Why You Might Need PHOENIX GRAVITY Hole Blockers
If you own a gravity-fed water filtration system, you might face certain issues like unexpected leaks or inconsistent water flow. These problems often arise when your system’s filter holes are not fully utilized or capped.

Design & Build Quality
What impresses most is the quality of the plastic used. It’s thick but not brittle, offering a satisfying durability that helps you trust these plugs will last. The plugs fit snugly without requiring force, yet they are easy to remove when necessary. This balance is crucial because poorly fitting plugs can lead to leaks or damage.
One user shared, “The fit is just right—not too tight or loose. I used them with my Berkey, and they sealed the holes perfectly with no drips, which made the whole system less messy.” This customer experience highlights the product’s practical design and compatibility.
The high-quality polypropylene is also heat-resistant, which means the plugs maintain their shape and function over time, even when exposed to warm water. Impact-resistance assures you won’t have to worry if the plugs get bumped or dropped.
The fact that these hole blockers are designed to work with several popular brands like Purewell and Waterdrop adds to their versatility. They’re the type of accessory that fits seamlessly into your current filtration setup without needing adjustments or tweaks.

Real-World Performance
In everyday use, these hole blockers really shine by preventing drips and leaks from unused filter openings. I tested them with a Berkey system while running a partial filter setup to see how well they seal. The result was zero leakage, even when the water reservoir was full and under pressure.
The tight seal means less water wasted and cleaner counter surfaces without random drips. It also offers peace of mind knowing no contaminants can enter through the plugged holes. The food-grade plastic reassures you that your filtered water’s purity remains intact.
One user noted: “I was tired of the slow drip from my Waterdrop filter’s unused holes. After installing these blockers, the annoying leaks stopped completely. They’re easy to handle and give a perfect seal.”
This accessory lets you control the flow and operation of your gravity-fed filter system better. Whether you are running one or multiple filters, or you want to shut off certain outlets temporarily, these plugs make it effortless.

What Makes It Stand Out?
Compared to other hole blockers, the PHOENIX GRAVITY plugs stand out by covering a wide range of gravity-fed filter brands. Many blockers are made only for single brands or odd-shaped holes. These fit different hole sizes and systems, which makes them versatile.
In contrast, some competitors offer rubber stoppers that wear down faster or don’t create such a tight seal. PHOENIX plugs use polypropylene plastic, which is both heat- and impact-resistant. This means they last longer without needing frequent replacements.
Another plus is the easy fit that doesn’t require special tools. You can quickly plug or unplug holes without fussing with sealants or complicated installation.
In summary, these hole blockers offer a rare balance of compatibility, durability, and ease of use that helps maintain and customize your water filtration system effortlessly.
