The Kenya Bureau of Standards (KEBS) confiscated unbranded polyethylene (PE) pipes in Machakos County after finding they lack permanent markings required for safety and performance verification.

KEBS said its Market Surveillance Team seized the pipes on Tuesday, November 10, noting the absence of printed technical details such as pressure ratings, material designation, SDR ratings and batch numbers.

The agency explained that without these markings, consumers, contractors and water utilities cannot confirm whether the pipes meet required specifications, increasing the risk of failures.

KEBS warned that using unmarked PE or high‑density polyethylene (HDPE) pipes could cause bursts when subjected to pressures beyond their capacity, leading to water losses, property damage and expensive repairs.

The bureau cited KS ISO 4427‑2, the Kenyan standard governing polyethene piping for water supply, which mandates clear, permanent markings to identify performance characteristics.

According to KEBS, these markings enable buyers to verify that pipes are suitable for intended applications and comply with safety limits.

The seizure coincides with World Quality Week, during which KEBS reaffirmed its commitment to consumer protection through enforcement of quality standards.

KEBS announced it will continue removing non‑compliant products from the market and urged Kenyans to verify product compliance before purchase.
