Ko te mea pono, ehara ngā paipa ahumahi i te porowhita tino, ā, he mea noa tēnei āhuatanga. Ko ngā take matua koia ēnei: Ka hangaia ngā paipa maitai kore hononga ahumahi mā te hurihuri matao, mā te totoro wera rānei. Ko te whānui o te paipa ka tae ki te ≤DN2000, ā, ka whakaaetia he hapa porowhita. Heoi anō, ko te porowhita o ngā paipa maitai e pā tata ana ki te mea i hangaia e ngā umanga maitai nui, ā-ture rānei, he rerekē ngā kounga. He iti rawa te porowhita o ngā paipa maitai waitohu, engari he iti noa iho te porowhita o ngā paipa maitai kāore i waitohutia. Mō ētahi paipa maitai DN300, ka taea e te hapa whānui mōrahi te eke ki te 5mm. Haunga ngā paipa maitai kore hononga, he maha ngā paipa e whakamahia ana mō te kawe wai iti-pēhanga he paipa whakapiripiri porowhita. He kino rawa atu tō rātou taupū porowhita i ērā o ngā paipa maitai kore hononga i hangaia ā-mīhini. Me mōhio tātou ki ēnei āhuatanga ina whakamahia ēnei paipa mō ngā kaupapa ine. Kāore he pānga o te porowhita o ngā paipa maitai ki te kawe wai i roto i te tukanga whakaputa ahumahi. Heoi, ina tae mai ki ngā tono ine rere, pērā i te whakapūmau o waho me te whakaurunga o ngā mita rere ultrasonic, me ētahi atu taputapu rere momo whakaurunga rānei, ki te nui te rerekētanga o te porowhita, ka pāngia ia. I te wā e tāuta ana ki te papaanga, me aro ki te whiriwhiri i tētahi wāhanga o te paipa he pai ake ngā āhuatanga.
