ok, I give up. The postmix machine has been sitting on the counter since last october, and I still haven't gotten around to hooking it up. In the time since, I'm pretty sure mice have chewed on some of the hoses, many of which probably needed replacing anyway, and even more of which surely do now.
Anybody want to come over, clean the thing out, replace whatever needs replacing, figure out the plumbing situation, install the lines, the filter, etc, in exchange for money? I want to just not think about it, I just want it taken care of.
