soldering Copper to chrome pipe

[ParrDi Gras]

Hi Guys , im about to replace two bathroom radiators with chrome towel Rads. My existing CH pipework is 10mm and im going to have to use a reducer from the 15mm Chrome pipe which is going to go into the radiator valves.(dont ask me why I cant just use the plastic chrome like snap tube to cover the 10mm pipe and use a reducer inside the Valve, as the wife). anyway should I remove the chrome from the copper pipe before soldering into the reducer and then onto the 10mm pipe or will it make a good bond anyway.

thanks guys

You have to remove the chrome first, which is a pain in the neck.

If you can hide the joint (under the floor for example) then you can use a compression reducer and no one will be the wiser!

file the crome off the pipe until you have removed it all were u are going to solder .
then put power flux onto pipe and solder it and it will be a good joint.
( any flux will work but powerflux is my personel prefernece )

if using power flux you can sometimes get away with not filing the crome as the power flux removes the crome but if pipe is hidden your better off filing it to be sure

Thanks for the advice guys, I will cut my pipe and bend the pipe something to length and stick it on the lath at work , using abrasive paper around should remove the chrome easy enough as it spins round . cheers again

never use compressions fittings under any floors , if working on rad valve in the furture , nuts will loosen off ,

i agree best to use solder fittings

All sorted guys , chrome came off pretty easy with me holding the abrasive paper as the pipe span on the lath. Took your advise and soldered all the joints , made up with the job. However I have just opened the towel radiator I purchased some time ago now and am about to fit it. Can anyone explain the best way to flush the system to get all the s*** out of the radiator. Ive bought the chemical to flush the system and some inhibitor to put in once flushed. I have a combi boiler and I can easily drain the system and re fill but not sure of the easiest way to flush the system??? is it as simple as opening the drain valve on the boiler and pouring the chemical and water into the Towel rail??? would appreciate some advice cheers guys

Yes mate just turn your boiler off, connect hose up to the drain off cock and drain away. I also like to when finished to shut all the rads down bar one and turn water back on then go round all rads shutting one down opening up another. You will find the mains water pressure will help clear out alot of carp. Also change the washer on the drain off cock before filling back up often fail.

Towel rail is ideal for adding chemicals
