Product details

20mm Black Irrigation Pipe is designed to run underground to invisibly connect the irrigation system together. The irrigation pipe may be used to run from the water supply to the valve box or from the valve box to popup sprinklers or to connect between flower beds.

To comply with the UK Water Regulations, irrigation pipe is coloured black to ensure that it can be easily differentiated from drinking water pipe, which will always use blue underground pipe.

For strength and durability underground the irrigation pipe is manufactured using either Medium Density Polyethylene (MDPE) or High Density Polyethylene (HDPE) pipe. This has a thick pipe wall to prevent crushing and damage when buried underground.  In private gardens we recommend the pipe is buried at least 300m underground and on construction sites we would recommend the black irrigation pipe is buried underground at least 500mm.

Medium-density polyethylene (MDPE) pipes are versatile and widely used for various underground applications. These pipes are specifically engineered to withstand the harsh conditions and demanding requirements of buried installations. Their key uses underground include:

1. Water Supply: Blue MDPE pipes are commonly used for underground water supply networks. Their resistance to corrosion and durability make them an ideal choice for safely transporting potable water to homes, businesses, and communities.

2. Gas Distribution: Yellow MDPE pipes are extensively employed for underground natural gas distribution systems. Their strength and leak-resistant properties ensure the safe and reliable delivery of gas to residential and commercial properties.

3. Irrigation: Black MDPE pipes serve as the backbone of buried irrigation systems. Their flexibility and resistance to root intrusion make them well-suited for efficiently delivering water to horticultural and agricultural fields and landscape irrigation systems.

MDPE pipes are favoured for underground applications due to their exceptional performance, longevity, and ability to withstand the challenges of buried environments, ensuring reliable services for water, gas, electricity, and more.
