He maha ngā momo rawhi ngongo i roto i tō tātou ao. Ā, kotahi te momo rawhi paipa — te rawhi whakairi, e whakamahia nuitia ana i roto i te hanga. Kātahi ka mōhio koe ki te mahi a tēnei rawhi?

He maha ngā wā ka tika kia haere ngā paipa me ngā pūnaha wai e pā ana mā roto i ngā kōhao, i ngā tuanui, i ngā ara hikoi i raro i te whenua, me ērā atu mea. Hei ārai i ngā ara e nekehia ai te tangata, te taonga rānei, engari kia mau tonu ai te rere o te wai mā roto i te rohe, me āwhina kia piki ki runga i ngā pakitara, me whakairi rānei i te tuanui.

Ka mahia tēnei mā te whakakotahi i ngā tokotoko e piri ana ki te tuanui i tētahi pito, me ngā rawhi i tētahi pito. Ki te kore, ka herea ngā paipa ki ngā pakitara mā te rawhi ki te pupuri i a rātou kia teitei. Heoi, kāore e mahi tetahi rawhi ngāwari. Me āhei ētahi ki te whakahaere i te pāmahana. Me mau tonu ia rawhi kia kore ai e nekeneke i roto i te paipa. Ā, me āhei hoki ki te aro atu ki ngā huringa whānui o te whakarewa paipa ka nui ake, ka iti ake rānei te diameter i te makariri, i te wera rānei.
Ko te māmā o te rawhi paipa e huna ana i te hiranga o tana mahi. Mā te pupuri i te paipa kia mau tonu, ka āwhina te taputapu kia mau tonu ngā wai, ngā hau rānei e neke ana i roto i te wāhi e tika ana, kia tae atu hoki ki ō rātou ūnga. Mēnā ka wetekina te paipa, ka maringi tonu ngā wai i roto ki te wāhi tata, ka poke rānei te hau i te āhua ōrite. Mō ngā hau pūngāwerewere, ka taea e ia te arahi ki ngā ahi, ki ngā pahūtanga rānei. Nō reira, he mahi nui ngā rawhi, kāore he tautohe.
Ko te hoahoa taketake rawa atu o ngā rawhi paipa ko te putanga paerewa e rua ngā wāhanga e puritia ana e ngā tīwiri. Ka wehea te rawhi kia rua ngā wāhanga ōrite e karapoti ana i te haurua o te paipa. Ka honoa ngā wāhanga mā te whakapiri i te paipa ki waenganui, ā, ka mau mā ngā tīwiri e pupuri pūmau ana i ngā rawhi.
Ko ngā mea tino taketake o ngā rawhi paerewa he mea hanga ki te konganuku tahanga; ko te mata o roto e tū tika ana ki te kiri paipa. He momo whakamātao anō hoki. He rapa, he rauemi rānei kei roto o ēnei momo rawhi, e whakarato ana i tētahi momo urunga i waenganui i te rawhi me te kiri paipa. Ka taea hoki e te whakamātao te whakarerekē i ngā huringa whānui nui ina he take nui te pāmahana.
