Hoʻokumu ʻia ka pahu wafer check valve me ka valve kino, valve disc, valve stem, spring a me nā ʻāpana ʻē aʻe. Hoʻohana ia i ka pilina wafer. Ma muli o ka pōkole pani pani o ka valve disc a me ka hoʻouka ʻana i ka puna, hiki ke hoʻemi nui ʻia ke ʻano hammer wai. He kūpono kēia valve no ke kūlanakauhale, ka ʻoihana a me ka hale kiʻekiʻe o ka hale kiʻekiʻe a me nā ʻoihana paipu wai. No ka mea, ʻoi aku ka pōkole o kona lōʻihi ma mua o nā valve check maʻamau, ʻoi aku ka maikaʻi no nā wahi me nā kau palena.
