The filter remains inside the upper tank. Its rod passes through the bottom of this tank and receives the nut from below. The seal remains on the filter side, inside the tank.
Hold the filter while screwing in, then tighten the nut by hand. If the threads catch, unscrew and realign the part. Tightening too hard can damage the thread and cause a leak.
The reference XW-NUT designates the Black Berkey® filter nut. Compare it to the part to be replaced to avoid ordering a nut intended for the faucet or another accessory. For two filters to be equipped, provide two nuts.
Coming from a pharmaceutical background, I select each system with a requirement for reliability and transparency — for pure water, without complex installation, which preserves essential mineral salts.
