WaterWarden Inground Pool Safety Cover 18ft x 40ft - Strong Mesh

In this review the WaterWarden Inground Pool Safety Cover 18' x 40' is evaluated for homeowners who need a reliable, debris-blocking safety solution for an inground rectangular pool. The bottom line: this cover is best for those who want a robust, UL classified mesh that balances strength and water drainage, with hardware included and a long 15-year warranty providing confidence in long-term protection. It stands out for its thick polypropylene weave and reinforced strapping that promise heavy-duty performance without trapping rainwater.

Key Features

• Thick polypropylene construction: The heavy mesh material offers a break-strength over 4,000 lbs, giving solid resistance against accidental loads and large debris.
• Triple-stitched 2-ply strapping: Reinforced straps with manual X-tacking and non-corrosive aluminum tips increase seam durability where stress is concentrated.
• Abrasion-resistant pads: Protective pads at deck contact points reduce wear and extend the life of the cover at high-friction areas.
• Hardware included: The package contains a tamping tool, installation rod, hex key and solid brass anchors that recess flush to the deck for a safer, neater installation.
• UL classified to ASTM F1346: Certification to this standard and a 15-year warranty provide measurable assurance that the cover meets safety and quality requirements.
• Mesh allows drainage: Fine mesh permits rain to seep through while keeping out leaves, twigs and larger debris, preventing water accumulation on top.

Who It's For

This cover is ideal for homeowners with a rectangular inground pool sized 18 ft by 40 ft who want a safety-oriented solution that still allows rainwater to pass through. It suits families who prioritize certified safety and a durable build, and those who appreciate included installation hardware and anchors that sit flush when not in use.

It may be less suitable for buyers who need a solid, waterproof winter cover or who expect minimal maintenance of accumulated fine debris, since mesh allows water and fine particles to pass through. Also, customers seeking ultra-lightweight covers might find this model heavier due to its thick construction.

Pros & Cons

Pros

• High break-strength and thick material give strong protection against accidental loads.
• Triple-stitched 2-ply strapping and X-tacking enhance seam strength where it matters most.
• Included hardware and flush solid brass anchors simplify installation and reduce trip hazards.
• UL classification to ASTM F1346 and a 15-year warranty provide reassurance about quality and safety.

Cons

• Some customers report occasional seam or spring issues, so long-term durability can vary in practice.
• Mesh lets rain through, so it does not prevent water from entering the pool.
