Hummingbird feeders leaking can be a common issue that frustrated hummingbird enthusiasts face. There are a few key reasons why Perky Pet hummingbird feeders may start to leak over time.
Cracks in the Plastic
One of the most common reasons Perky Pet feeders can start to leak is due to cracks forming in the plastic over time. This can happen for a few reasons:
Exposure to Sunlight
Excessive exposure to UV sunlight can slowly cause the plastic material to become more brittle and eventually crack. Leaving the feeder in direct sunlight day after day can accelerate this process. Cracks then form causing leaks.
Freezing Temperatures
If there is leftover nectar in the feeder during freezing winter temperatures, this can expand and put pressure on the plastic, eventually causing cracks or splits. Even slight cracks from this pressure can then result in leaks.
Wear and Tear
General wear and tear over months/years of use can also start to degrade the plastic. Even small surface cracks that form on the outside of the reservoir or seams can allow nectar to slowly seep out.
Improper Sealing
Issues with the feeder sealing properly can also lead to unwanted nectar leaks. There are a couple reasons this can happen:
Feeder Base Not Fully Secured
If the threads connecting the base to the reservoir are not fully tightened or have worn down, gaps can form where nectar can leak out. This can happen if the base is not regularly checked for a snug fit.
Broken Seal
The rubber O-ring seal that helps prevent leaks also degrades over time. When this seal dries out and cracks, it can no longer properly contain the nectar in the reservoir. Checking this seal annually helps avoid leaks.
Blocked Feeding Ports
When the feeding ports become partially blocked, pressure can start to build up. This increased pressure pushes nectar through any small gaps or cracks in the plastic, causing leaks or drips.
Built-Up Mineral Deposits
Mineral deposits from tap water or cleaned with soap can gradually build up on the feeding ports. This needs to be cleaned regularly to avoid blockages.
Mold Growth
If nectar is left for too long, mold growth can start clogging the ports. Any drips can then leak through cracks rather than the ports.
Solutions for Preventing Leaks
Luckily there are some steps you can take to help prevent and fix any leaking issues:
- Inspect for cracks – Carefully examine the reservoir for any small cracks or splits. Look along seams and the base connection.
- Check the seal – Examine the rubber O-ring seal for cracks or drying out. Replace if needed.
- Clean ports – Use a small brush and vinegar to remove any mineral buildup or mold clogs.
- Tighten base – Ensure the threaded base connection is fully tightened and secured.
- Move location – Avoid leaving the feeder in direct sunlight. Move to a shaded area.
- Take down in winter – Clean and take down the feeder during freezing temps to avoid ice damage.
- Replace if needed – Heavily worn/damaged feeders may need full replacement.
Typical Leaking Problems
Here are some of the most common leaking issues and their likely causes:
| Leaking Issue | Likely Cause |
|---|---|
| Slow drips from the base | Base not fully tightened, worn base threads |
| Nectar pooling under feeder | Crack in reservoir, dried out seal |
| Leaks from flower feeding ports | Blocked ports from mineral deposits or mold |
| Dripping through ventilation holes | Build up of internal pressure from clogged ports |
Materials That Prevent Leaks
Perky Pet makes feeders from various plastic materials. Some hold up better than others:
Glass
Glass reservoirs are essentially impervious to cracking from weather or UV light. They do not degrade like plastics. However, they are heavier and can shatter if dropped.
Tritan Plastic
Tritan plastic is a type of polycarbonate that maintains its strength and flexibility even after prolonged UV exposure. Much less susceptible to sunlight cracking.
ABS Plastic
ABS is also resistant to weathering but not quite as flexible as Tritan blends. Still performs better than cheaper plastics.
Acrylic Plastic
Acrylic is lighter but tends to become more brittle over time. Has a higher chance of developing stress cracks from freezing or UV light.
Ideal Nectar Fill Level to Prevent Leaks
Filling the nectar reservoir to the proper level can help reduce leaks. Recommended fill levels:
- For 8-12 oz capacity reservoirs – fill to approximately 10 oz level
- For larger 16-20 oz capacity – fill to around 14 oz level
- Avoid completely filling to brim, leave 1-2 inches of space
- Refill when nectar drops to half full
Overfilling increases pressure on seals and plastic walls. It also raises the chance of nectar forcing itself through small cracks. Leaving some empty space allows for nectar expansion on hot days.
Nectar Volume Leak Prevention Recommendations
| Reservoir Size | Ideal Fill Amount |
|---|---|
| 8 ounce | 6 – 7 ounces |
| 12 ounce | 8 – 10 ounces |
| 16 ounce | 10 – 12 ounces |
| 20 ounce | 12 – 14 ounces |
Keeping the Reservoir Clean
Regular cleaning and maintenance can also help avoid leaks. Follow these best practices:
Cleaning Solution
Use a solution of 1 part white vinegar mixed with 4 parts water. Vinegar helps dissolve mineral deposits and kill mold.
Weekly Port Cleaning
Use a small brush dipped in the vinegar solution to scrub the feeding ports weekly. This will prevent clog buildup.
Monthly Deep Cleaning
Take apart the reservoir monthly and soak all pieces in the vinegar solution, scrubbing thoroughly to remove grime buildup. Rinse well before reassembling.
Pre-Season Inspection
Check for cracks and replace seals before hanging up the feeder each season. This helps it start out clean and leak free.
Conclusion
Perky Pet hummingbird feeders are generally well made but plastic parts and seals can degrade over time leading to leaks. With some basic maintenance like cleaning the ports, inspecting for cracks, replacing seals, and taking down during freezing weather, these reliable feeders can give you many seasons of enjoyment watching hummingbirds without the mess of dripping nectar.
