How to check the underfloor heating piping for leaks?
Checking the underfloor heating piping for leaks is an important measure that helps ensure the efficiency of the system and prevent potential damage. In this article, we go through how to check the underfloor heating pipeline for leaks step by step.
1. Preparations
Before starting the inspection, make sure you have all the necessary tools and supplies. These can be, for example:
- Pressure gauge
- Water pump
- Leak detector
- Soap solution
- Flashlight
2. Checking the system pressure
The first step is to check the system pressure. This can be done as follows:
- Close all valves leading to the underfloor heating piping.
- Connect the pressure gauge to the system and check the pressure. Normally, the pressure should be around 1-2 bars.
- If the pressure is too low, add water to the system using the water pump until the pressure is at the right level.
3. Locating leaks
Next, it’s time to locate any leaks. This can be done in several different ways:
- Visual inspection: Inspect all visible piping and connections using a flashlight. Look for signs of moisture, rust or water stains.
- Soap solution: Mix the soap solution and apply it to the pipe joints. If bubbles rise from the joints, it is a sign of a leak.
- Leak detector: Use a leak detector that can detect even small leaks in the pipeline. This device is especially useful if the leak is hidden under the floor.
4. Corrective Actions
If you find a leak, it’s important to take corrective action as soon as possible. Here are some common repair methods:
- Sealing: Small leaks can often be repaired by resealing the joints.
- Pipe replacement: If the pipe is damaged, it may be necessary to replace it completely.
- Calling a professional: If you are not sure how to fix a leak, it is always a good idea to call a professional.
5. System retest
Once repairs have been made, it is important to retest the system to ensure that the leak has been repaired. Repeat the pressure check and leak detection to make sure everything is in order.
Checking the underfloor heating piping for leaks is an important part of system maintenance. A regular check helps ensure that the system is working efficiently and prevents potential damage. If you need more information or help, you can consult the following sources:
