You can drain it by just removing the hose, never found an easy way to drain it any other way set up as from the factory. While you have it out, Summit sells some inline drain plugs that go into the lower hose. Not sure if this is the right size, but it's the kind of part you want.
Also, it does get easier if you lube the inside of the hose. Places sell dedicated lubes for it, I just normally use petrolium jelly.
