Urinal Blockages & Unblocking
Urinals typically become blocked due to a buildup of uric scale, which forms when urine proteins mix with hard water. Over time, this hard, chalky residue accumulates in urinal traps and pipework, narrowing or fully blocking the flow. Other factors such as insufficient flushing, debris, or paper towels can contribute to blockages. Blocked urinals not only cause inconvenience for staff and visitors but can also create malodours and hygiene concerns, potentially disrupting washroom operations in busy facilities. Regular maintenance and fast unblock solutions are essential to keep urinals functional and hygienic.
For urgent blockages, the fastest solution is to use a specialist chemical unblocker like URIC XTREME®. It is designed to dissolve uric scale quickly and safely, often clearing a blocked urinal in as little as two minutes. Simply pour the chemical into the trap and pipework, allow time for it to act, then flush thoroughly. Unlike mechanical plunging or manual removal, chemical unblockers require minimal effort, reduce disruption, and are safe on all standard urinal surfaces including stainless steel, plastics, and ceramics. Fast delivery ensures your facility can respond immediately to emergencies.
The safest and most effective method is to use a purpose-made chemical unblocker, such as URIC XTREME®. This product dissolves uric scale in just a few minutes, eliminating the need for risky mechanical tools or harsh acids that can damage pipework or surfaces. URIC XTREME® is non-corrosive, safe on stainless steel, plastics, and ceramics, and comes with full COSHH documentation for safe handling. It’s ideal for high-traffic facilities like schools, offices, and pubs, where hygiene and speed are priorities.
Using a specialist unblocker like URIC XTREME®, uric scale can begin dissolving within minutes. Full clearance often occurs in 2–10 minutes, depending on the severity of the build-up and the size of the blockage. For heavier or older scale, multiple applications may be necessary. Using a chemical unblocker is much faster and safer than manual or mechanical methods, which can be messy, time-consuming, and less effective. Regular maintenance can prevent scale from building up in the first place.
Yes. Blocked urinals can create unpleasant odours, attract bacteria, and compromise hygiene standards in washrooms. They may also require closure of the facility for cleaning, causing disruption for staff and visitors. In public or commercial environments, blocked urinals can also damage reputations and lead to complaints. Using specialist unblockers and regular preventive maintenance ensures facilities remain safe, hygienic, and fully operational.
Yes. Even with normal use and regular flushing, uric scale can accumulate over time due to the natural reaction of urine proteins with hard water. Factors such as infrequent deep cleaning or high-traffic usage can accelerate build-up. Preventive maintenance, such as URIC FREEFLO®, is essential to stop blockages before they occur and maintain washroom hygiene consistently.
The frequency of unblocking depends on traffic, water hardness, and cleaning routines. High-traffic areas may require intervention every few months if preventive maintenance isn’t used. Facilities using regular maintenance chemicals like URIC FREEFLO® experience far fewer blockages, reducing the need for emergency unblocking. Scheduling preventive maintenance is often more efficient and cost-effective than waiting for recurring blockages.
Urinal Maintenance and Blockage Prevention
Urinal maintenance involves regular treatment of urinal traps and pipework to prevent uric scale build-up. Without maintenance, uric scale gradually narrows or blocks the system, causing malodours, hygiene issues, and potential closures. Maintenance ensures urinals remain hygienic, odour-free, and fully operational, while reducing emergency call-outs, cleaning time, and costs. For high-traffic facilities, preventive maintenance is essential for consistent washroom performance.
Regular maintenance keeps uric scale from forming in traps and pipework. Chemicals such as URIC FREEFLO® break down the proteins and mineral deposits that cause blockages before they harden. Consistent treatment ensures that urine flows freely, odours are minimized, and facilities remain clean and hygienic. Regular preventive maintenance reduces the need for emergency unblocking and extends the lifespan of the urinal system.
The ideal frequency depends on traffic and water hardness, but most facilities benefit from weekly to monthly treatments. High-traffic areas may require more frequent dosing, while low-traffic sites can manage with longer intervals. Using URIC FREEFLO® subscription service ensures chemicals are delivered and applied consistently, maintaining protection without the need for manual reordering or tracking.

Chemassist’s URIC FREEFLO® is the primary product for preventive maintenance. It is safe, high-performance, and easy to use. URIC FREEFLO® can be applied manually or via automatic dosing systems, ensuring traps and pipework remain free of uric scale, reducing odours, and preventing blockages. It is suitable for all standard urinal surfaces including stainless steel, plastics, and ceramics.
Yes. Chemassist offers a subscription service that delivers URIC FREEFLO® at regular intervals, keeping urinals protected without manual ordering. Subscriptions can be customized to match traffic levels and dosing requirements, ensuring continuous maintenance, consistent hygiene, and reduced operational effort for facilities teams.
By preventing uric scale build-up, maintenance chemicals keep urinals flowing freely, minimizing stagnant urine and odour-causing bacteria. This creates a fresher, more hygienic environment for staff, visitors, and customers. Regular maintenance also reduces the risk of emergency closures and contributes to health and safety compliance in commercial and public facilities.
Yes. URIC FREEFLO® and other Chemassist maintenance products are non-corrosive and safe for all standard urinal surfaces, including stainless steel, plastics, and ceramics. They require minimal safety measures, making them easy for facilities staff to use without risk of damage or injury. Full COSHH documentation is provided to ensure safe handling.
Drain Cleaning & Other Products
Acid-based cleaners, such as sulfuric or hydrochloric acids, dissolve blockages quickly but can be corrosive and hazardous to both pipework and users. They require strict handling, protective equipment, and ventilation. Alkaline cleaners, like Chemassist’s ORPHEUS® products, are safer, non-corrosive alternatives that effectively break down grease, fats, and organic deposits. Alkaline cleaners are safe on stainless steel, plastics, and ceramics, easier to apply, and suitable for commercial kitchens, washrooms, and general drains. Choosing the right type depends on the blockage type, surface materials, and safety requirements.
Grease, fats, and oils accumulate in kitchen sinks and commercial drains, solidifying as they cool and forming sticky deposits. Over time, this narrows pipework, causing slow drainage or full blockages. Regular treatment with specialist chemicals or enzymatic cleaners helps prevent buildup, maintaining efficient flow and hygiene. Proper cleaning routines combined with chemical maintenance reduce emergency plumbing interventions and protect pipework from corrosion or damage.
Yes. Chemassist products are formulated for high performance and safety, including COSHH-compliant documentation. Alkaline cleaners are non-fuming, non-corrosive, and safe on all standard pipework. Acid-based products are provided only where necessary, with guidance for safe handling and storage. Facilities teams can use Chemassist products with confidence, maintaining drains efficiently without compromising safety or hygiene.
Absolutely. Regular use of specialist drain cleaning products helps remove buildup before it hardens, preventing recurring blockages. For example, consistent treatment of kitchen drains with grease and fat control products keeps pipes flowing, reduces odours, and minimizes costly emergency call-outs. Combining chemical treatment with proper hygiene and routine cleaning ensures long-term efficiency and drain protection.
