A well-designed water distribution system guarantees stable pressure, uniform supply to water points and optimized consumption. Whether for a single-family home or a multi-family building, it’s essential to respect certain rules to avoid pressure drops, flow variations and hygiene problems.

1. Define requirements and distribution plan

Before installing the network, it’s important to determine the water requirements and the most suitable type of installation. Each water point (tap, shower, WC, washing machine) must be supplied with a sufficient flow rate, while avoiding over-consumption.

There are two types of distribution:

• Octopus network: each water point is directly connected to the main manifold, ensuring uniform pressure and limiting losses.
• Branch network: devices are supplied in series from a main pipe, which is simpler to install but can lead to pressure variations.

2. Choosing the right materials

The choice of pipes is essential to ensure the durability and efficiency of the network.

• Copper is reliable and resistant, but requires a more technical installation with soldering.
• PER is flexible and easy to install, ideal for flush-mount installations.
• Multilayer combines the strength of metal and the ease of installation of PER, with better resistance to temperature variations.
• PVC is used for drains and is not suitable for pressurized drinking water.

3. Install manifolds and shut-off valves

A well-positioned manifold distributes water evenly throughout the system. Each circuit should be fitted with a shut-off valve, facilitating maintenance and repairs without cutting off the entire supply. We recommend installing a pressure reducer if inlet pressure exceeds 4 bar, to protect pipes and equipment.

4. Insulate and secure pipes

Pipes must be properly secured to avoid vibrations and rattling noises (water hammer effect). Thermal and sound insulation is also essential, notably to limit heat loss from hot water circuits and reduce noise pollution in walls.

5. Check installation before commissioning

Before using the system, a leak test is essential. This involves filling the system with water and checking that there are no leaks from fittings or joints. Gradual pressurization allows any faults to be identified before final commissioning.
