A quick pre-procurement check
Check the GA number, brand and complete model against the product. Related models in the same range are not automatically covered.
One GA letter can cover several sizes or configurations. Match the water-supply system, size and fitting classification to the work.
Confirm that approval is not expired, suspended or removed, and re-open the official record before a formal submission or inspection.
What is General Acceptance?
Pipes and fittings used in Hong Kong inside-service and fire-service installations must meet Water Authority requirements. Accepted products receive a General Acceptance record; its official model, size, use, status and letter define the approval scope.
One GA number may contain several models, sizes or configurations.
A record may be updated when approval expires, is suspended, reinstated or removed.
JACO provides the search interface; WSD remains the authoritative source.
Frequently asked questions
A “water paper” usually means a WSD General Acceptance (GA) record. It pre-approves a specific plumbing product against relevant statutory material standards and carries an acceptance status and expiry date. WELS indicates water consumption and water-efficiency grade so buyers can compare water-saving performance. They serve different purposes and do not replace each other; check the GA record and WELS registration separately when relevant.
No. General Acceptance normally applies to specified models, sizes, fitting classifications and uses. Check every exact product record, even within one brand or range.

Expired means the acceptance period has ended; suspended means acceptance is temporarily paused; removed means it has been withdrawn. Review the official details before use.
