Good product, poor design of bleed valve inlet attachment
This product iz designed to be easier than the bottled version for adding quickly to a sealed heating system, but it needs caution if adding to the bleed valve of a radiator.The supplied attachment is brittle and fragile and snapped off in the valve, necessitating removing the whole nut and cleaning out the threads so as to be able to re-tighten the bleed screw.Ironically this leaves the large thread which you can attach the sturdier screw on tap to, just as if you were adding this via the filling loop on boiler.At the end of the process (which is easy) you are still left with the need to swap over the filling nozzle with the bleed valve. Advice: do this quickly as it’s likely you’ll have a full radiator again (unless you drained the whole system down).The product itself seems good, but I’d be wary trusting the fiddly valve inlet for this job.
