DAVCO 1in x 25 ft Pool Backwash Hose — Blue Reinforced PVC with Aluminum Pin-Lug Fittings, 90 PSI

The DAVCO 1" ID x 25 ft pool backwash hose is a heavy-duty, reinforced blue PVC lay-flat discharge hose with aluminum pin-lug fittings designed for draining pools and connecting to pumps and filters.

This durable discharge hose is built for seasonal outdoor use, offering a standard 1" inner diameter, a flattened 1.8" width when laid flat, and a 25-foot length that fits most pumps and filter ports. Reinforced with polyester yarn and secured by stainless-steel clamps on the aluminum pin-lug fittings, it balances flexibility for storage with the strength needed for up to 90 psi working pressure. The hose resists UV, abrasion, oils, and chemicals commonly found around pool equipment, making it a reliable choice for pool maintenance, sump and trash pumps, and filter backwash.

How will this hose connect to my pump or pool filter?

The DAVCO hose uses standard 1" male and female aluminum pin-lug connectors that thread directly onto compatible pump outlets and valve ports, similar to garden-hose-style attachments. The metal fittings are fixed by stainless clamps so the connection stays secure during operation.

• Standard 1" ID and 1" pin-lug fittings for wide compatibility
• Thread-on installation — no special adapters for matching 1" ports
• Stainless-steel clamps keep fittings tight under pressure

Is this hose strong enough to avoid leaks and bursts?

Yes — the hose body is extrusion-molded PVC reinforced with polyester yarn, and the pin-lug fittings are clamped securely to prevent separation. It is rated to handle typical backwash and pump discharge pressures up to its 90 psi working limit when connected correctly.

• Polyester yarn reinforcement reduces stretching and kinking
• Extruded PVC construction resists cracks and abrasions
• 90 psi working pressure rating when properly installed

How easy is it to use and store the lay-flat design?

The lay-flat profile collapses for compact storage and reels easily onto a hose reel, while still lying flat under flow to maximize water discharge. Thread it onto a compatible pump or valve, run the hose to your discharge point, and the hose will flatten as it fills for efficient water flow.

• Flat 1.8" width when laid flat for compact storage
• Rolls or reels up quickly to save space in an equipment shed
• Lightweight compared to rigid discharge piping for easier handling

Can this hose handle outdoor conditions and chemicals?

The DAVCO discharge hose is formulated to resist UV exposure, abrasion, oils, grease, and moderate acid/alkali contact, so it stands up to typical poolside environments and seasonal changes. While built for durability, avoid prolonged exposure to extreme chemicals beyond normal pool maintenance products.

• UV and abrasion-resistant PVC outer layer
• Resists oils, grease, and common pool maintenance chemicals
• Suitable for year-round outdoor use in most climates

Who is this for: Pool owners, service technicians, and homeowners who need a reliable, easy-to-store discharge hose for backwashing filters, draining pools, and connecting portable pumps. It’s also a practical choice for sump, trash, and sand-filter pump setups where a reinforced, standard-size lay-flat hose and durable metal fittings are required.
