Quick answer
To replace the filter on a Petmate Replendish Waterer, remove the old cap, rinse the reservoir, and snap on the new Petmate Replendish Replacement Filter Cap. This keeps the water free of debris and maintains healthy hydration for your pet.
Why regular filter replacement matters
The filter cap traps hair, food particles, and sediment before they enter your pet's drinking water. Over time, the filter material becomes clogged and less effective. Replacing it every 2-4 weeks, or sooner if you notice reduced water flow, ensures your pet always has clean water.
Neglecting replacement can lead to bacterial growth in the reservoir and unpleasant odors. The cap is designed specifically for the Replendish system, so using a generic filter may not seal properly or fit the waterer.
Choosing the right replacement cap
The Petmate Replendish Replacement Filter Cap is available for X-Small (1/2 gallon) and Small (1 gallon) waterers. The cap measures 3 1/4 inches square, so it fits both sizes. Always check your waterer's capacity before ordering to ensure compatibility.
The cap is black and sold individually. Buying a spare allows you to have one ready when the current filter needs replacing.
Step-by-step replacement instructions
- Remove the old filter cap: Lift the waterer's lid and pull the used filter cap straight up from the reservoir. Discard the old cap. If it's stuck, gently twist while pulling. Common mistake: pulling at an angle can break the cap's tabs. Always lift straight up.
- Rinse the reservoir: Empty any remaining water from the reservoir. Wash the inside with warm soapy water, then rinse thoroughly to remove soap residue. Dry the rim where the cap sits. Checkpoint: soap residue can cause foaming in the water. Rinse until no suds remain.
- Install the new filter cap: Take the new Petmate Replendish Replacement Filter Cap and align it with the opening in the reservoir. Press down firmly until it snaps into place. The cap should sit flush and not wobble. Common mistake: pressing only one side can leave the cap loose. Apply even pressure around the edges.
- Refill and reassemble: Fill the reservoir with fresh water, replace the lid, and plug the waterer back in. Check that water flows freely from the spout. If not, recheck the cap installation. Checkpoint: after refilling, monitor for leaks around the cap for the first hour.
