I am using a submersible water pump whose plug has only 2 prongs. I'm assuming the third 'ground' prong is missing. I also doubt if there is any fuse or circuit breaker inside it as it is an absolutely cheap and unmarked pump.
I want to use it to supply a garden hose which involves putting the pump in a bucket full of water. The elaborate system which I plan to use involves a whole network of PVC pipes which is connected to this hose.
Can anything go wrong or can a fault develop after lots of use which can give me a shock?
Also what precautions must I take?
