Ngā papuhe taputapu miihini e whakamahia ana mō te kawe wai, mō te whakanui rānei i te pēhanga wai, ā, e whakamahia whānuitia ana i roto i ngā ahumahi pēnei i te hanga, te hanga, te ahuwhenua, te tuku wai, me te whakamahana, te hauhautanga me te hauhautanga (HVAC). E ai ki ō rātou whakamahinga me ngā mātāpono mahi, ka whakarōpūtia ngā papu wai ki ngā kāwai e whai ake nei:

Papu pūwero: Ko te momo papu wai tino noa, ka kawe i ngā wai mā te whakaputa i te kaha pūwero mā te hurihanga tere o te impeller. He pai mō te kawe wai ma, ngā pūnaha tuku wai, te tohanga hauhautanga, ngā pūnaha tiaki ahi, me ētahi atu. Ko ōna āhuatanga ko te tere rere nui, te hanganga māmā me te tiaki watea.
Ngā papu ruku: Kua honoa te motuka me te tinana papu, ā, ka taea te whakanoho tika ki roto i te wai hei whakahaere. He mea whakamahi noa ēnei mō te tango wai i roto i te puna hohonu, te tukunga paru, te tango wai i raro i te whenua me te maimoatanga paru. He ngāwari te tāutanga me te tino whai hua.
Papu whakanui: E whakamahia ana hei whakanui i te pēhanga wai, e kitea whānuitia ana i roto i ngā whare teitei, i ngā pūnaha pēhanga whakamahana wai whare me ngā pūnaha pēhanga paipa ahumahi.
Papu whakapūmau-ake: Ka taea te utu wai aunoa, ā, kāore e hiahiatia he whakakī wai auau hei tīmata. He pai mō te whakamakuku ahuwhenua, te whakaheke wai kaipuke me te kawe wai matū.
Ngā papu taputapu me ngā papu pūwero: Ko te nuinga o te wā ka whakamahia mō te kawe i ngā wai pēhanga teitei, wai motuhake rānei, pērā i ngā hinu me ngā matū.

Ko te mahi matua o te papu wai ko te kawe wai, te tohanga, te pēhanga, te rerenga wai me te whakamakuku, kia mau ai te mahi a ngā pūnaha wai i roto i te hanga ahumahi me te oranga o ia rā. He taputapu matua tēnei i roto i ngā pūnaha kawe wai.
