This 20mm MDPE mains water supply pipe comes in coils of 25m, 50m, 100m & 150m, complete with an end closure at each end to protect the pipe from any dust or unwanted substances from manufacturing to installation. Also known as alkathene, this flexible & lightweight pipe is made from MDPE and fully compatible with approved mechanical, push-fit, compression and electrofusion jointing techniques.
These pipes are produced as a single layer pipe wall construction, with a PE80 black inner and a PE80 colour coded light blue outer. The light blue indicates this is suitable for below ground potable (drinking) water mains supply distribution, popular for both domestic and commercial properties. Also suited for use in pipeline rehabilitation projects and in no-dig & open-cut installation methods. For non-potable applications, you will need a MDPE with a black outer.
Manufactured by Radius Systems provides the installer with a dependable product that will perform. Unlike previously used materials such as iron or copper, MDPE water main is made from corrosion free material meaning it will not degrade to any great degree with age. Naturally, making it the UK’s manufacturer’s most common choice of material for water pipe. If you need to connect your MDPE to older materials, adaptors are available.
Specifications include SDR 9 with a maximum 12.5 bar operating pressure, WRAS approved PE80 materials, approved under regulation 31 of the Water Supply (Water Quality) Regulations 2000, BS EN 12201-2:2011+A1:2013 (BS EN 12201 replaced BS 6572).
If you plan to run any water service underground, we would always recommend that the water pipe is buried in the ground inside a blue water duct system. A duct is designed to protect the pipe from damage and alert others to the presence of duct in the ground. Water caution marker tapes are commonly used as additional indications, alerting presence of the pipes. If this is your first time installing ducting, we would always recommend attaching a second drawcord to your pipe as this will enable you to easily install replacements at any point in the future, if required. Your duct system may also need duct access chambers depending on your project, which come in a various sizes to suit.
