ʻO ka pahu pahu pahu pahu pahu pahu he ʻano maʻamau o ka pahu i loaʻa i kahi mea keleawe a me kahi pahu plastik. Hoʻohana nui ʻia ia e kāohi i ke kahe o ka wai a i ʻole ke kinoea i loko o ka pipeline a pale i ka hoʻihoʻi ʻana a i ʻole ke kahe ʻana.
ʻO Brass kahi mea kiʻekiʻe me ke kūpaʻa corrosion maikaʻi a me ka ikaika, hiki ke mālama i ka hana paʻa ma lalo o nā kūlana hana like ʻole. Hana ʻia ka pahu pahu palaki i nā plastic engineering kiʻekiʻe, nona ka hoʻopaʻa maikaʻi a me ke kūpaʻa corrosion, a hiki ke hōʻoia i ka hoʻopaʻa ʻana a me ka paʻa o ka valve.
He maʻalahi ka hoʻonohonoho ʻana o ka valve check, hoʻonohonoho maʻalahi a mālama, mālama i ka manawa a me nā koina hana.
Hoʻohana nui ʻia nā pahu pahu pahu keleawe keleawe i ka ʻoihana, ke kūkulu ʻana, ka lako wai kīwila a me nā ʻōnaehana wai, a me nā mea ʻē aʻe, a hiki ke hoʻohana ʻia e pale i ka hoʻihoʻi ʻana o ka wai, backflow o ke kinoea, a me nā mea ʻē aʻe, a e hōʻoia i ka hana maʻamau o ka ʻōnaehana pipeline.
