Learn how to clean and maintain the PETKIT EverSweet 3 Pro UVC pet water fountain. Step-by-step instructions for keeping the UVC sterilization and filtration working well.
Quick Answer
To keep your PETKIT EverSweet 3 Pro UVC fountain safe and efficient, clean it every two weeks and replace the filter according to the schedule. Focus on the UVC pump and multi-stage filter to maintain water quality.
Why Regular Cleaning Matters
The EverSweet 3 Pro UVC uses a UVC light water sterilization pump and a 4-stage filtration system. Over time, pet hair, food debris, and mineral deposits can build up and reduce the effectiveness of both the UVC light and the filter. Regular cleaning prevents biofilm and keeps the water fresh.
The UVC sterilization works best when the pump and chamber are free of buildup. If you skip cleaning, the UVC light may not fully penetrate the water, and the filter can clog faster. This means you might need to replace filters more often than the recommended schedule.
What to Avoid During Cleaning
Do not use harsh chemical cleaners or bleach on any part of the fountain. These can leave residues that are unsafe for your pet and may damage the UVC lamp or plastic components. Use warm water and a soft cloth or the included cleaning brush.
The wireless pump is safe to submerge, but avoid pulling on the cord or submerging the power adapter. Always unplug the fountain before cleaning to prevent electrical hazards.
Step-by-Step Cleaning and Maintenance
- Unplug and Disassemble: Unplug the fountain from the power source. Remove the top cover, water tank, and any other removable parts. Set aside the filter and the pump. Always unplug before touching the pump or UVC components.
- Rinse and Scrub: Rinse all non-electrical parts under warm running water. Use a soft brush or cloth to gently remove debris from the tank, cover, and water channels. Do not use soap or harsh cleaners. Avoid soap residue—it can harm your pet and reduce UVC effectiveness.
- Clean the Pump and UVC Chamber: Following the manual, carefully remove the pump. Rinse it under warm water and use a soft brush to clean the intake and the UVC chamber area. Do not submerge the pump's electrical contacts. Check the pump for hair or debris that might block water flow.
- Replace or Rinse the Filter: If the filter is due for replacement, swap it with a new one. If it is still within its lifespan, rinse it under running water to remove loose particles. Do not scrub the filter media. Mark your calendar to replace the filter on schedule—don't wait for it to look dirty.
- Reassemble and Refill: Dry all parts with a clean cloth. Reassemble the fountain, insert the filter, and refill with fresh water. Plug the fountain back in and run it for a few minutes to confirm the pump works and the UVC light activates. Check for any leaks or unusual noise after reassembly.
