flooding occurs. Fortunately, homeowners insurance generally covers water damage from a ruptured water heater tank, but it's better to have local water heater services inspect, maintain, and replace your water heater as needed. Proper maintenance and a timely replacement can prevent a ruptured water tank.

Utility Costs Have Skyrocketed

An inefficient water heater can run up your utility costs very quickly. You will likely use more water in hopes of it getting hotter, which raises your water bill. The water heater will also use more electricity, natural gas, or propane to maintain suitably hot water, which also raises your energy costs. Installing a new and more efficient water heater ensures that you get hot water sooner while using less water and energy, which lowers your utility costs.

When you need the help of one of the best local water heater services , you can call Kessler Plumbing & Heating Inc. We install, inspect, and repair water heaters of all types. We can also maintain yours and replace it when its service life is over, so you can continue enjoying the benefits of good hot water. Reach out today!

Upfront Pricing and Written Quotes

3 Benefits of Working With a Local Water Heater Service

Fri, 04 Aug 2023 18:26:17 GMT

Your water heater is one of the most important appliances in your home. Gallons and gallons of water run through the heater every day, and many heaters also store water as well, which can be a major flood risk. According to Bob Vila, a good quality hot water heater can last about 20 years, but when it's time to replace or repair your water heater, you definitely need to call in the professionals. Let's look at the benefits of working with a local water heater service.

Safety

You should be aware that a water heater is a large electrical appliance that pulls a lot of electricity. Because the heater also runs water through it, the combination of water and electricity can create a real injury risk. If you aren't a professional electrician or water heater technician, it's highly recommended that you don't do water heater service yourself. This is definitely not a DIY project. You could get seriously injured if you make a mistake. Call a local water heater service to help with repairs or replacement.

Quality

The water heater in your home is considered a water appliance, and all water appliances pose a flood risk to your home. If the water heater isn't installed properly, water can start to leak. Considering that water heaters are often in out-of-the-way spots in the home, it might be a while before you even realize you have a leak. During that time, your home might experience water damage, or mold may start to grow. Both of these are expensive problems to fix. To avoid these risks, you can call a local water heater service instead. These professionals will be able to assess your issues and make quality repairs you can count on.

Value

If you're concerned about your home's value, you want to make sure that all your major appliances are installed and working properly. This is especially important if you're planning to sell your house soon. Prospective homebuyers want to know that the appliances they are getting were professionally installed and maintained. When you can prove this, you increase your chances of making a quick sale for a good price.

Are you looking for a dependable local water heater service ? If so, Kessler Plumbing & Heating Inc is the name you can trust. Contact us today for a free estimate. We look forward to working with you!

Daily Actions That Will Contribute to Water Heater Longevity

Wed, 28 Dec 2022 18:36:04 GMT

If you have ever tried to live without hot water, you know how important it is to daily life. According to Bob Vila, most people use warm water up to 20 times a day in their homes, which is why it's important to take daily actions that will contribute to the longevity of your water heater. Water heaters have an average lifespan of 8-12 years, according to InspectApedia, but by taking certain steps, you can help extend your unit's life and avoid needing an expensive water heater replacement .

1. Insulate Your Tank

Wrap your water heater's tank in insulation to keep the heat inside and reduce energy costs. This insulation will also create an extra layer of protection against wear and tear that may cause leaks or other problems. Otherwise, keeping the tank in a cool, dry place will help improve its longevity.

2. Set the Temperature Right

Since your water heater will constantly lose heat, it has to cycle regularly to keep the water in the tank warm. You can reduce the rate at which it cycles by reducing the temperature it's set to. According to the Environmental Protection Agency, setting your water heater to 120 degrees Fahrenheit is the best choice since it prevents scalding.

3. Flush Out Sediment Buildup

If you have hard water, sediment buildup can clog your pipes, reduce heating efficiency, and damage your water heater. As part of your regular maintenance, drain a gallon of water from the tank every three months to flush out sediment buildup. This will help keep your unit in top condition.

4. Check for Leaks

Check the water heater and pipes regularly for any signs of leaking. Leaks can cause damage and trigger the need for a water heater replacement, so any signs of moisture should be addressed as soon as possible.

5. Replace Old Parts

Some parts of your water heater may wear out over time and need to be replaced. Check the anode rod, pressure valve, and other parts for any signs of damage or corrosion and replace them if necessary. Replacing these parts will help ensure your water heater is in good condition.

6. Schedule Regular Maintenance

How long has it been since a professional has taken a look at your water heater? Regular maintenance is key to keeping your water heater in top condition. Have a professional inspect your unit regularly to identify any potential problems and ensure that everything is working properly. This will help prevent the need for an early water heater replacement.

Taking these actions will help you get the most out of your water heater. Regulating the temperature, flushing out sediment buildup, and scheduling regular maintenance are all easy steps you can take to ensure that your water heater is in good condition.
