They are using ..... wait for it.... PEPPERCORNS!!! Isn't that just about as clever an idea you have heard today?
And it was a drain that was frozen. AND it turns out it wasn't actually frozen. It turns out that the person who washes dishes around here doesn't believe in hot water and it was a grease clog in one of the main lines underground. (He [the dishwasher person] had to snake it out and was quite cigrined when the problem was determined)
Lol I was wondering how you had a drain line freeze. Kind of hard to do since they don't normally hold much water in them. I just had to unclog grease from our trap under sink the other day. Since then we have taken to drinking grease from hamburger for tacos into a colander sitting in a 9 inch round cake pan. We was using hot water running down drain and then just draining meat in the sink .
