More Information on Blue Twinwall Duct Pipe for the Protection of Water Mains when Buried Under Ground.

picture of blue water duct pipe

Coils of blue duct protect MDPE mains water pipe as they're buried underground. The pipe comes complete with a drawcord and coupler/joiner and has a ribbed outer surface and a smooth inner surface.

When the mains water pipes "pulse" underground, it increases the risk of wear and tear on the materials, and this can sometimes cause breakage or leaking. This is why it must be protected within a suitable ducting system.

It comes with a blue colour to warn anyone who may be digging up the ground that a mains water pipe is installed inside. A warning tape should also be used as further protection.

It is available as twinwall coils in lengths of 50m. They may be seen in sizes from 63mm to a larger diameter of 110mm. They also come with a drawcord making it easy to pull the blue mains water pipe through it with minimal fuss. It requires very little set up time, and it's impact resistant and is very flexible so minimal jointing is required. Twin wall products provide the benefits of a single-walled product together with vastly improved strength and durability. The coil meets is specified strength ratings by retaining the correct wall thicknesses.

All blue water ducting coils are coloured to match NJUG recommendations, for products in this category it's blue to signify that a mains water run is protected inside. We supply it in 6 metre lengths and 50-metre coils. The inside wall is smooth to prevent the water from run catching when it is pulled through the duct. If required, installing two pipe seals ensures a water tight joint.

The blue twinwall water ducting is made from the same machines as the other cable ducting systems that can be found within this category on EasyMerchant. The only real difference is the colour to warn anyone digging what is contained inside.

Access chambers are also kept in stock at EasyMerchant and can be found in the relevant section in the menu. We also stock the galvanised steel lids and covers to complete the system

Regulations for Installation:

⦁ Choosing the Right Duct Size

Where the water supply run enters a construction or runs under a construction, it has to be found inside the right duct for accessibility. The duct size used is most commonly in 63mm or 110mm in diameter. There must not be any markings for utilities on the duct, including gasoline, electricity, or electrical.

⦁ Laying the Water Ducting

The ducting for a supply pipe ought to be laid before the bases are completed to enable the run to be inserted within the protective twinwall once the foundations are finished. The duct ought to be laid below the final ground level of the property at a depth of 1350mm max and 750mm minimum.

⦁ Sealing the Duct

A sealant or a removable seal should be used at each end of the duct. Do not use an oil-based sealant, expanding foam, or another sealant that could harm the pipe. Some contractors use a thin layer of sand or cement, but care is required to prevent contact with the pipe. It could be better to utilise a 'sterile end cap' with a hole with a grommet to permit the pipe to pass through.

⦁ Backfilling

The backfill should be lined with selected earth or sand, not rubble. The trench must be wide enough for your pipework, using a distance of at least 350mm from services such as gas or electricity. If you haven't used an approved contractor, you'll need to notify the local authority when the pipework is complete so that they can set up an inspection. Until this has been completed, the trench should not be backfilled.

Note: Joints or fittings cannot be used to the supply run when inside a duct. Joints should be of an approved substance and not solvent-based.
