have had a look around and i can't find a drain point to flush my system , i have however found a red stopcock below the boiler which is connected to both the flow and return pipes to and from the boiler , can this be used to isolate the boiler instead of using the red and blue plastic taps , would i fit the drain off point on the return pipe then use the filling loop to flush the water through a hose attached to the new connection, not familiar with different fittings , what would be the best set up ?
