Hi,
I flushed a radiator and lost pressure in the system. I can't seem to find the filling loop. Under the boiler there are 2 black valves either side of the yellow(gas) valve but I don't see any filling loop or a space where one would go.
The first 3 pics are the boiler and the rest are the upstairs water tank.
