Well so far my day has been.....drain central heating system replace a leaking / stuck radiator valve and add a new better thermostatic valve, refill it bleeding all rads. All ok...put the sentinel pressured refill canister into the system top up feed or tried to but as my system pressure was greater than the gas cannister it did not work, funny it diid the last time in seconds...just would not enter my system...should have done it when no pressure probably....ah well wasted that .
So used the liquid version and added it via the magna clean system. --- twice as the magna sysyem only takes about 1/2 litre at a ttime...fiddly little job but not difficult Job done. Why do they not fit isolator screws on rad feeds like you do on a cold tap feed from the supply FFS...if I ever haveto drain the system down again, I will fit these to each radiator input pipe so the job will be 5 minutes , no system drain and you won't need to replace sentinel every time at £18 a pop approx. I once tried the freeze input pipe angle ...loada bollox and waste of money that was!
Tha'ts yer DIY plumbing lesson for today folks...now gonna have a beer...or three!
