No minerals here. Just very fine black silt. Good for potting soil. My original 1980 model 80 gallon water heater had the plastic valve. The nice plumbers broke it during installation and neglected to mention it. Never did drain it but I did have to replace both elements over the 20 some year life. If the tank is still sound (i have 120 psi natural water pressure from my spring up the hill) I want to hook it into my shop air supply after I fix the thirty year old compressor. Nothing seems to last.

Most have the cheap plastic valve and knob. It's made hard to grip to keep people from over tightening it. I don't drain water heaters anymore cause nothing comes out. If I want to flush it I take the lower heating element out and then I can get in with a stick tool and break up the minerals and suck them out with a shop vac. Oh and drain it when hot and then after empty open the inlet valve back up.

But it is alien to me. I have never seen the likes of this amazing brass what-ever-you-call-it-thingie before. Is is merely a screwdriver operated faucet? And if so why? Why would such a thing even exist? What is going on? Will Rod Serling step from behind the curtain? Here are some pictures I took while standing on my head and feeling a bit sick to my stomach. Sorry about the poor quality as I could not see what I was doing at all. It was point and hope time. It is past time to drain my water heater and I wonder if there may be a nasty gotcha associated with this bizarre brass manifestation of some form of engineering I am not familiar with. Klingon perhaps? Too brutal looking to be Romulan.
