Compression fitting. Pipe not pushed home into fitting

[flutterbye]

So about a month ago I had to redo some pipework around the HW tank. I made a stupid mistake of cutting one of the pipes too close to an ancient tank connector that I don't want to touch. So there is was just enough of the 22mm pipe coming out of the tank connector to allow me to push a compression fitting onto it with the pipe hitting the stop inside the fitting.

The mistake I made was not to allow space on the pipe for the nut ! Anyway, having done what I did, I put the nut on the pipe, then the olive and then screwed the fitting on and tightened.

There are no leaks and there is little physical pressure on the joint due to other pipe work around baring most of the load. The joint is horizontal.

Even after a month I'm still worried about this and find myself checking it all the time. The heating/hw has been going on and off throughout this month.

The question is should it be ok now to leave like that? Can I put my mind at rest? If not, would an end-feed go on better requiring less pipe than a compression?

Thanks in advance for any replies.

While pipes should be fully pushed into compression fittings before tightening you find plenty when stripping pipework that were never pushed fully in and never leaked. To be honest I cannot see how it would leak now assuming the olive was tightened onto the pipe and not just the lip of it.
An end feed joint needs almost as much pipe as a compression fitting. Also I cannot see you getting the olive off to remake the joint without disturbing your ancient connector.
I reckon your options are either to isolate and drain the tank, remove the ancient connector, cut the pipe and replace with new bit of joined pipe and new tank connector or simply leave it and dont spend the rest of your life worrying.

Should be fine if its still water tight now.

As long as the olive is sat square into the end of the fitting it will seal.
