Your questions on non-compliant pumps answered

Following revelations that the Office of Product Safety and Security (OPSS) found over 85% of domestic heating circulators it inspected last year were non-compliant, Wilo is urging distributors and installers to check pumps hold the right certifications and markings before stocking or installing them in homes and heating systems.

Installing non-compliant pumps could pose a safety hazard to consumers and last year an incredible 38 domestic heating circulation pumps were delisted from sale due to being non-compliant.
