Suppliers, retailers, homeowners, consumers, sellers, importers, parallel importers, sole agents, distributors, wholesalers, manufacturers and installers shall ensure that the water fittings have been tested for compliance in accordance with PUB’s stipulated standards and requirements.
Water fittings such as taps and mixers, dual-flush low-capacity flushing cisterns and urinal flush valves/waterless urinals are required to be labelled under the Mandatory Water Efficiency Labelling Scheme (WELS) before they can be offered, displayed or advertised for sale and installation in Singapore.
From 1 Jan 2022, the Mandatory WELS shall be extended to include WC flush valves with a flush volume of not more than 4.0 litres per flush, and only WC flush valves of 2-ticks ratings or more shall be allowed for supply. From 1 Jan 2023, WC flush valves installed at premises shall be of minimum 2-ticks or more under the Mandatory WELS.
From 1 Jan 2022, only commercial washer extractors, commercial dishwashers and high-pressure washers that are registered under the Mandatory WELS and fulfil the mandatory water efficiency requirements shall be allowed for supply in Singapore.
With effect from 1 April 2018, Certification Bodies accredited by the Singapore Accreditation Council (SAC) under CT19-SAC Criteria for Certification Bodies (Water Efficiency Labelling Scheme) will be processing the applications and submitting them to PUB for WELS registration.

No person shall advertise a water fitting for supply, unless the water fitting has been tested for compliance with the standards and requirements stipulated by PUB. This applies to all water fittings.
For water fittings and appliances under WELS, no person shall advertise them unless the water fittings and appliances have been registered under the scheme. They shall be affixed with WELS label or the label information.
The requirements for sale and supply of water fittings and appliances apply to physical retail shops and suppliers’ showrooms, including online portals or resellers, as long as the fittings are for supply (i.e. display, offer-for-sale, advertise, loan, lease, consignment, hire or hire-purchase) in Singapore.
The Water Fittings Registration and Information System is a newly launched programme by the Singapore Sanitary Ware Importers & Exporters Association (SSWIEA) in late 2021. This registration system allows SSWIEA to assist and facilitate in the checking for compliance of water fittings to ensure that these products have been fully tested to PUB’s requirements.
The list of products published in SSWIEA’s website is for industry’s reference, and should not be in any way deemed as products being approved by PUB.
PUB conducts checks and surveillances on both physical premises supplying water fittings and online portals, and will not hesitate to take strict enforcement action against parties who do not comply with PUB’s requirements and regulations.
