Advice on damaged network fibre conduit.

Hi Sparkies

I have hit a fibre network conduit in the garden but luckily the fibre isn't damaged. There is an old, redundant copper landline cable in there that I damaged.

My question is, can I patch the PVC pipe and walk away leaving some residual moisture trapped Inside? Or will the whole section need replacing and sealed up?

I have opened a support ticket with the provider and awaiting the official report on repairs.
