I moved into my current house 5 years ago and had a couple of outdoor connections fitted throughout the garden. I have never tried to do anything with them until now. As I open a junction box to add a new wiring I see this:
The box has a tiny hole, which I guess is where the gel was filled from.
I would like confirmation that I need to remove (very sticky) gel from the box, install a new connection and buy some gel to refill it. Is this the case?
