Hi,
This may seem a trivial matter to some but i have never done it!
My central heating is a sealed fully pumped system. I would like to flush it and add new inhibiter.
The flushing part i think i can handle. i.e. Connect a hose from the tap (check valvle) to the flow and a hose from the return to a drain.
How can i add the descaler? When it is fully flushed the system will be full of water...So how do i add the inhibiter? Probably the same way i add the descaler ;-)
Regards,
Rich
