When selecting the required TMV, it is essential that it performs at the flow rate required for that application. Although TMV2 allows for ‘group mixing’ to multiple taps, the valve must be sized accordingly to meet the demand. An undersized valve may result in insufficient hot water reaching the tap(s). A 15mm TMV for each tap is recommended but if you wish to use a 22mm TMV for group mixing of two or three taps, please ensure flow rates can be achieved.
