Replacing Copper Pipe Compression Fitting on Release Valve

Ziycon

Looking for a small bit of advice, the current compression fitting on the release valve for the central heating is leaking so I purchased a new one, I have tried to remove the old compression ring and bolt but the compression ring is not moving, anyone have any suggestions?

There is a slight difference in the release value, the old value has a flat base on the threaded end where as the new value has a slightly angled base so it's not a case I can just swap the valve, the old compression ring needs to come off..

My last resort option is to cut the pipe below the soldered joint under the old bolt add in a new piece of pipe and put the release value on top this new piece of pipe at the same height/location.

Any suggestions/help greatly appreciated.

Chop the pipe just below the soldered joint. Put on new olive and compression nut. You've enough room there without adding pipe.

Its not a compression ring thats why you can't move it.

What you have is a soldered straight tap connector. There should have been a fiber washer (often red) on the flat face of what you thought was the olive.

No need to cut or remove anything!

Get a New Fibre Washer that fits snugly onto that fitting and then fit your new air vent straight onto it and tighten it up, job done.
