1) ʻO ka paipu PVC a me ka hoʻokomo kūpono

Nā hiʻohiʻona
ʻAʻohe mea ʻawaʻawa: ʻaʻohe mea hoʻohui metala kaumaha
Pale ʻino: kūʻē i nā mea kemika, ʻino kemika electron a i ʻole ka ʻōpala
Nā kumukūʻai hoʻokomo haʻahaʻa: ke kaumaha māmā a me ka maʻalahi o ka hoʻokomo
ʻO nā paia o loko maʻemaʻe: haʻahaʻa haʻahaʻa a ʻoi aku ka nui ma mua o nā paipu metala
Ola lōʻihi: ʻoi aku ma mua o 50 mau makahiki ma lalo o nā kūlana maʻamau
Hana hou ʻia a pili kaiapuni

Nā noi
lepo a me ka ʻōpala hoʻolele paipu i loko o ka hale
paipu wai ua i loko o ka hale
kanu ʻia nā paipu hoʻoheheʻe wai me ke kaomi ʻole i ka lepo

2) ʻO ka paipu PVC a me nā pono kūpono

1. ʻO ke kaumaha māmā: ʻo 1/6 wale nō ke kaumaha o ka lōʻihi o nā paipu hao.
2.High ikaika: hiki mai ka ikaika tensile ma luna o 45 Map.
3.Low kū'ē: he laumania ka paia o loko a pale i ka scum buildup.ʻO ke kaomi wai a me ka hoʻokuʻu ʻana o ka paipu PVC-U he 30% haʻahaʻa ma mua o nā paipu hao me ke anawaena like a hiki ke mālama i ke kumukūʻai o ka mana hoʻokuʻu.
4.Corrosion kū'ē: kū'ē maikaʻi loa i ka corrosion i hanaʻia e nāʻakika, alkaline, kemika a me ka uila, no lailaʻaʻole e hana i nā stains.
5.Easy hoʻokomo: hoʻopili maʻalahi me nā apo lāʻau.He maʻalahi ke hoʻouka a hoʻopaʻa maikaʻi.
6.Long lifespan: ma lalo o nā kūlana maʻamau hiki ke ola i ka 50 makahiki.
7.Low kumu kūʻai: me ke kumu kūʻai haʻahaʻa o ka hoʻokomo.ʻO ka halihali a me nā mea waiwai, ʻo ka nui o ke kumukūʻai o ka ʻenekinia e hana ʻo PVC-U 30% haʻahaʻa ma mua o nā paipu hao.
