I do a lot of work with underwater systems, and honestly it's amazing how efficiently water degrades things. Our experience is that it's always wire that degrades first, then plastics of various kinds. | |
| Mar 13 at 4:29 | comment | added | jonathanjo | @AnalogKid yes I'd probably use a relay too. it all depends on how big the pumps are, whether they are mains, etc. This kind of set up is very flexible, you can make them very reliable, keep all the wires sealed, far from water. Sometimes we run vertical fishing line, tethered to the bottom, to keep the floats in a particular position, stop them snagging etc. | |
