Waterless (“zero flush”) urinals are low-maintenance—not no-maintenance. A simple routine—cleaning correctly, checking the seal, changing inserts on schedule, and doing an occasional line check—keeps odors down, drains clear, and operating costs predictable. This checklist is tailored for schools, offices, airports, and stadiums using PurLeve®/ZeroFlush-style systems.
How Waterless Urinals Stay Odor-Free
Instead of water, these fixtures rely on a drain insert that seals the restroom from the sewer line. Your setup will use either a liquid odor barrier or a mechanical insert like PurLeve EnviroSeal™. Keep that seal healthy and use the right daily cleaner—that’s 90% of great results.
Daily: Clean the Right Way
- Use approved cleaners. Choose a non-abrasive, non-chlorine bathroom cleaner and a soft cloth or pad. Avoid acids, bleach, or scouring pads; they can damage the finish and shorten insert life.
- Wipe, don’t flood. Spray the bowl, wipe it down, and dry the rim and surrounding areas. Don’t pour buckets of water into the bowl; repeated flushing can displace the odor barrier in liquid systems.
- Mind the floor and grout. Many “urinal odors” actually come from the floor. Mop with an enzyme-friendly cleaner that breaks down urine crystals and dry the area.
Weekly: Quick Visual Checks
- Confirm the seal.
- Liquid systems: verify the odor barrier level using your insert key or sight line; top up or replace if low.
- EnviroSeal™ systems: ensure the insert is seated correctly and the seal mechanism moves freely.
- Look for clues. A sudden odor, unusual gurgle, or slower drain is your signal to check the insert and line before complaints pile up.
- Update the log. Note unit ID, date, and any observations. A wall-mounted service sheet keeps teams aligned across shifts.
Monthly: Light Preventive Care
- Test flow. Remove the insert and run a small volume of warm (not hot) water with a mild cleaner through the drain. You should see steady movement.
- Assess change cadence. Match insert changes to real traffic. If a restroom near a cafeteria or arena runs heavy, shorten the interval preemptively.
- Inspect splash zones. Check wall panels and partitions for buildup; clean and protect as needed to help overall odor control.
Change-Out Cadence (What to Plan For)
- Odor-Barrier Inserts: Many facilities replace inserts every 2–6 months depending on use (typical rating ~15,000 uses per insert). Busy venues may swap more often; moderate sites often land around twice per year.
- EnviroSeal™ Mechanical Inserts: Longer intervals because service is usage-based (often up to ~45,000 uses). Track traffic and performance, not just the calendar.
- Rule of thumb: if odors persist after a proper clean and the floor is fine, swap the insert first—it’s the fastest way to isolate an insert issue from a line issue.
Quarterly: Mini “Tune-Up”
- Do a full line check. With the insert removed, confirm flow and look for signs of partial blockage (slow movement, backwash).
- Standardize training. Five minutes with custodial staff on the right cleaner, the seal check, and the change-out process prevents most problems.
- Stock review. Ensure you have spare inserts (oil-barrier or EnviroSeal™), an insert key, and approved cleaners on hand.
Troubleshooting: Odor or Slow Drain
- Is the barrier/seal intact?
- Liquid systems: top up or replace if the level is low or displaced.
- Mechanical systems: reseat or replace if the insert is loose or worn.
- Is the floor the culprit? Clean grout and base thoroughly; dry the area.
- Is the line restricted? Remove the insert, run warm water with mild cleaner, and check flow. If slow, schedule a mechanical cleaning (snake/auger).
- Avoid harsh chemicals. Skip caustic drain openers—acids and lye can damage elastomers and inserts and don’t solve root or structural issues.
If symptoms persist after a fresh insert and floor clean, escalate to line cleaning or a quick inspection downstream.
Parts and Supplies to Keep on Hand
- Approved non-abrasive restroom cleaner and soft cloths/pads
- Insert key/tool for your model
- Odor-barrier packs or EnviroSeal™ kits (match your system)
- Service log (unit ID, date, insert type, notes on odor/flow)
- Optional: enzyme-friendly floor cleaner for grout and splash zones
Keep Your Waterless Urinals Running Smoothly
A little structure goes a long way. Clean with gentle products, confirm the seal weekly, change inserts on a usage-based schedule, and run a quick flow check each month. That’s it. Your fixtures will stay odor-free, staff time will stay predictable, and you’ll keep the water savings that made you switch in the first place.
