Laundry tubs are very similar to the other sinks in your household. The main diffence being the amount of water they hold. Many times our customers have their washing machines discharging directly into their laundry tub. With a setup like that lint begins to build up in the line causing a blockage. Once the laundry tub line is clogged and a washing machine fully discharges you can end up with an overflowing laundry tub and a big mess. We routinely clear these laundry tub blockages within an hour with a rodding service.
