I got some corny kegs from homebrewing.org. I took off the poppet valves to clean them. I believe most of the nylon washers in there are broken. The kegs arrived sealed, but are the broken washers going to cause leaks? I didn't see where I could procure new ones.
I just picked up some used cornies from Craig's List and replaced all the gaskets. All the gaskets for two kegs cost like $5 I think. It only took about 5 minutes to disassemble the kegs, install the new gaskets, and then reassemble everything.
Brewing beer is a fun and rewarding hobby. When you do good, you get beer. When you do bad, you get beer.
It's a lot like recreation league softball.
