The Power of BlueSeal: How This Trap Seal Liquid Transforms Waterless Urinals
In an earlier post, we discussed how the EcoTrap cartridge—an essential component of every waterless urinal—must be filled with BlueSeal two or more times per year. But what exactly is BlueSeal, and why is it so important for maintaining a clean, odor-free restroom?
BlueSeal is a high-performance, biodegradable liquid trap sealant developed by Waterless Co., Inc. Its advanced formula is designed to prevent unwanted odors from escaping the urinal drain, while supporting efficient, sustainable restroom operation. By understanding how BlueSeal works, facility managers can enhance restroom hygiene, reduce maintenance costs, and achieve measurable water savings.
How BlueSeal Works
1. Trap Seal Barrier
BlueSeal’s specific gravity is lower than that of water or urine, allowing it to float on top of the liquid inside the urinal trap. This creates an effective odor-blocking barrier that prevents sewer gases from entering the restroom.
2. Reliable Odor Control
Because the seal stops odors without flushing, waterless urinals stay fresh and hygienic even with heavy use. The biodegradable formulation maintains performance over thousands of uses.
3. Temperature Durability
BlueSeal remains stable in extreme conditions—non-evaporating up to 100°F and freeze-resistant down to -70°F—making it ideal for facilities in both hot and cold climates.
4. Eco-Friendly and Biodegradable
Unlike chemical-based alternatives, BlueSeal breaks down naturally over time, minimizing environmental impact and supporting green building goals such as LEED certification.
5. Simple Maintenance
Each refill uses about 3 ounces of BlueSeal, measured precisely with a PortionAid dispenser. It is compatible with standard cleaning solutions, so no special products or extra maintenance steps are required.
Benefits for Facilities
Water Savings: Enables true zero-flush urinal operation, conserving thousands of gallons per fixture each year.
Cost Efficiency: Reduces plumbing and winterization costs over traditional flush systems.
Ease of Use: Quick refills and low maintenance ensure consistent performance.
Extended EcoTrap® Life: Helps maintain trap efficiency for up to 7,000 uses per cartridge.
Improved Sustainability: Supports facility-wide water reduction and environmental compliance goals.
Comparing Waterless and Traditional Urinals
Water Use
Zero water; BlueSeal seals trap odors
1–3 gallons per flush; thousands wasted yearly
Odor Control
Biodegradable BlueSeal creates floating odor barrier
Depends on flushing; odors reappear if flush fails
Maintenance
Simple 3 oz BlueSeal refill; no valves
Requires pipe and valve repairs; seasonal maintenance
Cartridge/Seal Life
EcoTrap cartridge lasts ~7,000 uses
Flush parts wear faster; frequent replacements
Installation
No water lines or flush valves
Requires plumbing and water supply
Costs
Lower long-term expenses; only BlueSeal refills needed
Higher water bills and plumbing costs
Environmental Impact
Saves thousands of gallons per year; biodegradable
High water consumption and footprint
Key Takeaway
BlueSeal is the essential component that makes no-flush urinals efficient, hygienic, and sustainable. For facility managers seeking to reduce costs, prevent odors, and boost restroom sustainability, Waterless BlueSeal delivers measurable performance and environmental benefits.
