Plumbing in cast iron radiators - replacing K2's

[jaydebruyne]

never done cast irons before. Is there anything special about them? One of them is a 70kg one which comes in 2 halves. They just take standard valves, 1/2" no?

 

[ShaunCorbs]

No will be 3/4 unless they've been changed

And whose putting them together/ leak testing

If it's the old style you need special tools

 

[king of pipes]

New or reconditioned jay plan your pipework if running on the surface they could be 3/4 BSP tappings but a 3/4×1/2 black iron bush will sort that as shaun said you will need specialist tools for the older style rads fixing can be tricky if they are wall mounted with no legs good luck bud cheers kop.

I refitted 2 of these bad boys. After another heating engineer that removed them went AWOL. There is a place up north that I would recommend that reconditions them and puts them together. I would tell you the name if I could find the bloody paperwork for them. (Let me know if you want it and I will have a look) nothing special about them just really heavy and awkward to move (but pretty to look at) so make sure you have an extra pair of hands around. Mine were going onto iron pipework so a bit more tricky with the black iron adaptors. You will be well pleased with yourself once you have done them.

Apparently the company that sold them are giving them the tool to connect the two halves.
I'll pick up a couple of 3/4 to 1/2 bushes in the morning.

Iron not brass would be best

And I would leak test them first once there made up and on the wall

No idea if new or reconditioned. I'm hoping they have feet!!

Yup. Am hoping my local plumbs have them. How are the 2 halves of the 70k rad joined then?

Don't you need two people trust me you do

I take it there are no middle feet then :/ I don't have anyone else, unless the guy is going to be in to help.

You need two people they flex like crazy and can crack / split

I would rather say no to the job if there's not going to be someone strong helping you

 

[jaydebruyne]

lol I'm doing three of the beggars tomorrow. 2 aren't as big and don't need putting together. What's the best compound to use on iron fittings? I was gonna use loctite thread and jetblue?

 

[ShaunCorbs]

Stag part b
Boss white

Put them together before on the wall

For your sake I hope there alu

Sh*t really? Ummmm pooh. Not sure what to do now. I need to see how they connect. I'll see if google has any images.

Some do some don't depends on length

 

[jaydebruyne]

Just watched a vid online of how to put together. I reckon the rads will be new. The end caps look like inch thick?

 

[ShaunCorbs]

End caps you mean plugs ??

 

[jaydebruyne]

Yeah.. I'm just gonna have to assume the custard has bought everything required as all I need to get is pipework..

Absolutely 15mm - not chrome as it's a temporary connection until they redo the flooring which will then all be hidden

Normally they are attached togetherfrom the inside. With large fibre washers and male connectors

 

[Harvest Fields]

Don't you need two people trust me you do

I tried to move them by myself. #badbackinthemorning

don't drop them on your toes either they might stay attached to your shoes

Can normally manage upto a meter one on my own but I'm used to it

Any bigger 2+ men did one once took 8 guys to lift and mount

I had to go to BES as plumb and parts centre did not stock the correct size of black iron I needed

Are iron rads plugs a standard size? Or can they differ?

 

[ShaunCorbs]

Should be stnd something like an 1" or 11/4" plug

 

[jaydebruyne]

Cool. I'll try and grab a couple sizes

 

[ShaunCorbs]

I would have a look at the rads before you get any if you could
