I see a submersible pool cover pump such as the following advertised, and I am puzzled with several questions.
The power cable will be going into a large pool of water. I assume that the power cable is sheathed with PVC. How can PVC withstand a few months in the open? Isn't there an inherent risk (certainty, in the long term) that it will develop minute cracks? If that happens, wouldn't it be inherently risky?
The pump is indicated to be 3 lbs. That seems to be a lot of load to put on a vinyl cover. Wouldn't that weight resting still for at least six months over one spot cause the pool cover vinyl underneath to stretch or even possibly rip?
