It is, inside a very basic bi-mental switch, which has to be within a certain distance of the motor to ensure that it can switch the motor off, if it overheats, I didn't think silicon would insulate against heat to that extent, but as I say, as I have five now, I should be ok anyway!

Re: Pump motor overload protection switch
If this switch is where I think it should be, inside the motor housing, then surely there should not be any water and if there is then the waterproofing of the switch is going to be the last of your worries?
If you do want it waterproofed then mount it and spray it with WD40? John.
Long ago when men cursed and beat the ground with sticks, it was called witchcraft. Today, it's called golf.
Mine lives in a plastic junction box, on top of the motor, where the wires come in to be connected to the feed. This is set underground, right next to the pool, the lid being part of the decking, so when people get out, or dive in , the water can go through it to the workings below. I queried this with the local installer (it was in when we brought, so not the company that installed the pool), and they said it was fine/normal, although if it REALLY rains, and the pool over flows, guess where it goes!!!??
No idea where you can get it from - RS maybe? We used to use it in the mob on aircraft circuitry to protect from the elements without taking away any functionality from the items protected..........we also used it on our boots - gives a mirror 'bulled' shine with minimum effort..........
Many thanks for that, there's an RS not far away! I was thinking of Adsil, but that evaporates with time, so I'll give this a go, though I may not try it on my boots, they're suede!
