DAVCO 1.5in x 100 ft Pool Backwash Hose - Heavy Duty Reinforced

In this review the DAVCO 1.5in x 100 ft Pool Backwash Hose is evaluated for pool owners and maintenance pros who need a durable, reusable discharge line. The bottom line: this is a heavy duty reinforced PVC lay flat hose that stands out for strength and longevity, making it a practical choice when backwashing filters, draining pools, or running pump discharge. The review focuses on build, fit, multiuse capability and whether it delivers better value than thinner, single-layer alternatives.

Key Features

• Reinforced construction: The PVC body reinforced with polyester yarn delivers a robust hose that resists bursting and rough handling during repeated use.
• High working pressure: Rated to withstand about 90 psi working pressure so it can handle both supply and drainage tasks without deforming under normal pump loads.
• Standard connections: The 1.5in standard diameter and a flat 2.6in width make it compatible with 1.5in filter outlets, cam lock or pin lug fittings, and smaller schedule 40/80 PVC pipes.
• Multipurpose use: Designed for pool backwash and drainage, it also works well for irrigation, landscaping, construction dewatering and submersible pump discharge.
• Easy storage: The lay flat design rolls up compactly after use so it is simple to store out of sunlight when the season ends.
• Durability advantages: Unlike single-layer paper-thin hoses, this heavy-duty construction resists chemicals, weather and repeated rough handling.

Who It's For

The DAVCO backwash hose is best for homeowners with in-ground or large above-ground pools, pool service technicians, and anyone needing a rugged temporary discharge line for pumps. It suits users who want a hose that is reusable and more resistant to punctures than basic disposable hoses.

Those who should look elsewhere include buyers who require nonstandard connector sizes without adapters or those needing very low-pressure garden hoses; this product is focused on 1.5in filtration and pump connections rather than general household watering.

Pros & Cons

Pros

• Thick, reinforced PVC construction increases lifespan compared with paper-thin hoses.
• Compatible with common 1.5in filter outlets and cam lock fittings for straightforward installation.
• High working pressure tolerance and chemical/weather resistance make it reliable for repeated backwashing and pump discharge.

Cons

• Some users report fit is not perfectly tight with every filter outlet, so measuring and an extra clamp or adapter may be required.
