Hadley Air Horn
I need to remove and clean my Hadley air horn solenoid or replace it. Everything I have read says you have to drain the air tank first. Perhaps a dumb question, but how to you first drain the air tank...

It is a gasser, the only air tank is the one to the airhorns in the upper front of the unit. Horns do not work at all, which is why I need to remove and clean or replace the solenoid.
