A leaking pipe underneath a sink.

A water leak in your home or office is a serious problem because it increases your water bill without you knowing there is a hidden leak somewhere. You won’t necessarily know you have a leak until you get your water bill and see the usage increase, yet you know you haven’t used more water than in the previous months. To solve the problem, you’ll need a professional plumber specializing in water leak detection. The water leak can lead to the causing of other issues, such as:

  • Toxic mold
  • Structural damage
  • Electrical problems
  • Flooding
  • Plumbing failure

The sooner the leak is located, the quicker the repairs can begin and save you from further costs and problems.

What are the signs of possible leaks?

Plumbers look for signs of water leaks in a variety of ways. One of the most obvious is a visible water spot that looks like a stain on a wall or ceiling. 

  • Mold or mildew spots, along with musty odors
  • Peeling paint or wallpaper on the drywall or wood 
  • Running water sounds when nothing is in use
  • Dripping faucets in sinks or outside on the hose bib
  • Sagging ceilings are very serious and could mean the leak has been there for a while
  • Damaged flooring that is warping slowly due to a leak
  • Reduced water pressure

Another method to detect a water leak is to check your water meter when no one is home. When you leave home, write down the meter reading and inspect the number when you return. If the meter number has moved at all, you likely have a water leak. Let a plumber know these changes in meter readings to determine how big of a leak it is.

Where do plumbers usually look for leaks?

After carefully inspecting the home or office for suspected leaks, the plumber will narrow their focus to fixtures. These “endpoints” can be toilets, faucets, irrigation systems, valves, or the outdoor pool. The leak could come from the fitting or adaptors connecting pipes and joints. Once the problem area is located, the plumber can perform further tests to pinpoint the leak.

Tip: A simple way to detect a pool leak is to do a bucket test. Simply place a bucket on the step of your pool with equal water levels inside and outside the bucket. Mark the water level. Wait 24-48 hours and see if the water level changes inside or outside the mark. If the water level shows less on the outside, it could mean you have a pool leak. If the levels remain the same but are only slightly lower, it means normal evaporation in the air. A qualified plumber can use further detection methods to find the cause of a pool leak by checking the pump to the lines without digging up the deck.

What do plumbers use to find leaks?

Plumbers have various tools they use to detect water leaks. Using modern methods, they can go underground or between walls without disrupting your home or office structure. Some of those methods include:

  • Thermal imaging uses a handheld device to scan for temperature changes in pipes. The temperature doesn’t have to be hot to be detected because thermal imaging can detect even the smallest changes in liquid temperature.
  • Acoustic detection requires the plumber to use headphones and a microphone to detect the sound of running water. All leaks produce sound frequencies, with some not being openly audible, which is why a plumber can listen for abnormal noises in the pipes.
  • Video plumbing technology efficiently checks buried pipes by using a tiny video camera attached to a flexible fiber optic cable inserted inside pipes. The plumber can watch on a screen from above ground and detect where the leak is. 

Tip: A preventive utility tool you can install is a mechanical water leak detection system to measure your home’s water flow. It’s a helpful tool that can shut off the water at its source during freezes or suspected sustained leaks. Monitoring water usage can give you peace of mind, especially when you are away from home, and prevent catastrophic frozen water damage during a winter weather event.

What tools does a plumber need to do a good plumbing job?

In addition to high-tech equipment used to find leaks, a plumber will need specialized tools designed specifically for fixing plumbing problems. A plumber uses pipe wrenches, flaring pliers, pipe vises, pipe cutters, pipe bending machines, thread sealing tape, crimp tools, and many more. You want to leave the repair to a professional who knows what each of these tools is used for rather than you trying to fix a water leak yourself. Leave it to the professionals to get the job done.
