When Your Gravity Waterer Needs a New Cap
The cap (or plunger cap) on a gravity waterer is the part that seals the bottle and controls water flow. Over time, it can crack, warp, or lose its seal, causing leaks or slow water release. If you own a large Petmate Pet Cafe Waterer, Aspen Pet Deluxe Waterer, or Aspen Pet Gravity Waterer (2.5–3 gallon size), you can order a direct replacement cap rather than buying a whole new waterer.

Ensures you buy the correct cap for your specific waterer model and size.

Replacement Cap (Lid) for Pet Cafe and Aspen Pet® Large Gravity Waterers - Replacement Cap (Lid) for Pet Cafe and Aspen Pet® Large Gravity Waterers: Confirm which size waterer you have prior to ordering to ensure you receive the correct replacement cap. A wrong cap won't fit or seal properly, leading to continued leaks or no water flow.
How to Replace the Gravity Waterer Cap
Replacing the cap is straightforward. The catalog does not provide full step-by-step instructions, but the general process is:
- 1. Remove the old cap: Twist off the old plunger cap from the bottle. If it's stuck, run warm water over the threads to loosen it.
- 2. Clean the bottle threads: Wipe the bottle opening to remove debris or mineral deposits that could prevent a tight seal.
- 3. Install the new cap: Screw the replacement cap onto the bottle until snug. Do not overtighten, as this can crack the plastic.
- 4. Test for leaks: Fill the bottle, attach it to the base, and check for dripping. If it leaks, tighten slightly or inspect the gasket.
