Old cast iron column radiators flow return-urgent help

[joni os]

When the 10 to 12 piece is removed. I would hammer 1 towards 7 or 9 towards 3 which ever gave the most bite.

I wasn`t trying to undo it, more like folding it in towards the centre thus releasing the "grip".

Hi everyone, been advised to use LSX sealant when fitting the stop ends-is this the best one do you think?

Wouldn`t use LSX in this application.

These rads are not designed to work at 3 bar pressure which is the safety valve setting on your combi.
They have spent there lives so far in open vented systems with a head pressure of a floor or two i.e. 0.6 - 1bar.

If I were you I would be testing them first as SimonG suggested, then I would fit a safety valve with a lower setting to the system!

BTW - TBOE for the con's

pressure wont be a problem ive had cast rads with 8 floors on them all the big buildings in london originally had cast iron rads

Thanks everyone-will try the hacksaw method.

The rads have only recently been removed from buildings where I understand they were working but boiler being fitted Sun so will mention about the safety valve as I don't want to ruin (any more!) of them. Is a sealant necessary for the stop ends on the rads or just PTFE and if so whats the best thing if LSX isn't good for this?

That paste he's using isn't much like boss white though? The guy in the video seems to think the paste is just for lubrication. Anyone else here tried hemp without boss? It don't seal lol!

I like using Boss and hemp. Makes me feel old-school 🙂
