Learn how to set up and maintain a gravity waterer like the Petmate Replendish to ensure your pet always has fresh, filtered water without electricity or constant refills.
Quick answer
Using a gravity waterer is simple: fill the reservoir, attach the base with the activated carbon filter in place, and let gravity refill the bowl as your pet drinks. Regular cleaning and filter changes keep the water fresh.
Why choose a gravity waterer over an electric fountain?
A gravity waterer like the Petmate Replendish delivers filtered water without needing a power outlet or pump. This makes it ideal for homes where you want a quiet, low-maintenance solution or for travel use. The trade-off is that it doesn't circulate water like a fountain, so you need to clean the bowl more often to prevent stagnation.
Step-by-step: How to set up and maintain your gravity waterer
- 1. Unpack and wash all parts: Separate the reservoir, base, and filter. Wash them with warm, soapy water, then rinse thoroughly. Do not put the filter in the dishwasher. Residue from manufacturing can affect water taste; a clean start is important.
- 2. Install the activated carbon filter: Place the filter into the designated slot in the base, usually near the water outlet. Ensure it sits flat and secure. Some models require you to soak the filter in water for a few minutes first—check the manual. A loose or dry filter may not filter effectively and can let debris pass through.
- 3. Fill the reservoir and attach the base: Fill the reservoir with fresh tap or filtered water. Invert the base and press it onto the reservoir until it clicks or seals. Then flip the entire unit right-side up and place it on a flat surface. If the seal isn't tight, water may leak or the gravity refill may not work properly.
- 4. Check the water flow: The bowl should fill automatically as the water level drops. If no water appears, tilt the unit slightly to break any air lock, or ensure the reservoir cap is vented (if applicable). An air lock is the most common startup issue; tilting usually fixes it.
- 5. Clean and replace the filter regularly: Every week, empty the reservoir and bowl, wash all parts, and replace the filter every 4-6 weeks or as recommended. Do not let old filters clog or grow bacteria. Skipping filter changes reduces water quality and can make the water taste stale, discouraging your pet from drinking.
