I live in Massachusetts near Boston. Our bathroom sink has been clogged for about a month and a half. We cannot use it because within 30 seconds of letting the water run the sink is filled with water that won't drain. Building maintenance says the pipes are FULL of dirt. Around the same time the water pressure in our kitchen sink pretty much cut in half. It's nearly impossible to get dishes clean. Our landlord still hasn't had an actual plumber come by. Like I said. It's been about a month and a half. What should we do?
