Fittings And Standards For Water Service
All water fittings such as flushing cisterns, flush valves, pipes, pipe fittings, taps, valves, etc for use in potable water service installations in Singapore shall comply with the standards and requirements stipulated by PUB. Prior PUB approval for the water fittings is not required but suppliers, retailers and installers shall ensure that the water fittings comply with the standards and requirements stipulated by PUB and that their use in potable water service installations conform to the Public Utilities (Water Supply) Regulations and Singapore Standard CP48 : Code of Practice for Water Services. For flush valves and flushing cisterns, suppliers, retailers and installers of such fittings shall have to ensure compliance with the requirements on backflow prevention and wastage of water as stipulated in the Public Utilities (Water Supply) Regulations and the Singapore Standard CP48 : Code of Practice for Water Services.
Any clarification or feedback can also be directed to the above address.
A water fitting shall be deemed to comply with the stipulated standards if it is certified or tested as complying with such standards by a conformity assessment body (product certification body/testing laboratory) accredited by the Singapore Accreditation Council (SAC) or its Mutual Recognition Arrangement (MRA) partners. Separate approval from PUB for the water fitting is not required. However, fittings must be supported with valid, complete and full test reports and certificates. Suppliers/retailers shall ensure that these test reports and certificates of all the water fittings which they offer for sale, advertise, display, sell or supply are properly kept and must be produced for verification upon request by PUB. PUB continues to conduct checks and will take action against non-compliance.
PUB reviews the standards and requirements stipulated for water fittings regularly to allow for innovation and changes in technology and to ensure relevance.
