THE THOROUGHFLUSH IS A DEVICE THAT WORKS BY DIVERTING WATER AROUND THE SYSTEM USING WATER FROM THE COLD MAINS SUPPLY VIA A SUITABLE DOUBLE CHECK VALVE (SEE THE BSEN 1717).
How it Works
The water supply is connected to the inlet connection, connections A & B are connected to the heating system pipework via your preferred method (see diagram above). The outlet connection is directed to a suitable foul drain to dispose of wastewater. Setup is possible in less than 5 minutes.
Water flows through the system in the direction selected on the device removing contamination and debris as it passes through the pipework and radiators. Water flows back to the device via the opposite connection and exits via the outlet connection to a foul drain. Flow can instantly be reversed by turning control ¼ turn.
Other tasks can be completed when flushing (i.e. wiring controls, tidying up or drinking tea) as there is no risk of tanks overfilling or pumps running dry.
Adequate flow and pressure are required from the mains water supply for this device to operate correctly. It’s that simple and very effective!!!

This device complies with flushing methods as described in BS 7593:2019 Code of Practice for the preparation, commissioning and maintenance of domestic central heating and cooling systems. If you have any questions, please fill in the form on the contact pageDownload Instructions (PDF)
