Rōpū Rere RāHe tino kounga teitei te hanga o te manifold, he tino rongonui, he pai hoki ki ngā kiritaki o te ao katoa. Engari kei te raru tonu ētahi atu wheketere i te turuturu o te manifold ina whakamahia ana i roto i te pūnaha whakamahana papa.

1. Mena kei te turuturu te puna wai whakamahana papa, tirohia tuatahi te wāhi o te turuturu, ka tātarihia te take. Mena he turuturu kei te hononga, ka taea e koe te takai āta i te rīpene matū koiora ka huihui anō.

2. He tikanga whakamahana matatau te whakamahana papa hihi. Ko tōna kaupapa mahi he tuku i te wai wera e rere ana ki te koropiko paipa whakamahana i raro i te papa, i ngā taera papa rānei, he whakatakoto rānei i ngā taura whakamahana hei whakamahana i te papa. Ka haere te wera mā roto i tētahi wāhi nui o te whenua, ā, ka horahia te nuinga ki te wāhi i runga ake i te papa ka memeha ōrite, kia taea ai e te tinana tangata te rongo i ngā pānga wera e rua o te wera me te pāmahana o te hau.

Ko te pūnaha whakamahana papa e wehea whānuitia ana kia toru ngā wāhanga: 1> Pūnaha whakamahana (kohua nui e whakamahana ana i a ia anō mō ​​te whakamahana pokapū, ngā kohua whakairihia ki te pakitara, ngā oumu hau, me ētahi atu) 2> Pūnaha whakahaere (whakawhitinga, tātari maha-mahi, takirere aukati wai o muri, papu whakaranu, papu hurihuri me ētahi atu) 3> Pūnaha whakawhiti wera (tae atu ki te papa whakamahana, te pepa kanapa me te mata maitai pumau, me ētahi atu)

Ko te pūnaha whakamahana papa te pokapū whakahaere o te whakamahana waiariki o roto katoa. Ko tāna mahi he wehewehe i te rere me te pēhanga. Ina rere te wera ki roto i te rūma, ka uru ki te paipa matua o te pūnaha wai i muri i te haere mā te tātari maha-mahi. I tēnei taahiraa, ka tātarihia e te tātari te wera kia kore ai e uru ngā poke ki te whatunga paipa o raro whenua hei aukati i te paipa. Ka tāutahia te paipa matua ki te whakapae. Mā tēnei ara, mā te whakamahi i te kaupapa o te teitei ōrite me te pēhanga ōrite, ka tohatohahia te wera ki ngā paipa peka. Whai muri i te pūnaha whakawhiti wera, ka rere anō ngā paipa peka ki te paipa matua o te pūnaha kohikohi wai, kātahi ka rere mai i te putanga wai o muri ki te pūnaha whakamahana. Hei tāpiri, ka tāpirihia he taputapu whakaranu wai ki te whakamahana-ake, ko te tikanga i muri i te whakawhiti wera, kei te tino teitei tonu te pāmahana o te wai wera. I taua wā anō, ka taea te penapena pūngao.
