Plumbing help for Towel rad
hobzy - 29/11/08 at 03:02 PM

Sorry its not car related but figured someone on here would have an idea and my plumber mate is on holiday...

Just trying to fit a towel radiator to the bathroom, something I assumed would be a piece of cake having fitted new rads everywhere else in the house with no issues.

Trouble is, the threads were at each end (its the ladder style) so the valves had to go in facing sideways if you get my drift, and I had to put a 90 degree on the existing pipework to meet it. All was going well until I stopped and looked at screwing the metal fitting into the rad that thermostatic valve attached to - no lip or washer to stop it leaking? OK thought I, give it a go with PTFE tape and do it up flippin tight... not a hope! As I expected, dripped straight away. Clearly I am missing a vital piece... any ideas what?

The male fitting to thread into the bottom of the rail and screw the valve into, the bit with the big nut which has an allen fitting inside to tighten it into the rail or radiator. It comes with the valve. The big nut on the right in this picture, put some Boss white on the threaded bit and dog it up.

Cheers,

hmm mines not quite like that:



I've screwed it in as tight as it will go with a big adjustable but it still leaks from the thread that's actually in the rad...

Its only a little drip but I can't physically do it up any tighter. More PTFE or is that sh@te and go and get some Boss White?

I have found that wrapping the threads with PTFE tape until you cant see the threads seems to work. As the valves are fitted from below you wont be able to see the PTFE tape sticking out.

Remember plumbing is rough as F**k nothing is the same size and is poor fitting and the only tool you need is a shifter.

then jet blue plus (or equivilent) on the compression fitting.

i fitted the same ladder type in bathroom couple of months back and it leaked and leaked for ages kept tightening and then some but nothing helped, ended up stripping it all and starting again plaenty ptfe and it ended up rosy so all i can say is strip it clean it all off and plenty ptfe

cheers

without stating the obvious, make sure the ptfe is wrapped the correct way incase it unwinds!


hobzy - 29/11/08 at 07:15 PM

He he, first thing I checked! OK, cheers guys - looks like its going to need copious amounts of PTFE. To handy saucepans tonight mean at least I can sit on the loo without sticking to the seat

if you look inside the section your fitting to the radiator you will see that it is heaxagonal you neetd to tighten this with an allen key toget maximum purchase on it and as others have said plenty of ptfe

See, on this set of valves, it doesn't have an Allen hex inside, but it does have a 4 sided section on the outside... Its in as tight as it will go with a big adjustable. Just must be the thread - the rad wasn't exactly expensive...PTFE by the roll tomorrow
