If your house does not have a damp-proof membrane, you might notice the seepage of water under the ground floor slab, especially during the rainy season. In other instances, the sewer pipes might be perforated, causing them to leak. In the unfortunate situation that the plumbing pipes under the floor slab have begun to age, you should call a plumber immediately to resolve the issue. Since the dampness can cause a myriad of health problems, a leakage under your floor slab is not something to take lightly.
While diagnosing the problem, the plumber might encounter some difficulties when attempting to reach the faulty pipes. In most cases, the foundation will begin to sink, meaning that the plumber will be forced to hack it in the quest to find the faulty pipe. The aged copper pipes pose some risks since they wear out as a result of corrosion. After hacking the slab and replacing the faulty pipe, the plumber will install the foundation properly. Where possible, the plumber will transfer the pipework to an area where it does not pose such risks. While repairing the foundation, you will have to replace the damp-proof membrane to avoid such problems in the future.
Sewer leak repair
If you notice a foul smell coming from underneath your foundation, the chances are that you have a sewer leak. Since the sewer carries human waste, you should call a plumber immediately to deal with the emergency. Sewer leaks can expose your family to several health risks, meaning that you need to act as quickly as possible. In some situations, the sewerage might mix with your domestic water in the supply system. When repairing the sewer, you need to inspect the domestic water supply system to ensure that you are safe. Remember that the pipes are likely to break when the foundation is lifted. A severe sewer leakage might render your home uninhabitable during the repair process.
Repairing the plumbing system in an old home
Once the repair work is done, the plumber will run some tests to ensure that all leaks have been corrected. In most cases, the plumber will recommend a complete overhaul of the pipework. By replacing the copper pipes with the modern UPVC pipes, you can prevent a recurrence of the problem in the future. It is also necessary that you use sand when burying the pipes. Sand allows the pipes to expand and contract easily without posing any problems. Clay tends to cling to the pipes, making such movements impossible. Avoid incurring the cost of repairing the rusty galvanized pipes and replace them with UPVC. While you will spend a fortune on the replacement, you will realize that UPVC pipes are cost-effective since they can prevent the water leak under my foundation. Copper reacts with the concrete, aggravating the problem significantly.
The galvanized pipes tend to collect some mineral deposits that can cause pressure to build up in the pipes. Fortunately, you can prevent the problem before it becomes a nightmare. If you realize that your taps are producing dirty water, call a plumber immediately.
