How To Repair A Slab Leak
A slab leak is an industry term used to define an instance in which there is a leak in one of the many water lines that run below the concrete floor of a home. There are several causes to this phenomenon, most commonly as a result of a reaction between drinking water and the copper pipes. Sometimes they can also be caused by poor installation practices, contact with concrete, non-reamed pipes or too much soldering flux but this is seldom the case.
The first step in repairing a leak is locating the source of the leak. This is requires a thorough process and technical expertise. Breaking into a slab without positive evidence of an actual leak is not recommended. Water leaks in the slab have many symptoms including: The sound of running water when all water on the property is turned off, a hot spot on the floor which could indicate a hot water leak, cracks along the walls or in the flooring, excessive moisture causing the formation of mildew and last but not least – higher than expected water bills.
There are a variety of modern tools that can be used to detect leaks in a non-destructive, cost effective manner. Electronic amplification equipment and electromagnetic pipeline locators are two examples of the tools available. With the use of modern tools and equipment your leak can be located and repaired in the least destructive manner possible.
Once you have located a slab leak on your property there are several different ways in which you can choose to repair it. For newly and more recently constructed properties, a spot repair in which you open up the slab at the spot of the leak and repair the leaking pipe will offer you the most cost effective solution. In older properties with older plumbing systems that may have a history of leakage, a “re-pipe” or rerouting of the line that is leaking will be the most effective option. If your system has a series of small leaks that would render the normal cost of repair too high, you can consider a pipe coating. An in-place epoxy pipe coating is applied through the inside of the plumbing when the cost is too high or it is too inconvenient to dig up the slab itself. Generally speaking the process of repairing a leak will involve a two to three day process beginning with detecting a leak, locating the source of the leak and then repairing the leak. If you do not possess the correct tools or technical skills in order to properly repair the leak(s) yourself it is highly suggested that you seek professional assistance. Remember that when seeking outside professional assistance that it is always wise to research your local market. Compare services, prices and customer reviews in order to make the right choice for your situation.
