Paipa tapawhā piauauHe mea hiko te whakapūmau, he iti noa te nui o te whakapūmau, 10-50g/m2 anake, he rerekē rawa tōna ātete ki te waikura i ngā paipa whakapūmau wera. Hei whakarite i te kounga, ko te nuinga o ngā kaihanga paipa whakapūmau noa kāore e whakamahi i te whakapūmau hiko (whakakikorua makariri). Ko ngā umanga iti anake me ngā taputapu tawhito e whakamahi ana i te whakapūmau hiko, he iti noa iho ā rātou utu. Kua panuitia mana e te Manatū Hanga te whakakorenga o ngā paipa whakapūmau makariri me ngā hangarau tawhito, ā, kāore e whakaaetia kia whakamahia ngā paipa whakapūmau makariri hei paipa wai me te hau. Ko te paparanga whakapūmau o te paipa maitai whakapūmau makariri he paninga hiko, ā, he paparanga motuhake te paparanga konutea me te hanganga paipa maitai. He angiangi te paparanga konutea, ā, he piri noa te paparanga konutea ki te hanganga ngongo maitai, ā, he ngāwari ki te taka. Nō reira, he ngoikore tōna ātete ki te waikura. I roto i ngā whare noho hou, kāore e whakaaetia kia whakamahia ngā paipa maitai whakapūmau makariri hei paipa tuku wai.
