Thank you, 2 things: Many machines have a steam wand Shut off valve at the top behind the wands making de pressurizing and draining completely unnecessary. Shouldn't it be possible to do a quick rejuvenate/tune up of food grade silicone grease without any new parts by bending removing the cotter pin and knob and lubing the threads and possibly disconnecting the pipe and adding some silicone grease into the pipe?
