Does anyone know where I can get a float switch from here in the UK? I have a 6ft x 2ft x 2ft tank with sump and I would like to fit a float switch so if the inlet pipe to sump gets blocked the switch will turn pump off when water level drops.
The other problem is that all the float switches I've found work on low voltage but my pump plugs straight into mains at 240v. Does anyone have any ideas to help me???
What with self destructing heaters, gurgling overflows and the threat of flooding I'm close to giving up!!
