Ngā Painga

• Hanganga Māmā: Ko te nuinga o te wā he wāhanga miihini pēnei i ngā impeller, ngā taputapu, me ngā mata waea, kāore he wāhanga hiko uaua, nō reira he tino māmā tōna hanganga.
• Utu iti: Nā te ngāwari o te hanganga me te tukanga hanga, he iti ngā utu rauemi mata me ngā utu whakaputa. He utu tika, ā, he pai mō te whakatairanga me te tono nui.
• Kāore he Pūnaha Hiko e Hiahiatia: Ka whakawhirinaki ki te kaha o te rere o te wai hei akiaki i te hurihanga o te impeller mō te ine, me te kore e hiahiatia he pūnaha hiko o waho. Mā tēnei ka karohia te āhuatanga e kore ai e rahua te ine nā te motuhanga o te hiko.
• Te Pūmautanga Teitei: Kāore e pāngia ngāwari e ngā take o waho pēnei i te pokanoa hikohiko. Ka taea te mahi noa i roto i ngā taiao uaua pēnei i te pāmahana teitei, te pāmahana iti, me te haumākū, ā, ka mahi pūmau mō te wā roa.
• Ngāwari te Tāutanga me te Tiaki: He tino māmā te tikanga tāutanga; ko te tikanga, me tāuta noa ki runga i te paipa kia rite ki te ahunga me te tūranga kua tohua. He iti hoki te utu tiaki—ko te tikanga, ko te horoi me te whakatikatika noa iho e hiahiatia ana, me te kore e hiahiatia he tohunga ngaio ki te mahi i ngā mahi uaua.

Ngā ngoikoretanga

• Te Ine Tika Iti: Ko te tika o te ine o ngā mita wai miihini ka pāngia nuitia e ngā āhuatanga pēnei i te tere rere o te wai, te kounga o te wai, me te tikanga tāutanga o ngā paipa. Mēnā he iti te rere o te wai, ka puta pea he ine hē; mēnā he nui te rere o te wai, ka puta pea he hapa ine nā te pakaru o ngā wāhanga miihini, nā te pikinga rānei o te ātete.
• Kāore he Aroturukitanga Wā-tūturu, he Tuku Raraunga Mamao rānei: Ka taea anake te tiki raraunga whakapaunga wai mā te pānui ā-ringa i ngā uara kei runga i te mata. Kāore e taea te whakatutuki i te aroturukitanga wā-tūturu, te tuku raraunga mamao rānei, me te pānui mita ā-ringa i te papaanga, he mea koretake tēnei, ā, ka piki ake ngā utu mahi me ngā uauatanga whakahaere.
• Ngā Whakaritenga Teitei mō te Kounga o te Wai: Ka taea e ngā poke, ngā paru, te waikura, me ētahi atu matū i roto i te wai te aukati i te impeller me ngā taputapu, ka pā ki te mahi noa o te mita wai, ka pakaru rānei. Nō reira, me tāuta he tātari ki mua i te mita wai, ka piki ake hoki ētahi utu me te mahi tiaki.
• Rahi Nui: Ki te whakaritea ki ngā mita wai atamai, he nui ake te rahi o ngā mita wai ā-ringa, ā, he nui ake te wāhi e nohoia ana e rātou, e kore pea e taea te whakamahi i ētahi wāhi tāutanga he iti noa te wāhi.
• Kore e taea te Whakatutuki i te Whakahaere Maamaa: Kāore he mahi atamai, ā, kāore e taea te tautoko i ngā tikanga whakahaere atamai pēnei i ngā tatauranga raraunga aunoa, ngā whakaoho whakamahinga wai rerekē, me te whakahaere takirere mamao.
