Clunking boiler noises

insertclever

Hey there,

Wondering if anyone can confirm my theory. Now I'm not a plumber or anything so I could be way waaay wrong.

Yesterday one of the towel heaters in the house sprung a pinhole leak and ever since the heating doesn't seem to be working. If I turn the gas heater on now, there's agurgling sound, followed by a clunking sound coming from the hotpress.

Just after the gas boiler shuts down, the pin hole leak will start sprouting water and air making the same noise as if bleeding a rad.

My theory is that the hole is large enough to make the prssure drop completely in the system (the pressure gague seem stuck on 0) causing the system to shut down.

Is there any sanity in above theory or am I being an idiot? And if above is plausible is there a way to completely shut this rad off from the system so water neither comes in or out? I did turn the heat control valve completely down to 0 but this does not seem to stop water/air from spewing out from it and causing the system to shut down.

Any thoughts on above would be great!

Close both valves on the towel rail, repressurise and vent your system.
The leak is probably caused by lack of inhibitor, or positioned too close to the w.c. and getting sprayed with piss.

As poster says turn both sides off. You will have to use an adjustable wrench to turn the other one off.
Your system must be in a poor state if this happened.
