No device should be left on if you're fiddling with it.  Turn off any and all electrical power to the pump and system at the breaker panel. You can also go to the base of the pump to make sure it's turned off. On a pool pump, this will be the strainer basket. If you're not working with a pool pump, use whatever fixture is closest to the water tank. Check all piping and fittings for any cracks,, or damage, especially if system was shut down over the winter. Check each drain plug to see if it needs re-tightening, and manually operate any valves. Ensure that all nuts, bolts and anchoring fasteners of the pumping system are in place and tightened properly. You should also inspect any safety guards, belts and pulleys that there might be. Flush the hose to remove any build-up and ensure you have clean water. Run water through it, keeping a constant stream for a few seconds before you shut it off. This is especially important for hoses that aren't routinely used or haven't been used yet this season. Many people choose to use their garden hose or their washing machine hose connected to their garden hose. However, if your garden hose contains lead, know that you shouldn't drink from it. If you're using this for a well, be sure you have a way of filtering the water before and after it's through the hose. This will keep pressure from building up. Watch your water pressure gauge to make sure all is going according to plan.
