1-1/4 in x 100 ft Pool Backwash Hose - Heavy Duty Reinforced Lay Flat

In this review we test the 1-1/4 in x 100 ft Pool Backwash Hose to see who should pick it and why. The bottom line: this hose is for homeowners, pool service pros, and anyone needing a long, reinforced discharge line that resists bursting and the elements. The strongest reason to buy is its extra heavy-duty construction with braided polyester reinforcement and thick walls that keep the hose intact under pressure and in outdoor conditions, making it a reliable choice for pool backwash, sump and trash pump discharge.

Key Features

• Size compatibility: The 1-1/4 in inside diameter and 1.98 in flat width fits standard 1-1/4 in hose adapters and many schedule 40/80 PVC pipes without adapters.
• Heavy-duty reinforcement: High tensile braided polyester fiber and thick walls provide burst resistance and long-term durability when routing discharge water.
• Weather and chemical resistance: The PVC construction stands up to outdoor exposure, chemicals, and seasonal use without degrading quickly.
• Included clamps for easy hookup: Each hose ships with two metal clamps so you can attach it directly to filter outlets, pumps, or PVC fittings and secure a leak-free connection.
• Wide use cases: Suitable for above ground pool drains, backwash lines, sewage and sump pumps, trash pumps, and sand filter discharge duties around homes and job sites.
• Leak and burst rating: Reinforced design prevents leaks or bursts up to the stated working pressure of 90 psi W. P., giving confidence under load.

Who It's For

This hose is aimed at pool owners who need a straightforward, robust discharge line for backwashing filters or draining above ground pools, and at contractors who move pump discharge between sites. Its length and reinforcement make it a good match when you need to route water away from patios or landscaping without frequent replacements.

It is less suited for systems that require larger than 2 in outside diameter fittings without adapters, or for users who need smaller-diameter precision hoses for low-flow filtration tasks. If you need a lower-profile garden hose or a flexible lightweight hose for regular watering, consider a different product.

Pros & Cons

Pros

• Sturdy reinforced construction offers clear durability and burst resistance.
• Comes with two metal clamps for a simple, secure connection out of the box.
• Works across many applications from pool backwash to sump and trash pumps.
• Resists weather and chemical exposure for seasonal outdoor use.

Cons

• Some users report mixed results with water flow depending on their setup, so fittings and elevation can affect performance.
• Fits up to 2 in outside diameter pipes without an adapter, so larger fittings need additional hardware.
