The air in the cartridge is displaced by the waler and purged from beneath the (ilter hood through the one-way check vaive located in the cap. Once the center tube is � filled with water (approximately 18 inches deep), there is enough buoyant force on the iloat to open the float valve and allow the lrealed water in !�ie center tube to (low into the under-drain manifold.
