Pool Filter Backwash Hose
Many counties require backwash water to be run to the sewer system (curb). These pool backwash and discharge hoses are flexible and durable and 50% thicker than other hoses. They lay flat for easy roll up when not in use. Use hose clamps (below) to connect the backwash/ discharge hose to your pool filter.
For pumps larger than 1hp, a 2" backwash hose is recommended, to prevent 'hose whip' from high flow rates, and erosion problems. 50 ft. sections of 2 inch backwash hose can be connected together with a short length of 2" pvc pipe and two hose clamps, for longer hose runs.
