DERPIPE 3" x 25ft Lay-Flat Pool Backwash Hose — Reinforced PVC, 90 PSI Weatherproof Discharge with 2 Clamps

The DERPIPE 3" x 25ft lay-flat pool backwash hose is a reinforced, weatherproof PVC discharge hose designed for high-flow pool drainage, sump pumps, and general water transfer.

This durable lay-flat hose balances strength and flexibility so you can move large volumes of water quickly and store the hose compactly when it’s not in use. Built from thickened PVC reinforced with polyester fiber and UV stabilizers, the hose resists tears, abrasion, grease and seasonal weather exposure. It ships with two clamps for fast attachment to cam-and-groove fittings or standard 3" connections, and it packs flat to save space in sheds, garages or pool pump rooms.

How does the DERPIPE hose perform for pool backwash and drainage?

The hose delivers high flow rates suitable for backwashing pool filters, emptying portable pools, and moving pond water. Its 3" diameter and 25-foot length provide a balance of capacity and reach for most residential setups. Reinforcement maintains shape under pressure to prevent kinks and flow loss.

• 3" diameter for efficient high-volume discharge
• 25 feet of length for reach from pool to drainage area
• 90 PSI working pressure supports pump-driven flow
• Reinforced wall resists collapsing under suction or pressure

Will this hose survive outdoor exposure and seasonal use?

Yes — the PVC compound includes UV protectors and the polyester weave resists abrasion and tearing, allowing year-round use. The material tolerates a wide temperature range, so it remains flexible in cool weather and stable in summer heat. Proper storage in a cool, dry place will extend useful life.

• Temperature range: -5 to 65°C (23–147°F)
• Formulated for UV resistance to limit sun damage
• Abrasion- and grease-resistant outer layer for tough environments
• Collapsible design reduces weather-wear during storage

How do I connect and secure the hose to pumps or fittings?

The hose is sized for 3" standard fittings and can also be adapted to 2.5" PVC pipe if needed. Two metal clamps are included to lock the hose onto cam-and-groove couplers or threaded adapters. Tightening the clamps creates a reliable seal that minimizes leaks during suction or discharge operations.

• Included clamps for quick, secure attachment
• Fits 3" standard pumps and fittings; adaptable to 2.5" with proper adapters
• Strong wall resists slipping under pressure or vibration
• Easy to fold and roll for transport after disconnecting clamps

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

The hose collapses flat when not under pressure, making it simple to roll and stow without taking much space. That flat profile also simplifies coiling on reels or shelving in pool equipment closets. Regularly draining and drying the hose before storage reduces mold and prolongs service life.

• Lay-flat design folds into a narrow roll for minimal storage footprint
• Lightweight compared with rigid pipe alternatives
• Rolls neatly for transport or reel mounting
• Store dry and shaded to maximize lifespan

Who is this for? The DERPIPE 3" x 25ft lay-flat pool backwash hose is ideal for pool owners, pond keepers, landscapers and homeowners who need a robust, portable solution for moving water. It suits anyone who wants a blend of high flow capacity, weather resistance and easy storage: homeowners managing seasonal pool maintenance, contractors working temporary dewatering jobs, and cottage owners who need reliable pond or sump transfer lines. If you require a heavy-duty, flexible discharge hose with secure fittings and compact storage, this model meets those needs without unnecessary bulk.
