Advantages of multilayer pipes for new installations
Multilayer pipes are the ideal solution for water distribution networks in new buildings. Their aluminum structure surrounded by layers of polyethylene gives them excellent mechanical strength, while remaining extremely flexible. These technical features mean they can be laid quickly and cleanly, with significant advantages:
- Enhanced durability (corrosion and scale resistance)
- Optimum flexibility (reduced number of connections)
- Easy installation (no welding required)
- Perfect compatibility with heating and domestic hot water systems
Site preparation and choice of materials
Before any installation, a careful study of the distribution plan is essential. Determine precisely :
- The optimum layout to minimize pipe lengths
- Passage points through partitions and slabs
- Location of shut-off valves and access fittings
Choose certified pipes (NF standard or European equivalent) and select the right diameter for each application:
- 16 mm for individual feeders
- 20 mm for risers
- 26 mm for main connections
Professional installation techniques
1. Pipe cutting and preparation
Use special cutting pliers to obtain perfectly clean ends. Carefully deburr each cut and insert the crimping ring before assembling the fittings.
2. Pipe fastening and protection
- Secure pipes every 60 cm or less with suitable clamps
- Provide protective sleeves at wall penetrations
- Keep a minimum distance of 3 cm from electrical circuits.
3. Connection and pressurization
- Always use quality press fittings
- Check every connection before commissioning
- Perform a leak test at 1.5 times normal pressure
Tips for a long-lasting installation
To guarantee the longevity of your system:
- Thermally insulate pipes in cold zones
- Balance circuits for even flow
- Clearly mark pipes (hot/cold water)
- Protect floor passages mechanically
