Connections & Networks

Connection points are key elements of the drinking water network.

On the user’s side, these connections link the branch line to the metering environment.

On the mains side, they allow extension or repair of the network.

Great care must be taken when choosing and installing these connectors, which form an integral part of the water mains infrastructure, in order to avoid water leaks.

Make the right choice to

Ensure the connections are watertight

Installing quality, easy-to-use products helps the installations and the entire drinking water network to last longer.  

The tightness of a connector is fundamentally important in assuring a durable bond between the different pipes and threads. The use of a technology which has already been tested on other product ranges offers greater confidence that the assembly will be reliable.  

Connection fittings have to respond to a wide range of configurations, dimensions and compactness, and must also adapt to the existing pipework. A complete, simple and modular product range not only speeds up the installation process but also allows pipe fitters to connect to all types of branch line and select a straight fitting, elbow or tee, depending on the ground conditions.

About pipe connectors

Pipe connectors join up the pipes while assuring a watertight seal between the different conduits and pipe threads. They can be found on the subscriber side and also on the mains side, in the water supply network.  

Raccordement PVC

Sainte-Lizaigne’s stainless steel sleeves are reliable and easy to install. With an embossed seam, they give a perfect seal even on a damaged pipe, and have an ergonomic grip for easy installation. Various lengths are available to allow for adaptation to the damage on the conduit. The double-shell version is easy to install on large pipe diameters and allows for better distribution of stress across the joint, for guaranteed watertightness.  

The suction box is an innovative solution for the urban environment. It can be used for different purposes at the same point: bleeding air from the line, cleaning pavements, introducing disinfectant but also for temporary water supply on-site. It also comprises a pollution control device and protects against backflow. Designed for easy installation and maintenance, suction boxes can be used together and serviced via the multi-purpose cap.
