r/DIY on Reddit: Safe underwater (fountain lights) low voltage splice?
December 16, 2019 -
I bought a property that included a 20+ year old fountain in the front yard. Within the fountain are 6 defunct underwater lights that are wired from the bottom of the concrete base, into PVC underground conduit back to a low-voltage 12V transformer. The only splice in the line is where the wires attach to the transformer. I've opened the lights to try and replace the bulbs, but the internal hardware is corroded and busted -- in other words, the lights themselves have to be replaced.
What I'm trying to determine is whether I can cut the line at the base of each light and splice in underwater 12V LED lights. If my only safe option is to replace the light and the whole wire to the transformer, I'll likely just leave them as is -- the trouble is not worth it. Is there a safe way to complete an underwater splice?

Use scotch 23 or 2155 rubber sealing tape. The surface has to be clean but this stuff will keep it dry forever. I've used it for fiber splices that were always getting flooded in their can. Lasted over 15 years underwater. Make sure you stretch it as you apply it. It will bond to itself permanently and has to be cut off later.
