I've got a heated towel rail which is fitted in parallel with a radiator in the bathroom (the pipework tees off below the radiator flow/return pipes and goes into the towel rail valves). There used to be a blockage somewhere in this, which meant that the top couple of inches never got warm water through. This wasn't an airlock, as I could unscrew the vent valve completely so that the screw came out altogether, and no water came out.
After putting some sludge remover into the heating system, it seems that the blockage has got worse, as the whole towel rail is now cold. (I assume that a load of muck has been freed up from elsewhere and has got into the towl rail and blocked it completely). I tried shutting down the valves on the radiator in order to try to get more water through the towel rail, but the bottom couple of inches next to the flow valve gets luke warm, but that's as good as it gets.
I'm wondering about taking the towel rail off in the hope that I can clear it out, but I'm not sure of the best way to do this. Is it likely that I'll shift anything just by putting a garden hose into one of the valve tails and giving it a good blast of water? The design of the towel rail is a simple 'traditional' style, with two uprights and two vertical bars.
Thanks in advance for any suggestions!
