Extending float switch wiring

[morleyz]

Is there a safe/reliable way to extend the wiring on a float switch where the splice would be submerged?

I would like to add float switches to my ATO and salt mix containers so I can get notifications when they're low, but both containers are taller than the wiring for the float switches I have laying around. I'm sure I can find some with longer leads, but why spend the money if I don't have to, but I also don't want the wiring corroding and leeching into the water.

Thanks.

Would the heat shrink tubing work? Just slide it over the splice and hit it with a lighter

Solder, put a dab of silicone on the connection then slide heat shrink tuning over it and heat it up. Water proof connection

Easy enough. Thanks.
