Eastrans 3″ X 50′ Blue Backwash Hose
Premium flat discharge hose built for pool water systems with a flexible PVC core and reinforced polyester yarn. The 3″ diameter supports steady flow under typical backwash pressures, with a working pressure around 90 PSI. Temperature tolerance spans from 23°F to 149°F, suitable for in-ground and above-ground pool equipment. Aluminum camlock fittings help prevent oxidation and rust, maintaining a long service life in outdoor environments. This model emphasizes chemical resistance to oils, greases, acids, and common pool chemicals, reducing the risk of leaks and tears.
IMOLI 3” Discharge Hose Kit
This pump kit combines 20 feet of suction hose and 65 feet of discharge hose, designed for quick and tool-free setup. It features heavy-duty aluminum camlock C and E fittings to resist oxidation and corrosion, and a maximum working pressure of 90 PSI. The kit includes clearly labeled, ready-to-connect components that simplify installation. A built-in heavy-duty plated carbon steel filter protects pumps from debris, which helps reduce clogs and wear, extending equipment life in demanding environments.
USTAR 3″ x 100 Ft Backwash Hose
USTAR offers a heavy-duty, three-layer PVC lay-flat design that emphasizes durability and leak resistance. The outer PVC braid provides strength, the middle layer adds explosion-proof integrity, and the inner lining handles high pressure. This hose remains flexible under extreme temperatures from -5°C to 50°C and stays UV resistant, ensuring year-round performance. The 100-foot length supports extended backwash runs, and the hose remains relatively lightweight for easier handling and storage.
Eastrans 3″ x 100′ Backwash Hose
This longer version of the Eastrans backwash hose increases reach for larger pools or complex drainage layouts. It maintains the same robust 90 PSI working pressure and broad temperature tolerance. The 3″ diameter supports steady discharge volumes, while aluminum camlock C and E fittings prevent rust and corrosion. The reinforced PVC construction with polyester yarn minimizes leaks and tears, making it a practical choice for frequent backwash cycles and seasonal pool maintenance.
DERPIPE Lay-Flat 3″ x 25 Ft Backwash Hose
DERPIPE provides a 3-inch, 25-foot lay-flat hose engineered for weather resistance and durability. It includes clamps and is designed to connect easily to cam-and-groove fittings. The hose is rated at 90 PSI and operates effectively in temperatures from 23°F to 147°F (-5°C to 65°C). It’s built to resist oils, grease, and common pool chemicals, making it suitable for backwashing and draining tasks in smaller or space-constrained setups.
Buying Guide: Key Considerations for 3″ PVC Discharge Hoses
- Hose construction and materials: Look for reinforced PVC with polyester yarn and a heavy-duty outer coating to minimize leaks, tearing, and wear from chemical exposure.
- Fittings and compatibility: Camlock and pin-lug fittings are common; ensure fittings are corrosion-resistant and compatible with your pump and intake components.
- Pressure rating and temperature range: A working pressure around 90 PSI is typical; verify temperature tolerance aligns with your local climate and pool chemistry.
- Length and portability: Longer hoses reduce the need for connectors but add weight; consider a balance based on your pool size and setup.
- UV and weather resistance: Outdoor exposure requires UV-stabilized materials that won’t become brittle in sunlight.
- Storage and handling: Lay-flat designs save space and simplify storage; consider collapsible or roll-up options for easy transport.
- Debris protection: Integrated filters or compatible strainers help protect pumps from debris and extend life.
- Maintenance and ease of setup: Tool-free connections and clearly labeled parts save time and reduce installation errors.
- Application scope: Choose hoses suitable for backwashing, draining, or general pool water transfer to match your routine maintenance needs.
- Warranty and support: Consider brands offering robust customer support and clear warranty terms for pool equipment.
