There are many different types of materials that have been used in the installation of water mains from Asbestos cement, PVC, Medium Density Polyethylene (MDPE), Copper, Galvanised Iron to the more common Ductile and Cast Iron. With this there are many fittings to adapt and maintain these different materials for use in repairs to water mains, new connections for supplies to properties and general preservation, see demonstrations below:

• Mains / supply pipe diversions: Most properties will still be fed by the original supply pipe installed when the properties were built. This can be a problem if that property is to be extended or improvements made to the surrounding grounds. This work will sometimes impede the line of the original pipe work and it is advisable to remove this from future obstacles in case of emergency repairs. This can be done by diverting new pipe work around proposed structures and away from future hazards. This work also covers mains extensions for extra requirements and demand from an existing supply.
