How to repair damaged sump pump wire?

Hello all,

The exterior rubber insulation of the sump pump has been damaged.

The internal white linear and wire plastic wrap are perfect. Is there a way that I can repair this damage and prevent any water from leaking into the wire?

Thank you

You could use liquid electrical "tape" and coat the damaged area (carefully trim/remove the damaged insulation first). Heat shrink tubing would also work, but needs to be fished onto the end of the cable and slid over the damaged area. I seem to remember reading somewhere that heat shrink can be sliced and wrapped around a cable then heated. I believe you would need to used a high strength/high temp glue to med the ends first though.

You can get heat shrink tape.

That liquid tape would probably work but I'd leave the flap on. Fill that hole with the liquid, fold the flap over and cover with a wrap of black tape. You could use silicone adhesive in place of the liquid tape.
