System cleaner

[LUCIALIA]

How do you add a cleaner to a sealed combi system, can it simply be poured into the filling loop?

 

[Puddle]

You can get a pressurised cleaner in a can and you can inject through the filling loop,most system chemicals can be purchased in this way now

 

[LUCIALIA]

the one I have is simply in a plastic bottle

turn the valves of one rad off, drain it, tighten valves, put cleaner in rad, open valves.

if you have a towel rail thats is the easist rad to insert the inhibitor into as you just whip off the cap at the top of the rail having let some water out first
