Voltage Setting and Power Cord Length
Check out the voltage requirements and the power cord length of the pump. The cord length needs to be checked out, as you need to ensure that the pump is close to the GFCI (ground fault circuit interrupter) outlet, which will supply it with power. In case you need to operate the pump 24x7, look for battery backup facility which lets the pump operate uninterrupted, even in case of power failures.
