** I am not a plumber. I do not take any responsibility whatsoever for the information in this video. If in any doubt, consult a professional plumber. **
My old radiator was imperial, the new one is metric.
There is now a gap between the old valves and the new radiator.
I could not work out how some 'Radiator Tail - Telescopic' systems worked when looking online.
I fitted one and it leaked.
This one worked first time, so you save someone else about 5 hours, heres the video.... taken by my six year old....

Great video thanks. Saved me hours of heartache. Made replacing old 5ft radiator with new 1400mm very straightforward without needing new pipework. Compliments to the cameraman too.

Good vid,just a tip though, you dont need to put ptfe tape on the threads of compression fittings ,it serves no purpose at all,put the tape on the olive not the thread.

Telescopic radiator valves are a leak waiting to happen. One can buy a fixed length version which can easily be cut to the correct length with a pipe cutter. PTFE around the thread on the valve is also a NO. It needs to go around the olive as this makes the water seal. The nut and thread just mechanically holds the joint together

@amblonyx9516 Жыл бұрын

Agree - the fixed type has a longer thread into the rad, and costs less, whereas the telescopic type relies on a rubber gasket. Fit once, never replace!

Not correctly installed. Ptfe tape around the lockshield valve thread is not the way to seal that connection,. The olive makes the pipe seal, and a touch of jointing compound or a few turns of Ptfe on the tail spigot us the correct way to a perfect joint. Also, I can see the telescopic tail has an O ring seal so no Ptfe required there, just a slight smear of silicone grease.

@ericmamet9893 2 жыл бұрын

Please bear with me, I am a complete plumbing beginner... What you call the "olive", is it the black rubber seal? So on one side, the seal is ensured by the rubber. What about the other side? Is the brass thing enough as well? Is PTFE required purely for hard metal to hard metal connections? Do we need PTFE tape anywhere in this case?

@westwonic 2 жыл бұрын

@@ericmamet9893 The olive is the copper ring that fits around the copper pipe, looks like a wedding ring, and is used in all compression type fittings (those with a nut and thread). If you are screwing a radiator tail into a radiator, and the tail includes an O ring, then a little silicone grease is required to ensure a good fit at the radiator . The other end of the tail usually includes an olive as it is a compression type fitting.

@westwonic 2 жыл бұрын

For info, the olive is heat treated at the factory to soften it, so when the compression fitting is tightened it is squeezed between the pipe and hard machined metal face of the fitting. To ensure a completely weep free joint, smear jointing compound at the olive /pipe joint facing the machined metal face, or a few turns of PTFE can be used.

@cap7629 5 жыл бұрын

This video was very useful as I had to replace an imperial radiator for a new metric. I did not use the telescopic tail however, instead I used the rigid TRV extension tail as I read some reviews that said the telescopic tail was prone to leaking. Nonetheless, appreciate the time taken to put this video up.

@phil955i 2 жыл бұрын

I didn't know these were actually a thing until I noticed one of my rads leaking. Initially I thought it was one of the compression fittings on the valve, but when I took the rad off the wall I noticed one of the tails slides in & out. That's where it's leaking from. I have no idea how old that telescopic tail is though as I bought the house 7 years ago. Time for a new telescopic tail 👍

@badassbiker1974 Жыл бұрын

Good job, great video. I much prefer brass olives to copper ones, never had to apply ptfe tape on a brass olive. But if using the copper olives, I tighten the fitting down first (so the olive bites into the pipe and secures it) then unscrew the nut and apply the ptfe tape. Im no plumber either, but you could probably make an extension by fitting one side of a 15mm straight compression fitting into the Rad and then using the required length of 15mm pipe between the straight connector and the valve.

@@bobtahoma You are right, a properly tightened olive (about one quarter turn once it makes contact) should never need ptfe. You are best putting ptfe on when reusing an olive (like when there is no access to get it off) or of you have a leak from an existing olive then ptfe will usually fix it. As for copper or brass, both work but I too tend to use copper.
