1. Mō te whakapaipai whare, he pai ake te whakatakoto i te paipa wai ki runga, kaua ki raro ki te whenua, nā te mea kua tāutahia te paipa wai ki runga i te whenua, ā, me pikau e ia te pēhanga o ngā taera me ngā tāngata i runga, ā, he tūponotanga kei takahia te paipa wai. Hei tāpiri, ko te painga o te hikoi i te tuanui he watea mō te tiaki. Arā, he tino nui te utu, ā, kāore te nuinga o te tangata e whakamahi ana;

2. Ko te hohonutanga o te paipa wai kua haehaea, ko te paparanga pungarehu i muri i te tanumanga o te paipa wai matao me neke atu i te 1 cm, ā, ko te paparanga pungarehu i muri i te tanumanga o te paipa wai wera me neke atu i te 1.5 cm;

3. Te Whakapūtanga Parahi Me whai ngā paipa wai wera me te wai matao i te kaupapa o te wai wera i te taha maui, me te wai matao i te taha matau;

4. Ko ngā paipa rewa wera PPR e whakamahia whānuitia ana mō ngā paipa tuku wai. Ko te painga he pai te hiri me te tere o te hanganga, engari me whakamahara ki ngā kaimahi kia kaua e tere rawa. Mēnā ka whakamahia he kaha hē, ka āraia pea te paipa, ā, ka whakaitihia pea te rere o te wai. Mēnā he horoi wharepaku. Mēnā ka pā tēnei ki te paipa wai takirere, e kore te moenga e horoia kia ma;

5. I muri i te whakatakotoranga o ngā paipa wai, ā, i mua i te hiritanga o ngā awaawa, me whakamau ki ngā rawhi paipa. Kaua e neke atu i te 60 henimita te tawhiti i waenga i ngā rawhi paipa wai matao, ā, kaua e neke atu i te 25 henimita te tawhiti i waenga i ngā rawhi paipa wai wera;

6. 'Ko te tawhiti i waenganui i ngā rawhi paipa whakapae, ko te tawhiti i waenganui i ngā rawhi paipa wai matao kaua e neke atu i te 60 cm, ā, ko te tawhiti i waenganui i ngā rawhi paipa wai wera kaua e neke atu i te 25 cm;

7.Me rite te teitei o ngā pane o ngā paipa wai wera me te wai matao kua tāutahia. Mā tēnei anake ka taea te tāuta i ngā pana wai wera me te wai matao a muri ake nei kia ataahua ai.
