Sludge in Radiator

[Curlylocks5411]

I have sludge in some of my radiators.

Is there an easy way of getting rid of it without taking the radiator off. It's too heavy for me to do on my own?

This is probably the best way to get all of it Curly .....................

Are you joking? You an agent?
How did we do this easily before ruddy Powerflush tried to fleece us all?
Drain down a couple of gallons by draining at a drain cock or radiator connection (catch the stuff well .. it may be black and WILL stain ANY carpet) You may have a sealed system so take into account refilling/pressure/fill loop, etc. Turn off water rising main to header tank if fitted (or hold ball valve up)
Add Fernox products as described here ...

Run the system hot for the day, and drain and refill completely adding inhibitor.
Easier than it sounds. Made easy by a decently positioned drain cock, to which you connect a hose, and the thought of saving £300 on Powerflush.
