In accordance with Water Regulations, supply pipework should be flushed at full bore to completely remove any debris and organic matter prior to commissioning all mixing valves and shower valves. The Horne flushing kit enables effective flushing after installation of the TMVs or showers.
Flushing adapters are available for all options of HORNE 15, HORNE 20, Heatstat T2, HORNE 25 TMVs and the HORNE TSV1. The flushing adapter enables the newly installed pipework to be flushed clean of any debris without passing the debris through the TMV and risking damage to the sealing faces.
Fitting the HORNE Flushing Adapter
The strainer cap on the HORNE TMV is removed along with the mesh strainer basket on the cold side of the mixing valve, and replaced with the flushing adapter (see useful documents). It is essential that this is done before water is run through the valve.
The flushing hose is then attached to the adapter and positioned so that water can run to drain. The water supply is turned on at the isolating valve and allowed to run until the water is clean and no further debris is evident. Repeat this procedure for the hot water supply.
Horne TSV1 shower panels are flushed in the same way (see useful documents).
DO NOT flush the pipework by removing the internals of the mixing valve and flushing water through the empty or dummy valve. The pressure drop across the valve and the downstream tap will prevent the water flow attaining maximum velocity and this will not be sufficient for effective cleaning of debris and biofilm from the pipework.
