Unless your pool is sitting way low you should at least be able to get a gravity flow drain going using a couple garden hoses. Run the water from the garden hose into the pool and run another garden hose out the pool. Get a flow going into the hose leaving the pool for 20 seconds and then the flow should continue. Also you can always use your filter pump but not through your usual vacuum setup through the skimmer. If you submerge the hose that usually goes to the skimmer under water you can pump water out of your pool for ever with your return line going to where you want to drain!
