Val-Pak push/pull & draining water

With all the recent rain, I need to drain some water out. I have an old Apollo (Val-Pak) push/pull valve and a DE filter. I know I can drain water by backflushing, but it appears there is another valve that might let me drain without losing DE.

The faucet in this picture is broken, but assuming I can repair it, is that what it's for?
