At Polypipe Building Products, safeguarding water quality is a top priority.
That’s why many of our systems are REG4 approved, meeting the requirements of the Water Supply (Water Fittings) Regulations 1999 across England, Wales, Scotland, and Northern Ireland.
REG4 approval - often verified through WRAS (Water Regulations Approval Scheme) - confirms that our products are safe for use in potable water systems. It ensures they do not contaminate drinking water, compromise system integrity, or pose health risks. Our REG4-certified solutions, such as the PolyPlumb® Enhanced range, are rigorously tested for material safety, mechanical performance, and long-term reliability.
Whether you're working on a hospital, high-rise, or residential development, Polypipe’s REG4-approved products offer peace of mind, compliance, and trusted performance - every time.
