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 ;-)
I've used the exact same method.
The manufacturer's instructions generally involve injecting against
the pressure of the system - i.e. close valves, remove vent screw, fit
cartridge, open a valve and inject. The problem is that the
nozzles do not seem to make a perfect seal so water tends to squirt
out. Dropping the pressure and injecting into a wholly or partly
empty radiator works much better.
