How Do Plumbers Find Water Leaks In Walls

How Do Plumbers Find Water Leaks In Walls?

 No two leaks in the property are the same. And inevitable leaks are noticeable (for example, a leaking pipe may be impossible to miss as the water gushes out), some are not-and several can go undetected for lengthy periods. 

Not only can hidden water leakage in walls do significant harm to your house over time, but they can even add up your water bill and cost you a lot of money. 

Leaks may also impact construction products and contribute to the production of mildew and mould.

You can be shocked to learn that several breaches remain undetected since they exist in areas that are out of reach. 

If you don’t check the water bill daily or have a specialist check the home for water leakage, you could spend hundreds of dollars a year on leakage.

 The smallest pinhole leak will ruin the whole drywall and lead to several other problems, which is why it is crucial to keep up with any leaks in your house.

Below, we look at how plumbers identify water leakage in walls and what equipment and methods they use. 

For plumbing leaks, it is critical to employ a skilled and knowledgeable plumber who has the right equipment to find leaks. 

Plumpers have leak monitoring systems that can quickly and reliably identify the cause of the leak.

Video inspection device

For the most convincing identification of leaks, plumbers use camera pipe inspection devices. 

There are compact cameras that are installed on long, lightweight fiber optic cables. 

Plumpers may install these in the faucets and other plumbing outlets to prevent leakage attached to walls. 

The camera relays the photos back to the display where the plumber can see the internal state of the pipe. 

This helps them to find the cause of leaks in walls that could be impossible to find from the outside and to provide them with any extra details they need to fix the leak.

Listening to the disks

Listening disks and field microphones are some of the most common instruments that can be used for plumbers to track and identify water leakage. 

Listening disks are items of equipment that enable plumbers to detect leakage in dry walls. 

Using acoustic technologies, listening disks intensify the acoustic of water leaking back into the headphones when positioned on the wall. 

A professional plumber would be able to listen to the rhythm of flowing water below as he passes along the pipes. This offers the plumber a clear understanding of where the leak is when seeking to access it. 

The Soil probe

Leaks that arise in the drainage line and the critical waste may be quite troublesome. 

This kinds of leaks also pass across lawns and yards. The soil probe helps plumbers to respond to normal pressure or pressurized leakage across grass and rock walls. 

When the machine moves closer to the leaks, the sound is becoming more apparent, and this enables plumbers to figure out where the leak is. 

Experienced and professional plumbers may be able to discriminate between the various signals they detect to determine the form of leaking, how big it is, and the correct approach to reach it and patch it.

Thermal Imaging Camera

Thermal imaging cameras or heat sensors may be used to help locate secret leaks in hot water pipes beneath floorboards, pavement, and behind walls. 

Thermographic cameras may also find trouble areas where the human eye can not spot, exposing secret water leaks that are often out of reach.

Thermography is the concept used to define infrared imaging and measuring cameras to see and quantify thermal energy released from the material. 

Thermal imagery may be used to track moisture in ceilings, flat roofs, and behind walls. 

Using thermal imaging cameras is an excellent way to quickly look at expansive environments which does limited interruption with no harm to the house. 


In conclusion, until any advanced machinery is required, the plumber can take a stroll through the house and look for any indicators of potential leaks in the walls. 

And this may involve testing the appliances, searching under all the sinks in your home, and examining the irrigation and pool systems. 

Usually, the water meter would often be tested to provide the plumber with an indication of how much water is being used.
