Short answer: For a slow drip from the EverSweet Max 2’s front tray edge, PETKIT’s reply on the owner’s exact thread recommends checking the underside and edge of the water tray for scale or dirt and cleaning the tray. If the leak continues, PETKIT asks for the unit’s serial number so support can investigate. That is a limited first check, not a confirmed diagnosis. The owner did not say whether the fountain is the UVC or non-UVC version, so identify your variant and use its own care instructions.

Confirm which Max 2 you have

PETKIT lists EverSweet Max 2 and EverSweet Max 2 (UVC) separately on its manual-download page. The UVC product listing identifies a UVC wireless pump; the portal links separate documents for the two Max 2 versions. Check the product label, packaging, or PETKIT app/model details and open the matching instructions before removing parts. Do not assume pumps or variant-specific cleaning directions are interchangeable.

The owner’s question describes a drip at the front-left corner, where the tray area meets the lower container. The post does not identify the UVC variant. It also reports limescale buildup, but that observation does not establish what caused the leak.

Checks PETKIT supports

  1. Pause use if water is reaching the surface below. Keep the fountain away from a wet area while you inspect it, and provide another water bowl for your pet. If water reaches the wireless base or control module, stop using the fountain and contact PETKIT. The variant documents warn not to rinse or soak the base or control module; the UVC manual says repairs should be performed by professionals.
  2. Check the tray edge and underside. PETKIT’s official account replied in the owner’s thread: look for limescale or dirt on the bottom or edge of the water tray, then give the tray a thorough clean. This is the only leak-specific first check found in the public material. Follow the cleaning method in the manual for your exact variant; do not assume the two models have identical washing directions.
  3. Reinstall parts by the matching guide. The UVC manual shows the tray placed beneath the outlet and secured with its latch. Refit the parts in the order shown for your version; do not force the tray or latch. If you cannot seat a part as illustrated, stop and ask PETKIT rather than bending it or adding sealant.
  4. If you have the UVC model, check placement. Its manual says to keep the fountain on a level surface. This is a basic setup check; it does not show that an uneven surface caused a seam leak. For the non-UVC model, use its linked cleaning guide and ask PETKIT if you need instructions beyond it.
  5. Observe the result without guessing. If you continue only after the tray is clean, dry and correctly installed, watch for water at the same corner. Stop if it drips again or water is running toward the base. Do not keep topping up and testing a unit that is wetting the surface or electronics.

PETKIT’s official reply says to send the serial number if cleaning does not resolve the issue. Use PETKIT customer support and include the exact variant, a photo of the leak location, whether residue was present, and what happened after cleaning and reassembly. The EverSweet Max 2 (UVC) product page lists its tray and pump as separate components; this does not mean pump cleaning repairs a tray-to-container leak.

What the public instructions do not establish

PETKIT’s reply does not say that scale is definitely the cause, prescribe vinegar, explain a repair for a persistent seam leak, or recommend replacing the pump. The UVC manual and non-UVC cleaning guide cover routine care, while the UVC manual also shows assembly and level placement. Neither gives a repair procedure for a seam leak. Avoid glue, silicone, tape, disassembly of the base, or other improvised fixes. The UVC and non-UVC manuals have different variant labels, so check the exact document before cleaning or ordering a part.

Should I clean the pump too? The leak-specific reply asks you to inspect and clean the water tray’s underside or edge. It does not say pump cleaning fixes leakage at the tray seam.

Can I keep using it if the drip is small? If water is escaping onto the surface below, pause use while you contact PETKIT and offer another water bowl. If the base or control module is wet, stop using the unit.

What if cleaning does not help? Send PETKIT the serial number, variant, leak photo, and the steps completed. The public guidance does not explain how to repair or reseal the seam.

The owner post is one report, not evidence of prevalence or a model-wide defect. Checked October 16, 2026.
