WATERLESS URINAL MAINTENANCE

25 Apr 08

PREVENTIVE MAINTENANCE INSTRUCTIONS:

To keep the urinal, cartridge, and check valve working optimally, weekly remove the cartridge and check for any deposits on the end of the check valve and drain line. To remove the cartridge, insert the cartridge tool with handle, or a medium screwdriver into tee handle hole. The best way to get the cartridge out is to insert the tool, lock it in place, then rock the cartridge side to side to break it loose. Remove the cartridge by turning the tool while pulling up. NOTE: If the cartridge is in tight, put some liquid calcium dissolver around the outside edge and tap with plastic or rubber hammer if needed. Let sit for a few minutes and then remove the cartridge by turning the tool while pulling up. Be careful not to core out the center holes. If any deposits are observed, run the valve under water while massaging the valve end (do not remove the rubber valve as you will be unable to attach it again). Any accumulated deposits should come right off the valve. Check to ensure the curl on the end of the valve is maintained and there is a good seal. Flush the urinal housing with water to ensure there is good drainage, and then re-install the cartridge making sure to apply a rubber-safe lubricant to the gasket. Flush the drain lines with a bucket of water (2-3 gal.) 3 times a week by pouring water directly into the urinal without removing the cartridge. Pour approximately 4oz of “BUBA” (provided by government) down each urinal once a month. Flushing the cartridge with water or “BUBA” will not harm the check valve, but be cognizant of hard water deposits in the water, which can cause build-up. Be careful not to use urinal cakes, which can discolor the cartridge top over time and void the warranty.
