DAVCO 1.5" Pool Backwash Hose 50 ft — Reinforced Blue PVC Lay-Flat with Aluminum Pin-Lug Fittings

DAVCO's 1.5" ID × 50 ft pool backwash hose is a heavy-duty, reinforced blue PVC lay-flat discharge hose with aluminum pin-lug fittings for draining pools, backwashing filters, and connecting to pumps.

This hose combines a standard 1.5-inch interior diameter with a 50-foot length in a flexible, lay-flat design so you can move water from pool filters, sump pumps, trash pumps, and sand filters without fuss. Built with polyester reinforcement and stainless-steel clamps holding aluminum male/female pin-lug connectors, the hose resists common outdoor stresses and threads easily onto compatible pump ports.

How durable is this hose for regular pool backwashing?

The DAVCO backwash hose is designed for frequent use: it’s extruded from PVC, reinforced with polyester yarn, and secured by stainless-steel clamps to prevent leaks under typical working pressures. It is engineered to withstand abrasion and routine handling without bursting or stretching.

• 90 psi working pressure rating for dependable performance.
• Polyester-reinforced walls to resist kinks and tears.
• Stainless-steel clamps fixing aluminum pin-lug fittings to prevent leaks.
• Flat 2.6 inch width when collapsed for compact storage.

Will the connectors fit my pump and filter ports?

The hose comes with standard 1.5-inch male and female aluminum pin-lug fittings designed to match most 1.5-inch valve ports and pump threads. The metal connectors are installed to provide a snug, threaded connection similar to a garden hose, making setup straightforward for common pool equipment.

• 1.5" interior diameter fits standard 1.5" ports and fittings.
• Includes both male and female aluminum pin-lug connectors for adaptability.
• Threads directly onto pumps and filter valves—no special adapters in most cases.
• Clamped fittings reduce slippage during operation.

How does this hose perform in different weather and chemicals?

DAVCO formulated the hose to resist environmental and chemical stressors encountered around pools and outdoor pumps. The PVC construction offers resistance to UV, oils, grease, and moderate acid/alkali exposure so it can be used across seasons without rapid degradation.

• UV-resistant outer layer for prolonged sun exposure.
• Resistant to oils, grease, and common pool chemicals for extended life.
• Suitable for year-round outdoor use in most climates.
• Lay-flat design minimizes trip hazards and allows easy storage.

How easy is it to install, store, and maintain?

Installation is quick: simply match the 1.5-inch fittings, thread onto the pump or valve, and secure the connection. After use, the hose collapses flat for compact storage and cleans easily with water; routine inspection of clamps and fittings extends lifetime.

• Quick-thread aluminum pin-lug fittings for fast hookup.
• Lay-flat profile rolls or folds compactly for storage.
• Rinse and drain after use to prevent trapped debris.
• Check clamps periodically and tighten as needed for leak prevention.
