Plumbing leaks can cause significant water damage, increase your water bill, and contribute to mold growth if left unchecked. At DireX Handyman Pros, we recommend regularly checking for plumbing leaks to prevent costly repairs and ensure your plumbing system is functioning properly. In this blog post, we’ll walk you through when and how to check for plumbing leaks so you can stay ahead of potential issues.
When Should You Check for Plumbing Leaks?
Plumbing leaks can happen at any time, but there are certain situations when checking your plumbing system is especially important:
When You Notice an Increase in Your Water Bill
A sudden spike in your water bill may indicate a hidden plumbing leak. If you’re using more water than usual but haven’t changed your water usage habits, it's time to check for leaks.
When You Hear Running Water
If you hear the sound of running water when no faucets are turned on, this could be a sign of a hidden leak somewhere in your system. It’s important to locate the source to prevent wasting water.
If You See Water Damage or Damp Spots
Water stains or damp spots on walls, ceilings, or floors are obvious indicators of leaks. If you spot these signs, check the surrounding pipes to find the source of the leak.
Before or After Winter
Frozen pipes are a common issue during winter. Check your plumbing system in the fall before the cold weather sets in, and inspect again in the spring to ensure that pipes didn’t freeze and crack over the winter.
Routine Maintenance
Even if you don’t notice any immediate issues, it’s a good idea to check for plumbing leaks during routine home maintenance, at least once a year, to catch problems before they escalate.
How to Check for Plumbing Leaks: A Step-by-Step Guide
Step 1: Check Your Water Meter
Locate your water meter: The water meter is typically found near the street or in a basement, crawl space, or utility room. Make sure you know where it is and how to access it.
Turn off all water fixtures: To get an accurate reading, make sure all faucets, showers, toilets, and appliances using water are turned off.
Record the meter reading: Take a note of the current water meter reading.
Wait for 30 minutes to an hour: Avoid using any water during this time.
Check the meter again: After the waiting period, check the water meter again. If the reading has changed, it could mean you have a leak somewhere in your plumbing system.
Step 2: Inspect Visible Pipes for Leaks
Look for wet spots: Examine visible pipes under sinks, in the basement, and around your water heater for any wet spots, puddles, or signs of moisture.
Check joints and connections: Pay special attention to the joints and connections of pipes, as these are the most common places for leaks to occur.
Look for corrosion: Corroded or rusted pipes are more likely to develop leaks. If you notice any signs of corrosion, it may be time to replace the pipes.
Step 3: Check Toilets for Silent Leaks
Food coloring test: A simple way to check for leaks in toilets is by placing a few drops of food coloring into the toilet tank. Wait about 30 minutes without flushing. If the water in the toilet bowl changes color, you have a slow leak in the tank.
Check the flapper valve: The most common cause of a leaking toilet is a worn-out flapper valve. If it doesn’t seal properly, water will leak continuously into the bowl, leading to high water bills.
Step 4: Check Under Sinks and Around Appliances
Examine plumbing under sinks: Open the cabinet under sinks and check for any dampness, drips, or puddles around the pipes.
Look for leaks around appliances: Inspect washing machines, dishwashers, and water heaters for any signs of leaks or water damage around the hoses, valves, or connections.
Step 5: Check for Water Damage
Inspect your walls and ceilings: Look for water stains or discoloration, especially around pipe runs and behind appliances. If you see water spots, it could be a sign that water is leaking inside the walls or ceiling.
Check floors for softness: Soft or swollen spots on floors may indicate a water leak beneath the surface. This is often a sign of a hidden plumbing leak.
Step 6: Use a Leak Detection Tool (Optional)
Acoustic leak detectors: If you suspect a hidden leak inside your walls or underground, consider using an acoustic leak detector. These devices listen for the sound of water flowing through pipes to help pinpoint the leak’s location.
Thermal imaging cameras: These cameras detect temperature differences in walls and floors caused by water leakage. A professional plumber can use this tool to identify hidden leaks in your home.
What to Do If You Find a Leak
If you find a leak during your inspection, here’s what you should do next:
Turn Off the Water Supply: If you locate a leak in a specific area, shut off the water supply to prevent further damage. You can do this by turning off the main water valve or the shutoff valve near the leak.
Call a Professional Plumber: Small leaks can often be fixed with DIY methods, but larger or more complex leaks require professional assistance. If you’re unsure of how to fix the problem or if the leak is hidden, it’s best to contact a professional plumber.
Take Immediate Action to Minimize Damage: While waiting for professional help, use towels, buckets, or containers to catch any water that may leak out. Move furniture or valuables out of the affected area to prevent water damage.
