I too have had the same problems with clogged drains. I agree that the two biggest culprits are clay and acrylic paint (that is besides the kids who intentionally try to clog the drains!) I've also had to remove a trap from under a sink, trying to unclog it, only to find several missing paint brushes. I use what I call a "sludge bucket" for clay solids and thick slip -- having the kids to dump their water/slip mixtures into the bucket, rather than pouring them down the sink. Of course, every so often we have to empty the buckets outside, or at least pour the water off the top. I also do my best to have kids clean any solids or semi-solids out of their paint containers before washing them in the sink, but, of course, I'm not always successful at doing that.
