Whakaahuatanga
Ko te poaka whiwhi me te whakarewatanga retireti, e kiia ana ko te poaka tuku me te kaiwhiwhi, e kiia ana ko te whiwhi me te whakarewatanga rango, no roto i ngā taputapu paipa, e whakamahia whānuitia ana i roto i ngā paipa kawe reo.
Ko te tikanga, ka tāutahia ki ngā pito e rua o te paipa matua hei tuku me te whiwhi i te poaka, ā, ka taea te whakamahi hei horoi i te ware pi, hei muru hinu me te tango i te unahi i mua me muri i te whakaurunga o te paipa ki te hanga. E ai ki ngā hiahia o ngā kaiwhakamahi, ka taea te hoahoa i te reti mō te whakamahinga e rua ngā taha.
He taputapu tukatuka nui te kaiwhiwhi me te kaiwhakarewa mō te whiwhi me te tuku taputapu poaka i te wā e horoi ana i ngā paipa.
Ko te kaiwhiwhi me te whakarewa he mea tito mai i te pereti matapo whakatuwhera tere, te tinana oko, te hononga diameter-rerekē, te wāhanga paipa tika, te paipa tukatuka, te tautoko momo nohoanga me ētahi atu. Kei roto i te pereti matapo whakatuwhera tere te taupoki matapo, te flange oko, te taputapu raka haumaru, te tikanga whakatuwhera me te kati me te anga tautoko.
Ko te mahi raka haumaru o te pereti matapo he mea tito mai i te pereti raka haumaru me te taputapu whakamāmā pēhanga (he raka-ā-unoa te pereti matapo, he ātete ru, he ātete wetekina, ā, ka taea te whakatuwhera mō te whakamāmā pēhanga tuarua).
I mua i te whakamahinga o te paipa tuku hau, ka taea e te reti te tango i te paru, ngā taputapu i mahue me ētahi atu para i roto i te paipa;
I muri i te whakamahinga o te paipa tuku hau, ka puta mai te wai whakapūhau i te hekenga o te pāmahana o te hau māori me te wai kua mākū. I taua wā anō, ka waikura te paipa e te hau māori kei roto he whanariki, ka piki ake te taratara o te pakitara o roto o te paipa, ka pā ki te pai o te tuku hau. Ka taea e te taputapu tuku me te taputapu kaiwhiwhi te tango i te wai me ngā poke i roto i te paipa, me te whakapai ake i te pai o te tuku hau.
