1 in x 100 ft Pool Backwash Hose - Heavy Duty Reinforced PVC

In this review the 1 in x 100 ft pool backwash hose is evaluated for homeowners and pool service users who need a long, durable discharge line for draining and backwashing. The biggest reason to buy is the combination of a full 100 ft length and reinforced PVC construction with aluminum pin-lug fittings, which makes it practical for reaching distant drains and attaching directly to pumps and filter valves. The review focuses on build, ease of use, and real-world performance when paired with common pool pumps and sand filters.

Key Features

• Standard sizing: The hose uses a standard 1 in ID and a flat 1.8 in width so it threads to like-sized pump ports and most standard fittings without adapters.
• Full 100 ft length: A continuous 100 ft run lets users reach remote discharge points without splicing multiple hoses together.
• Reinforced construction: Molded PVC reinforced with polyester yarn and stainless clamps on the pin-lug fittings provides strength and resistance to bursting under typical working pressure.
• Aluminum fittings: Male and female 1 in aluminum connectors with pin lugs secure quickly to matching valve ports and pumps for a garden-hose style connection.
• All-season durability: The PVC is resistant to UV, abrasion, oils, grease, acids and alkali so it can be used outdoors across seasons with less material degradation.
• Low maintenance: The hose is easy to attach and detach, simplifying routine tasks like backwashing a sand filter or draining a pool.

Who It's For

The hose is well suited for homeowners with above- or in-ground pools who need a reliable long discharge line for backwashing sand filters, cleaning filters, or draining to a distant sewer or yard drain. It also fits pool service professionals who frequently connect to different pumps and valves and value a ready-to-use 100 ft hose that threads directly onto common 1 in ports.

Those who should look elsewhere include users needing a smaller coilable hose for tight storage or those requiring specialized quick-connect couplers not compatible with 1 in pin-lug or threaded fittings. If your installation consistently exceeds 90 psi working pressure or needs a larger diameter for reduced pressure loss, consider a higher-capacity hose.

Pros & Cons

Pros

• Long 100 ft length covers remote discharge points without extra joins.
• Sturdy reinforced PVC and stainless clamps reduce the risk of burst or leakage under normal use.
• Aluminum male and female 1 in connectors make hookup simple and familiar.
• Resistant to UV and common chemicals so it can stay outdoors season to season.

Cons

• Some users report occasional leakage around fittings, so clamps and proper seating should be checked before each use.
• The long length makes storage and rolling more cumbersome compared with shorter, more flexible hoses.
