Just wanted to get some thoughts on this. I drove to College Station from Leander today to change the air filters at our rental properties and to address a "dishwasher won't drain" from one of our houses. Clogged pipe under the sink was stuffed full of pieces of plastic mainly. Not a huge deal but I had to take off the disposal and a few pipes. Anyways what's a fair number to charge the tenants for this? I'm guessing a plumber would charge around $300? I don't want to do it for nothing because then they will never learn that drain is not some magical hole anything can be stuffed down.
