The 50-foot length and 1.5-inch diameter fit standard pool pumps and filters, while the included metal clamp and warm, easy-to-handle ends make installations faster and more reliable. Below we answer common buyer questions and list the concrete specs that matter for everyday use.

How does this hose stand up to high-pressure backwashing?

The hose is engineered with a circularly woven, braided polyester core that raises burst resistance and maintains shape under pressure. Thick 1.2mm walls and reinforced construction reduce bulging and splintering during backwash cycles, so it handles repeated high-flow, high-pressure discharges.

• 1.5" internal diameter for standard pump flows.
• 1.2mm wall thickness for extra durability.
• High-tensile braided polyester fiber reinforcement.
• Circular weave design resists deformation under pressure.

Will it resist pool chemicals and outdoor weather?

This hose uses a specially formulated compound to tolerate chlorine and common pool chemicals while maintaining flexibility across seasons. UV and weather resistance help prevent cracking and stiffening when left outdoors between uses.

• Chemical-resistant material suitable for regular pool maintenance.
• UV-stable formulation for outdoor storage and use.
• Remains flexible in hot and cold conditions.
• Designed for repeated seasonal cycles without rapid degradation.

Is it easy to connect and secure to pumps and filters?

Connections are simplified by the warm, pliable hose end and the included metal hose clamp for tight, leak-free attachment. The fiber-reinforced wall holds clamps securely in place, preventing slips and minimizing backflow risk when properly installed.

• Included metal hose clamp for immediate use.
• Warm hose end eases fitting onto fittings and pipes.
• Reinforced walls prevent clamp slippage and leaks.
• Recommended: place clamp near pipe edge and tighten firmly.

What applications and pool types does this hose work with?

The 1.5" x 50' size is a versatile option for above-ground and inground pools, hot tubs, and sump pumps. Its capacity and length are suitable for routine backwashing, full drains, partial draining, and emergency discharge tasks.

• Compatible with standard pool pumps and filters.
• Suitable for above-ground and inground pool draining.
• Useful for hot tubs, spas, and sump pump discharge.
• 50' length provides flexible routing away from pool areas.

If you want a reinforced hose that tolerates pool chemicals, resists weathering, fits standard pump fittings, and arrives ready to install with a clamp, the U.S. Pool Supply 1.5" x 50' Heavy-Duty Reinforced Backwash Hose is built for that job.
