that regard whether you switch one or both. But you do want to switch
both off if you ever need to service anything as if only one leg is
switched off, the other will be live with respect to ground, therefore
possible hazard.
Agree. I'd have to go look to make sure I'm remembering correctly, but I'm pretty sure on the one here there are double-pole contacts on the pressure switch -- all that would be required in that case would be to land the other side there as well to provide a total break to the pump.
But, in the situation it wouldn't help too much if it floods in an accident scenario like described above anyway--the hot side would still be submerged. Maybe not a dead short, but not something you'd want to just stick your hand into...
I'd be looking to move the switch as another person said when it warmed up I think--either on a riser to get it above the potential flood line or remote.
