Why find leaks fast
Water soaks wood and drywall. It makes mold and rot. It can damage floors and cabinets. Water near wires can be dangerous. A small drip can make a big bill. Find leaks now and stop the harm.
Signs of a hidden leak: what to watch for
- A high water bill with no change in use.
- The water meter runs when all taps are off.
- A constant sound of water when no one uses it.
- Wet or dark spots on ceilings or walls.
- Paint that peels or bubbles.
- Warped or soft floor boards.
- Mold, mildew, or a musty smell.
- Puddles near walls or under sinks.
If you see any sign, act fast. Take photos for your records.
Simple checks you can do now
- Look at the water meter. Turn off all taps and appliances. Watch the meter for five minutes. If it moves, water is running somewhere.
- Check your bill. A sudden jump can mean a slow leak.
- Feel baseboards and floors. Soft or warm spots can hide water.
- Smell for mold. A musty smell means moisture is present.
- Open cabinets and check under sinks. Look for wet pipes or stains.
- Check behind the washer and fridge. Hoses can split or loosen.
- Test the toilet with dye. Put a few drops of food dye in the tank. Wait 10 minutes. If color appears in the bowl, the flapper leaks.
Use simple tools for better checks
- Flashlight to see behind pipes and in dark spots.
- Bucket and towels to catch small drips.
- Wrench to tighten a loose fitting if you know how.
- Food dye for toilet tests.
- Moisture meter to read wetness in walls and floors.
- Camera or phone to take photos for your records.
If you have a meter or sensor app that links to a smart meter, use it to watch night flow and leaks.
When to look outside too
Check the yard and roof. Look for low spots or soggy ground near the house. Check irrigation lines and hose bibs for slow leaks. Look up at roof lines for stains on soffits and eaves. Tree roots can crack sewer lines. A wet patch in the yard that keeps coming back can mean a buried leak.
Hidden leaks in appliances and systems
Water heaters, dishwashers, washing machines, and ice makers can leak slowly. Check hoses for cracks and clamps for tight fit. A leaking water heater may leave rust or puddles at the base. If your water heater is old, plan to replace it before it fails.
What NOT to do: safety first
Do not touch electrical outlets or panels near wet areas. Turn off power if water is near wiring and you can do so safely. Do not use chemical drain cleaners in an active leak. Do not break walls or floors without a plan. If you smell gas near a water heater, get out and call the gas company and a plumber.
When to call a professional plumber
Call Delta Blue Plumbing if:
- The meter moves with all water off.
- You see large wet spots or active leaks.
- You smell sewage or gas.
- You find mold growing on walls or ceilings.
- You cannot find the source or stop the leak.
A pro uses tools like video sewer cameras, infrared cameras, and pressure tests to find the leak fast and without guesswork.
