Hotels and casinos with restaurants deal with many of the same drain issues that restaurants do.  However, most restaurants don\'t deal with hundreds of showers and toilets that are also contributing to the plumbing and sewer system of the facility.  Don\'t compound your plumbing issues by letting food, waste, and grease enter your pipes.  Hotels and casinos have also found Drain-Net\'s Lock and Stop^(TM) to be the perfect solution to securing their drains.
