Making a keggle and HLT out of some sankes (legal) thanks to all the posts on this forum. What I haven't been able to find are any uses for the valve and tube that I pulled out of the keg. Seems like a waste to trash em.
Hold onto them. If you every plan to use a sanke as a fermenter, an extra spear is nice to have with a bit cut off the bottom to avoid getting the trub.
