Do you have a Maplins in your area? They sell heat-shrink tubing.

Another tip.  If you are joining a twin cable and don't want a "lump" in the joint, just stagger the two joints so that they are at least an inch apart.  Taping/heat-shrinking will then give you aless bulky joint.

I changed my pump last year. I crimped the wires together then smeared the connections with silicon sealant. Let it set then put it all back together. It worked a treat.

That may be OK if the wires are held in a position where they cannot move, or get knocked.  Silicone sealent is not a robust material for that kind of purpose, and a short circuit could be caused, unless you also wrapped insulating tape immediately around the individual wires to cover the bare sections.

I get your point gazza, but if it was me in that situation, I would renew the wiring completely so as to have no joint in a wet (immersed?) environment.

Taking on board your method of using sealant, if that was the only viable alternative, I would stagger the actual joints as I already stated and, after the sealant had set, use shrinkwrap sleeving to complete the job.

Not being critical, just offering my approach for anyone who may be interested. I tend to do repairs on the premise of fix and forget.
