What are Leaks and Leak Testing? | Slab Leak Repair in Arlington, TX

What is a Leak?

A leak is a flow of liquid through the wall of a vessel or even a pipe due to a hole, crack, or an imperfection of some kind. It can allow for some serious loss of matter. Leaks basically require a pressure difference to generate the flow. They always flow from higher pressure to lower pressure areas much like the concept of basic convectional currents. Any fluid material will always move from high pressure density to low pressure density areas. This leak can therefore cause some serious damage in the case of water as it would seep through and therefore create a slab leak repair in Arlington, TX threat.

Leaks are pictured as going from excess positive pressure in the pipe to outside which would be atmospheric pressure which is much lower than the artificial pressure created by the water inertia inside the pipe. This is not always the case (a leak could be from atmosphere to inside an evacuated object but that would be for submersed objects or in some cases even for thin air containment), but it helps to think about it this way mostly because of the units and terminology being based on this model which is rather easier to manage then. Plus, it can enable us to better help you in the case the slab leak repair in Arlington, TX is very little or at an early stage which is easy to contain. On the other hand, if the slab leak in Arlington, TX is intense, then there is no point on working on it without releasing the pressure of the water in the pipe.

Leak Testing – What are the First Few Questions We Ask Ourselves?

Key questions at the start of any leak test requirement are:

  • What are the precise measurements of the component in question and what are its internal volume capacity and threshold?
  • What is the leak limit and how can we keep the material from leaking alternatively?
  • Is it a simple design which would not have hidden components and other such cuts or designs on the inside of the model which would affect the integrity of the pressure containment of the pipe?
  • Are the parts clean and dry? Are they fully prepared to be tested and are fully only what the base component is and nothing more?
  • Is there access to inside or is it a sealed unit? And in either case how much is the total capacity and tensile threshold of the material and design?
  • Is it rigid or flexible?
  • Are parts at ambient temperature?
  • What is the surface finish of any sealing surfaces?

Leak Testing – Generic Systems


This test piece and the reference volume are simultaneously pressurized (or evacuated) to a preset pressure which would be used to determine the thresholds. The air in the system is then allowed to stabilize which would mean there is ample time given so the air inside can normalize pressure-wise. All this has to be done with the supply valves all closed therefore ensuring vacuum. Then the Differential Pressure Transducer is automatically zeroed which would mean the inducer and pressure measurements are made here.

After this stabilization time, the pressure is changed and then recorded in the test piece after which it is compared to the pressure change in the reference volume. This is usually done with the help of a Transducer. If the test piece is leaking, the difference will increase and be measured; an alarm limit may be set for a pass/fail decision.

Pipe Pressure Systems

A vacuum pump is used to evacuate the pipe chamber and test piece simultaneously to a preset the vacuum. This is a means used to test the integrity and consistency of the pipe to ensure these are proper and would not cause some kind of slab leak in Arlington, TX.

At this preset level, the pipe chamber would be isolated and the chamber would be evacuated further to a very low pressure allowing for it to be tested in low and high pressures and preemptively reduce the chances for a slab leak in Arlington, TX. This is done because positive and negative pressure can both damage the pipe and despite there being lesser cases of the latter it is a serious concern at least in the case of a slab leak in Arlington, TX the first one is more important. A positive pressure variation is therefore created between the test piece and the chamber then the piping tested for leaks.

The same is done the second time to ensure that the pipe is able to sustain negative pressures and still function as intended. This is a means that can be used to reduce the pressure that is released into the pipe and therefore could be a potential cause for damage incurred to the pipe.


A Mass Spectrometer analyses a sample from the pipe as the vacuum continues to be drawn this would show where the pressure is most applied also disclosing weaknesses in the piping or cracks and slits. The Mass Spectrometer measures the water leakage and potential to cause a slab leak in Arlington, TX later on and sets the pass/fail decision.

The pressure is often compared to the chamber pressure before testing to ensure that the pressure applied from outside as well as inside would not affect the integrity of the pipe. This is done to avoid saturating the Mass Spectrometer in the event of a gross leak. Furthermore, the means used to check upon the leak can be altered as you can even submerse the material and test it under a variety of pressure situations for all kinds of slab leaks in Arlington, TX.


The idea is to test either the pipe or something of a similar structure to prepare you for when it might give away or break. This would enable you to predict and prepare for a slab leak. Once witnessing the leak starting or springing you should call us, your Slab Leak repair in Arlington, TX specialists and have them take a look at what the matter is or how you should approach it and whether or not it needs a Slab Leak repair in Arlington, TX team right now or not. As a matter of fact, if you feel your house might need a check up or two please click here and book yourself a consultation which would enable you to better understand when the inevitable will happen and how you can prevent it from aggravating into a serious slab leak situation.
