The plumbing system in your San Clemente, CA home is a network of pipes that starts at the curbside water main and ends at the municipal sewer or your septic system. At any time, any one of these pipes could develop a leak. Knowing how to spot plumbing leaks and pinpoint their locations can save you thousands of dollars in water damage. Timely leak detection can also protect the health and habitability of your living space. Fortunately, there are 10 ways to find plumbing leaks.
What to Know About Your Plumbing System Before Getting Started
Two types of pipes service your San Clemente home: water supply and wastewater. Your home’s main water line feeds all of your potable water supply pipes. Alternatively, all of your wastewater pipes converge into a single sewer line that travels from your home to the municipal sewer main or an underground septic tank. You’ll need to check everything between these two points to find a plumbing leak.
1. Perform a Water Meter Test
Your water meter registers your water use in real-time. Thus, one of the easiest ways to identify a water supply line leak is to turn all taps and plumbing-connected fixtures and appliances off and then check your water meter. If your water meter continues to register water use, there is a freshwater leak somewhere in your home. The leak could be behind your drywall, in a crawlspace, or under your yard.
2. Look Behind and Beneath All of Your Appliance
Sometimes, water leaks are the result of loose appliance connections. Look beneath your dishwasher, washing machine, and all other plumbing-connected appliances.
You should also check all condensate drains for your HVAC system. When heat pumps, condensing furnaces, and air conditioners extract moisture from the indoor air, they route it away from buildings via condensate drains. Over time and lacking sufficient maintenance, these drains can develop thick accumulations of algae and biofilm that inhibit the movement of water. When water can’t drain, it collects in a drain pan until it overflows and creates standing pools of water indoors.
Don’t forget to check your water heater’s storage area, too. Corrosion and buildups of hard water minerals can cause water heaters to leak at their connections.
3. Compare Past and Present Water Bills
According to the U.S. Environmental Protection Agency (EPA), even a single leaky faucet can waste as much as 3,000 gallons of water yearly. If you have a leaky pipe, you can expect to see evidence of the resulting water waste on your water bill. If your water costs have risen significantly within the last two to four months and your household size and appliance use have remained the same, contact a plumber.
4. Inspect Your Landscape
Head outdoors and take a look at your landscape. If your yard is wet and marshy, your main water supply line could have leaks, offset sections, or other problems. Water supply line leaks allow fresh, potable water to escape. However, they also provide points of ingress for bacteria, lawn chemicals, and other dangerous contaminants. When you suspect a water supply line leak, scheduling plumbing service right away is essential. These leaks can seriously degrade your water quality. If left unchecked, they can also damage your home’s foundation.
Alternatively, sudden and excessive growth in outdoor vegetation often indicates sewer line leaks. When underground sewer lines are cracked, offset, crushed, or infringed upon by tree roots or weeds, they leak their contents into the surrounding soils. Both wastewater and solid waste are rich with nutrients that plants, grass, and other vegetation thrive on. The discharge leaking from sewer pipes is also rife with dangerous pathogens. Until the problem is resolved, it’s best to keep everyone out of the yard.
If your plumbing system connects to a private septic tank rather than the municipal sewer main, soggy, sunken areas in your backyard and overgrown greenery can also be signs of septic tank problems. You may have a leaky septic tank or need to have the tank emptied.
5. Listen and Smell
Turn off all your taps and water-connected appliances and walk through your home. Listen for the sounds of running or dripping water. Plumbers often use this technique during professional leak detection. If you hear dripping noises behind your drywall, there’s a good chance you’ve found a leaky water supply pipe.
Pay attention to strange odors as well. Leaking wastewater pipes emit foul sewer gas odors both indoors and out. If you smell scents like rotten cabbage or eggs in or around your home, you may have a ruptured wastewater pipe or a faulty sewer line.
Although leaky freshwater pipes don’t emit sewer gas odors, you may be able to smell wet building materials. If a water supply pipe leaks unnoticed for several days or weeks, you might smell mold or mildew in the affected areas. According to the U.S. Centers for Disease Control (CDC), it takes just 48 hours for mold to form after building materials are saturated.
6. Assess the Quality of Your Tap Water
If your tap water is cloudy, discolored, foul-tasting, or smelly, there’s a good chance your water supply line is compromised. You might have a damaged main water line or a nearby water supply pipe.
7. Look for Wet Drywall, Flooring, and Baseboards
Check for wet drywall, flooring, and baseboards, especially in areas with active dripping sounds, sewer gas odors, or mold and wet building materials. You may even find soft and yielding drywall areas, along with warped floorboards and sub-flooring.
8. Check Your Slab
Inspect the floor on the lowest level of your home. If you have a slab leak due to a damaged wastewater or water supply pipe, the flooring could be damp, discolored, or warped. You can also listen for the sound of running water in this area, check for changes in humidity, and sniff the air for sewer gas or mold odors.
9. Schedule a Whole-House Plumbing Inspection
Whole-house plumbing inspections are comprehensive plumbing inspections that look for:
- Slow and hidden leaks
- Damaged pipes
- Fluctuating water pressure
- Accurate fixture installation
- Backflow issues
You should schedule a whole-house plumbing inspection every one to two years. If you haven’t had one in a while, this is the perfect way to ensure that all of your wastewater and water supply pipes are working as they should.
10. Schedule Professional Leak Detection
If you’re up to date with whole-house plumbing inspections and suspect a water leak, you need professional leak detection. Leak detection services take an all-encompassing approach to locating wastewater and water supply pipe leaks. Plumbers have multiple options in leak detection equipment and techniques at their disposal, including:
- Acoustic devices
- Thermal imaging
- Video camera inspections
These and other professional leak detection methods allow plumbers to find leaks without cutting into drywall, tearing up flooring, or disrupting your lawn and landscaping.
