The most common causes of plumbing leaks are pipe corrosion, high water pressure, issues in joints and fittings, and freezing temperatures. You can check the water meter, inspect the plumbs visually, or use a leak detector to find all the leaks.

But there is more!

This complete guide will show you all the 10 most common methods of plumber leak detection. Read till the end and make an informed decision regardless of the matter.

What Causes Plumbing Leaks?

You may have a plumbing leak in the ceiling or the walls of your home because:

  • pipe corrosion;
  • high water pressure;
  • pipe joints and fittings;
  • freezing temperatures;
  • wear and tear; or
  • water quality.

Some of these culprits are difficult to avoid, so if you eventually face a plumbing leak at your home, know that is not entirely your fault. But don't forget that home plumbing maintenance is always welcome!

How To Detect Water Leaks In Home?

The most common plumbing leak tests are checking for the water meter, monitoring the water usage, visually inspecting for signs, testing the toilets, listening for leaks, using a detector, performing a pressure test, checking outdoor spigots, inspecting the heater, and calling professional service.

Learn the details of each method by reading the list below.

  1. Check Your Water Meter: Turn off all water sources in your home, locate your water meter, and check the leak indicator. If it is moving, there is probably a leak.
  2. Monitor Water Usage: Keep an eye on your water bill for any unexpected increases in water usage, which could indicate a leak.
  3. Make A Visual Inspection: Inspect visible pipes, faucets, and fixtures for any signs of leaks, such as water stains, puddles, or corrosion. Check under sinks, around toilets, and near appliances that use water.
  4. Dye Test For Toilets: Add a few drops of food coloring into the toilet tank. Wait for about 15-20 minutes without flushing. If color appears in the bowl, there is a leak in the toilet tank – which is a common plumbing issue in modern houses.
  5. Listen To The Leaks: In a quiet environment, listen for the sound of running water, which could indicate a hidden leak.
  6. Use A Water Leak Detector: Install water leak detectors in areas prone to leaks, such as near water heaters, washing machines, and under sinks. These devices can sound an alarm when they detect water.
  7. Pressure Test: Turn off all water-using appliances and faucets. Record the water meter reading. Wait for a few hours without using any water. Check the meter again. If the reading has changed, there might be a leak.
  8. Check Outdoor Spigots: Ensure that outdoor spigots are turned off completely and not dripping.
  9. Inspect the Water Heater: Look for any signs of leaks around the water heater. A leaking pressure relief valve or corroded tank could be an issue.
  10. Call Professional Leak Detection Services: If you suspect a hidden or underground plumbing leak, hire a professional leak detection service that uses specialized equipment like acoustic sensors or infrared technology. They know all the secrets of plumbing.

Can I Use Plumber's Tape To Fix Water Leaks?

Plumber's tape is a classic DIY temporary solution for small leaks. It is used to seal the leak, but not to fix damaged threads or other plumbing issues. Once you know that, you can use it, for sure – just always keep it in mind..!

How Much Plumber's Tape To Use?

For standard pipe threads, a few wraps are usually enough, while larger threads may require more wraps. Smaller threads, like those on faucets, need only a few wraps to seal. High-pressure connections, such as gas lines, should use an adequate amount of tape for a secure seal. 

How Much Does It Cost To Detect A Leak?

The average cost of hiring a professional plumber to find plumbing leaks ranges from $ 150 to $ 500. Prices vary according to the complexity of the issue, the location of the leaks, and the methods employed for detection.

But safety over money here! Plumbing leaks can develop into serious water damage. If you do not want that to happen in your house, call Wisercosts' plumbers. They will detect and fix any threatening leaks you might have.
