PVCu Underground Drainage Access Points & Chambers

A well-designed underground drainage system must include suitable access for inspection, maintenance, and cleaning. At Pipestock, we supply the full range of Polypipe PVCu underground access points and chambers, designed to provide safe and convenient entry to your drainage network while fully complying with UK regulations.

• Inspection – allow visual checks of the system to ensure smooth operation.
• Maintenance – provide points for rodding, jetting, and clearing blockages.
• Compliance – UK Building Regulations require access at junctions, changes in direction, and specific intervals along pipe runs.
• Safety – purpose-built chambers reduce the need for excavation when the system needs attention.

• Rodding Eyes – small access fittings with removable caps, used at the start of a drain run or at sharp bends.
• Access Pipes & Bends – integrate into pipework, providing entry for cleaning equipment.
• Inspection Chambers – larger entry points designed for routine inspection and maintenance. These are usually fitted with a riser shaft and a cover & frame at ground level.

By including the right access points in your design, you ensure your drainage system is both serviceable and regulation-compliant.
