BWT Bestflush バルブ - 新しいカートリッジの洗浄用

Installed it on our under-sink filter and the flush process was finally straightforward—the twist-to-open design let me easily clear out all the carbon dust before regular use.

It took me maybe two minutes to screw this on and run water through the new cartridge. The flow was steady and I could see the air bubbles clear out fast, so no messy priming hassle afterward.

Installing the filter was a breeze once I used this flush valve to prime it—took less than a minute to purge the air. The valve itself feels solid and works exactly as intended.
