This updated guide incorporates industry feedback from nearly twenty years of flushing and cleaning using BSRIA's Pre-Commission Cleaning of Pipework guides. It is a revised edition of Application Guide AG 1/2001.1 (2004), 2nd edition, containing all the recommendations for design, installation, system flushing and chemical cleaning of pipework systems and a section dealing with the issues raised when connecting new pipework to existing pipework. The Guide is intended for designers and installers of recirculating heating and cooling systems and does not apply to hot and cold water supplies. Includes tests for pseudomonas. In particular, it aims to clarify the roles and responsibilities of the parties, improve the exchange of information between them and provide consistency between service offerings of the pre-commissioning cleaning contractors. Note that additional guidance on the sampling and analysis of system water, including during the pre-commissioning phase of the building life-cycle, will be included in a new British Standard.

Common customer questions & answers

QQuestion Which edition of BSRIA’s Pre-commission Cleaning guide should I be using?
AAnswer The current edition of BSRIA’s Pre-commission Cleaning guide is BG 29/2021. It was revised in partnership with the CSCA with input from an industry steering group, members of which are listed in the guide. It supersedes all previous editions of the guide. It is BSRIA’s intention that, in normal circumstances, BG 29/2021 should be used in preference to any superseded editions of the guide. Superseded versions of the guide are still available (see Revision History above) as they provide useful reference information for older projects. Users of BG 29/2021 should be aware that it is a guide, not a regulation. It is for individual project teams to decide whether to follow the guidance, and this should be made clear in project documentation.
