    1. Ko tētahi o ngā painga matua o te paipa tuitui porowhita ko tōna kaha tino pai. Mā te tukanga whakarewa porowhita ka taea te whakarewa tonu, ā, ka whakarei ake i te hanganga o te paipa. Nā tēnei ka pai mō te kawe i ngā wai me ngā hau i raro i te pēhanga teitei.

    2. He whai hua te tukanga hanga, e āhei ai te hanga paipa roa ake me te kore e hiahiatia he hononga, ā, he ngoikore pea ēnei.

    3. Tētahi atu painga nui opaipa tuitui porowhitako tōna maha o ngā whakamahinga. Ka taea te whakaputa i ēnei i roto i ngā momo diameter me ngā matotoru o te pakitara mō ngā momo tono mai i te kawe hinu me te hau ki ngā pūnaha wai.

    4. Ko ngā kamupene e hanga ana i ēnei paipa e whakatairanga ana i te pai o te kaihoko, ā, e whakarato ana i ngā ratonga whānui i mua i te hoko, i te wā hoko, me muri i te hoko. Mā tēnei whakapau kaha ka whiwhi ngā kaihoko i ngā hua e hāngai ana ki ō rātou hiahia, e whakarei ake ana i te wheako whānui.

    Ngā ngoikoretanga o te hua

    1. Ka uaua ake te tukanga whakarewa porowhita i ngā tikanga whakarewa tuku iho, ā, ka nui ake pea ngā utu whakaputa.

    2. Ahakoa he kaha ngā paipa tuitui porowhita, kāore pea i te tino ātete ki ētahi momo waikura pērā i ētahi atu rauemi paipa, ā, me pania, me rongoatia rānei.

Ehara i te mea he kaha teitei te paipa hua engari he tino pakari hoki, he mea tino pai mō ngā momo mahi, tae atu ki te kawe hinu me te hau, te tuku wai me te tautoko hanganga.

    Q2: He aha i whiriwhiri ai i te paipa tuitui porowhita kounga teitei?

    Ko te painga matua o ngā paipa tuitui porowhita kounga teitei ko tōna hanganga pakari. Mā te tukanga whakarewa porowhita ka taea te whakarewa tonu, ka whakarei ake i te pakari me te ātete ki te pēhanga o te paipa. Hei tāpiri, ka taea te hanga i ēnei paipa i roto i ngā rahi me ngā matotoru rerekē hei whakatutuki i ngā hiahia motuhake o ngā kaupapa rerekē.

    Q3: He aha ngā mea me rapu e au i roto i tētahi kaiwhakarato?

    I te wā e whiriwhiri ana i tētahi kaiwhakarato ngongo tuitui porowhita, he mea nui kia whiriwhiria he kamupene e whakaū ana i te pai o te kiritaki ki te tuatahi. Rapua he kaiwhakarato e tuku ana i ngā ratonga whānui i mua i te hoko, hoko, me muri i te hoko.
