What is a slab leak?
A slab leak by definition is a leak in the piping under the concrete slab within the perimeter of the structure. Leaks under a driveway or under patios can also be referred as a slab leaks.
Determining The Existence Of A Leak
When we first arrive to the job site we must first determine if in fact a slab leak does exist. The first step in water leak detection is to perform a pressure test. This is done by attaching a water pressure gauge to the system. Verify that all faucets and fixtures are in the off position. Any faucets or fixtures that are dripping must be secured by either closing the angle stop or replacing the unit. At this point Blue Planet will determine the water pressure and then close the valve at the main service. If a leak is present there will be a drop in the water pressure. The existence of a hot spot on the floor does not always correspond with the actual location of the leak. Water can travel a long distance before forming a warm area. Locating a leak is a two part procedure. First locating the actual piping and then following along the located piping until the leaking section is found.
Locating The Pipe
The location of the leak cannot be determined until the location of the pipe is determined. Using the transmitter, we wire the transmitter to the piping system close to the area that we are locating. The pipe locator is then used to find the location by picking up the signal that is being transmitted through the pipe. We will mark the location on the floor using an easy clean marker or tape. Than we will trace all the piping in the area that we suspect where the leak is located. When this is accomplished it is time to pinpoint the location of the leak.
Locating The Leak (If you have a leak we will find it)
This is the critical part of the entire process. Using our electronic leak detection equipment we will listen along the marked path of the piping with a microphone to establish a reading. Our technician will than move the microphone along the path of the piping in both directions and then back to the location where the highest reading was present. If there is no difference in the levels then we will use CO2 gas through the piping system which will increase the sound level approximately 10 times. When CO2 is introduced to the system , it should be bled slowly so it does not damage any other piping or fixtures. The purpose is not to pressure the system but merely to create a louder sound vibration for accurate location.
