Quick answer
To replace a gravity waterer cap, first confirm the size of your waterer, then remove the old cap, clean the threads, and screw on the new cap until snug. Avoid overtightening to prevent cracks.
Why cap size matters
Gravity waterer caps are not one-size-fits-all. The Lebistro cap for the Extra Small (1/2 gallon) waterer has a different thread and diameter than the Replendish cap for medium and large systems. Using the wrong cap can cause leaks or poor sealing, which may lead to water waste or contamination.
Check the model number or capacity printed on your waterer before ordering. If you have a Lebistro, look for the 1/2 gallon mark. For Replendish, the medium holds 2.5 gallons and the large holds 4 gallons. Matching the cap to the correct size ensures a tight fit.
When to replace the cap
Replace the cap if you notice cracks, warping, or if the waterer no longer seals properly. Over time, plastic can become brittle from sun exposure or frequent cleaning. A worn cap can let in debris or cause the waterer to drip.
Regularly inspect the cap during cleaning. If the threads look stripped or the cap feels loose, it's time for a replacement. Petmate recommends checking watering system parts periodically to maintain your pet's health.
How to replace the cap in 4 steps
- 1. Confirm your waterer size: Look for the capacity marking on the base or bottle of your gravity waterer. For Lebistro, check if it's 1/2 gallon. For Replendish, note whether it's medium (2.5 gals.) or large (4 gals.). Order the cap that matches your exact model. Mixing sizes is the most common cause of leaks.
- 2. Remove the old cap: Twist the old cap counterclockwise until it comes off. If it's stuck, run warm water over the cap to expand the plastic slightly. Do not use tools that could crack the cap. Inspect the old cap for cracks or worn threads. If damaged, discard it.
- 3. Clean the threads: Wipe the threads on the waterer bottle with a damp cloth to remove debris or mineral deposits. Let them dry completely before installing the new cap. Dirty threads can prevent a proper seal, leading to slow leaks.
- 4. Install the new cap: Place the new cap on the bottle and turn it clockwise until it is snug. Do not overtighten—hand-tight is sufficient. Fill the waterer and check for drips before placing it back in the stand. If the cap leaks, remove it, check the threads for damage, and try again. A persistent leak may mean the cap is the wrong size.
