The Whirlpool WP213045 Tub To Pump Drain Hose directs water efficiently from the washer tub to the drain pump during the draining process. This replacement hose connects the tub outlet to the drain pump, providing a secure pathway for wastewater to travel out of the tub when the pump operates. Its proper routing and connection help maintain steady water flow and support effective draining between wash and spin cycles. A worn, cracked, clogged, or leaking hose can restrict drainage and contribute to water remaining in the tub. Replacing the hose can restore proper water movement and reduce the risk of leaks.
