I have a question about this valve that's part of the filling loop on my boiler, I'm guessing that the black plastic handle should be easy to turn and that you should be able to turn it to the vertical position?
In the horizontal position it should supply the raising mains to the 'water in' only connection below the boiler, if you needed to top up the bar pressure of the boiler, turning it a 1/4 would also send water to the 'return pipe' at the boiler. If the handle were fully vertical, should it stop the water going down both those pipes?
Sometime ago I did find a leak at the other end of that filling loop, you can see the PTFE tape that I used to stop it,....my guess is that valve has failed, sending water down that braided hose all the time, hence why the bar pressure on my boiler keeps raising.
If it is ********, so is the 'water in' or 'return in' shut off valves on my boiler because whilst I had the diverter valve off, water kept trickling in despite both valves being turned off.
