3 in x 100 ft Blue Backwash Hose for Swimming Pools - Heavy Duty Drain

In this review of the 3 in x 100 ft Blue Backwash Hose, the bottom line is simple: this is a workhorse hose for anyone who needs a long, heavy-duty discharge line for pool backwash and draining. The reviewer found it most useful for routine pool pump and filter waste tasks because of its length, reinforced construction and decent working pressure. It is not a precision-fit hose for every adapter situation, but for general water transfer and seasonal pool maintenance it delivers reliable performance and easy storage.

Key Features

• 3 in Diameter: The 3 in bore provides strong flow capacity for backwash and discharge, reducing time spent draining or transferring water.
• 100 ft Length: A full 100 ft of hose gives flexibility to reach distant drains or runoffs without adding extra connectors.
• 90 PSI Working Pressure: Industrial-grade pressure tolerance supports heavy use with common pool pumps and backwash setups.
• PVC with 3-ply Reinforcement: The PVC outer and 3-ply polyester yarn reinforcement resist abrasions and reduce the chance of leaks or tears during handling.
• Wide Temperature Range: Rated from 23F to 149F (-5C to 65C) so it can be used seasonally and stored without immediate material failure.
• Easy to Store: The lay-flat design rolls up neatly for off-season storage in a dry place out of direct sunlight.

Who It's For

This hose is aimed at pool owners, maintenance professionals and property managers who need a long, sturdy discharge hose for in-ground or above-ground pool backwash and draining. Its heavy-duty construction and 3 in diameter suit larger pumps and situations where high flow and abrasion resistance matter.

Those who require an exact fit to a 1 1/2 in or other smaller threaded outlet should look elsewhere or plan to use an appropriate adapter, since several users reported fit issues when trying to connect to smaller pipe sizes. Also, if seam thickness uniformity is critical, some buyers noted variability in thickness.

Pros & Cons

Pros

• Durable PVC and polyester reinforcement make it resistant to wear and chemical exposure in pool environments.
• The 100 ft length and 3 in diameter reduce the need for multiple hoses or connectors when routing to distant drains.
• High working pressure and wide temperature tolerance make it suitable for seasonal and professional use.
• Lay-flat design stores compactly after use for convenient off-season storage.

Cons

• May not fit smaller outlets without adapters; customers reported size mismatch with 1 1/2 in pipes.
• Some variability in thickness and occasional seam issues have been reported, so inspection before heavy use is advised.

Frequently Asked Questions

Will this hose fit a 1 1/2 in pump outlet?
It is designed for a 3 in diameter; for a 1 1/2 in outlet an adapter or a different hose size is required because customers have reported fit issues.

Can it be left outside in cold weather?
The hose is rated to 23F (-5C) but long-term exposure to freezing conditions and direct sunlight is not recommended; store in a dry place out of direct sunlight when not in use.

Is the hose resistant to pool chemicals and abrasion?
Yes, the PVC construction with 3-ply polyester reinforcement is built to resist chemicals and abrasions common in pool maintenance.
