On my Turbomax, i am wanting to mains flush the return leg of a radiator in an upstairs bedroom. I removed the rad a bit ago to decorate and immediately the boiler started cutting off after reaching the temp set on the boiler. I suspect that some sludge or crud has got into the leg as quite a bit of black water came out of the rad and now its slightly restricted. All the rads get warm/hot etc but before i dive into a powerflush in the new year, i want to do as mentioned above.
It has a filling loop fitted but i am just wanting to clarify that i can close all rads and the flow isolating valve and then water mains flush via the CH return valve upto the radiator upstairs (draining from the radiator valve).
I know some will say just powerflush etc but id like to try this first before forking out for it. Also ive used x800 cleaner an loads of junk was collected in the magnaclean which i've cleaned 3 times, each times less and less being removed. I've checked the ntc sensors, replaced the pump with a another one, checked the DV isnt stuck etc. And the hot water works fine
Thanks
