Prime Compatible Gravity Filter Elements with Faucet Pressure
This reusable silicone priming tool helps prepare new gravity filter elements and re-prime compatible filters when trapped air affects water flow. Instead of repeatedly squeezing a manual pump, the tool uses controlled household faucet pressure to move water through the filter media.
Core Product Benefits
Designed to simplify filter preparation and support consistent flowUses controlled faucet pressure to move water through the filter media without repeated hand squeezing.
Helps displace air pockets inside dry filter media so water can pass through the element more evenly.
Priming may help improve the flow of compatible new or previously used filters affected by trapped air or loose debris.
No batteries, electrical connection or complicated equipment is required for normal priming.
How the Priming Process Works
Connect the filter, create a faucet seal and begin with low water flowRemove the wing nut and two filter washers from the threaded stem of the compatible gravity filter element.
Fit the narrow connection of the silicone tool securely over the exposed threaded filter stem.
Press the wide silicone end inward to form a concave shape and hold it firmly against the faucet outlet.
Open the faucet slowly and rinse at a low flow for approximately 60 seconds, or until the water leaving the filter runs clear.
Compatibility Information
Confirm both faucet dimensions and filter connection before useCompatible Gravity Filter Elements
Designed for Purewell gravity filter elements and many compatible threaded filters with a similar priming connection. It may also work with selected Black Berkey, ProOne and BB9-2-style replacement filter elements.
Recommended Faucet Diameter
12–25 mmThe stretch-fit silicone opening is suitable for many common round or similarly shaped faucet outlets within this diameter range.
Care & Use Information
Clean and inspect the reusable silicone tool after each useRinse the priming tool with clean water before connecting it to the faucet and filter element.
Rinse away loose filter particles and residual water after the priming process is complete.
Allow the silicone tool to dry in a clean, ventilated area before placing it with the filter accessories.
Replace the tool if the silicone becomes torn, cracked, permanently stretched or unable to maintain a secure seal.
