How vital are inserts with pushfit plumbing with 22m acorn pipe?

I just did a very awkward plumbing job under my floorboards: I
installed two push-fit stopcocks in the main send and return of my
central heating system. After doing the job I realised I had forgotten
to use the stainless steel pipe inserts in the ends of the 22mm Acorn
pipes that went into the stopcocks.

The joints are not leaking at present, but are they likely to become
leaky in future? How vital is it that I take the floorboards up again
and redo the joints with inserts in the pipe-ends?


I don't know Acorn pipe, but if it is plastic (barrier or not), then you
need to redo it with inserts. If you don't, it will eventually leak. How
long it lasts depends on whether there is any mechanical load on the
pipe/fitting.
