TMV2 APPROVAL

INFORMATION TO BE INCLUDED WITHIN THE INFORMATION AND MAINTENANCE DOCUMENTATION.  

The Secretary of the Scheme has prepared this list after consultation with the members of Technical Assessment Panel and with the approval of the members of the BuildCert TAP liaison Group and the Industry Forum.

1.     Operating conditions of use, pressure & temperature (hot & cold) Table 1 in BS EN 1111 and   or 1287.

2.     Statement that valves operating outside these conditions of use cannot be guaranteed to operate as Type 2 valves.

3.     Its designation of use L.P if tested against BS EN 1287, H.P if tested against BS EN 1111 and H.P and L.P if tested against both documents.

4.    Valves approved for designation of use H.P only, must state: - If a water supply is fed by gravity then the supply pressure should be verified to ensure the conditions of use are appropriate for the valve.

5.    Recommended maximum set mixed water temperatures for applications of use, including the recommended safe water temperatures for children.

6.   Information upon the installation of the valve, this will include: -

• Requirements for valve accessibility to commission and maintain the valve

• Maintenance instructions

• If isolation valves are not provided then a statement is required that states ‘The fitting of isolation valves is required’ and identify preferred location.

• If strainers are not provided then a statement is required that states ‘The fitting of strainers is recommended’ and identify preferred location

7.   Information upon the commissioning and testing of the valve, this will include:

• Method of adjusting the mixed water temperature

• Method for commissioning the valve.

• Statement that ‘the mixed water temperature at the terminal fitting should never exceed 46°C’

• Method and frequency (1 year maximum) for performing the In-service tests

• Information on residual water flow during the cold water supply isolation test

8.   Reference be made to the ‘Water Supply (Water Fittings) Regulations 1999.

9.   Valves approved for low pressure tub/bath applications that only achieve the minimum flowrate requirement at a supply pressure of 0.2 bar must indicate that the minimum supply pressure for tub/bath applications is 0.2 bar. 

Note: The BuildCert TMV Scheme has produced an I&M template that can be used by license holders to fulfil their requirements of information that must be included within the Installation and Maintenance (I&M) documentation supplied with the TMV2 approved valve. To view the template, please click here
