One of the most common questions we are asked on a slab leak in Phoenix before we even go out to the appointment is how we are going to find the leak. To put it differently, how are we going to find the leak? We understand how important your home is to you, we know how much panic the two little word “slab leak” can cause you and that you would want to make absolutely sure that the leak can be found before any demolition work is performed in your house. In this article we will discuss the most common used slab leak detection methods and how they will pinpoint where a leak is located underneath your property.
Acoustic Leak Detection
When a leak is located underground, it gives off a certain sound. There are a lot of different factors that contribute to this sound such as:
- The water pressure
- The material the pipe is made of
- The size of the pipe
- The surface cover of the pipe
- The soil compaction and type of soil covering the pipe
The most important factor is the water pressure and this is what most Leak Locators focus on to detect the leak. Where the sound is the loudest is normally where the leak is located.
It is very important for the Leak Locator to know the material the waterline is made of and the diameter size of the line, otherwise it can result in the Leak Locator pinpointing the leak at the wrong location. This could lead in either sealing off the wrong line or demolition work done in the wrong spot.
Now before the Leak Locator can actually listen to find the leak, the waterline should be marked off by using a waterline transmitter. Once this is done the Leak Locator will be able to listen to the line in order to determine where the most noise on the line is coming from. Once the break in the line is pin-pointed, the Leak Locator will test if it is the correct line that is leaking.
A simple method that most Leak Locators use is by connecting a pressure gage to the hose bib connected to the main shut-off valve of the house. Once the pressure gage is connected, the main-shut off valve is closed. If the pressure on the pressure gage starts to drop, it means that somewhere inside the house there is a leak. If the pressure on the gage remains the same for about 30 minutes with the main shut-off valve still turned off, most likely it means there is no leak in the plumbing lines.
This method is not very effective mainly because it only indicates if you have a leak or not, and not where exactly the leak is located.
Thermal imaging and infrared cameras are probably the most commonly used equipment used for slab leaks in Phoenix, specifically on hot water lines. By using thermal imaging, a lot of destructive probing methods are disregarded. The thermal imaging camera will pick up “hot spots” underneath the slab and normally where the hottest spot is located is where your leak is located.
This method however is only good if you have a water leak running from your water heater and cannot be used on a leak on any of the cold water lines.
The only issue considered with thermal imaging is allowing the energy transfer enough time to transfer through the flooring to the surface which takes time.
