Part G revisions for safety and efficiency in the home


The new edition of Part G (Sanitation, hot water and water efficiency) of the Building Regulations for England and Wales, effective from April 2010, includes the requirement to fit a temperature regulation device for the bath in new home bathrooms, to prevent scalding. Similar regulations have been in place in Scotland since 2006.

To achieve compliance with the new regulations, safety valve specialist Reliance Water Controls offers a selection of high performance TMV2 approved thermostatic mixing valves to suit domestic systems: the Heatguard? TMV2-2, DC2, LS2 and BF2-2. These valves provide precise and stable temperature control, protecting the user from thermal shock if either the hot or cold supply fails. They are fully approved by WRAS and Buildcert to the TMV2 scheme for thermostatic mixing valves in domestic properties and meets the needs of the home bathroom.

A thermostatic mixing valve can be fitted easily near the outlet and provides the same level of anti-scald protection as a thermostatic tap or bath/shower mixer but at considerably lower cost, and it allows the choice of budget and style for the bath taps or fittings to remain flexible.

The Part G revisions also require that new domestic bathrooms are designed for water economy, based on a maximum usage of 125 litres of wholesome water per person per day. Reliance has long experience at the forefront of developing water control technology to ensure an efficient system, and their range includes devices to control flow or pressure, or to meter consumption which encourages economical water use.
