MDPE, or medium-density polyethylene, is ideal for water pipework as it is light, durable, and resistant to corrosion and stress cracking.

As a pipework system, MDPE was specifically designed to carry water for human consumption. Therefore, no contaminants can be present, either through the build-up of bacteria or from rust generated through corrosion. MDPE is manufactured with a smooth bore, to prevent the accumulation of bacteria. As a plastic, it obviously won't corrode, but it is also resistant to environmental degradation.

MDPE was previously known as alkathene, although that name is still used in the industry today, or is often shortened to just PE.

What is Regulation 4 of The Water Supply (Water Fittings) Regulations 1999?
 
Regulation 4 of The Water Supply (Water Fittings) Regulations 1999 is a key provision that focuses on the requirement of providing water fittings that do not cause waste, misuse, contamination, or excessive consumption of water. This regulation plays a vital role in ensuring public health, water conservation, and the integrity of the water supply. Under Regulation 4, it is essential to use only water fittings of an appropriate quality and standard. For the purposes of Regulation 4, a water fitting is of an appropriate quality or standard only if it meets one of the following criteria:

• Bear an appropriate CE marking in accordance with the Directive.
• Conform to an appropriate harmonized standard or European technical approval.
• Conform to an appropriate British Standard or some other national specification of an EEA State which provides an equivalent level of protection and performance.
• Conforms to a specification approved by the regulator.

Compliance with Regulation 4 also includes proper installation practices, regular maintenance, and prompt repairs to prevent leaks and water wastage. By adhering to Regulation 4, the regulations ensure that water fittings are safe, efficient, and environmentally responsible, promoting public health, water conservation, and the sustainability of water resources.

What is ISO 17885:2021 - Plastic Piping Systems?

ISO 17885:2021 - Plastics piping systems is an international standard that provides guidelines for the design, installation, and maintenance of plastic piping systems. It covers various aspects, including materials, dimensions, pressure ratings, and testing requirements. The standard ensures that plastic piping systems are manufactured and installed in a safe and reliable manner, promoting durability, efficiency, and environmental sustainability. Compliance with ISO 17885:2021 helps ensure the quality, performance and integrity of plastic piping systems, contributing to the safe transportation and conveyance in this instance of Water For Human Consumption, Water For Irrigation and Waste Water.
