Neke atu i te 50 tau te roa mai i te whakaurunga mai o te takirere pūrerehua takitoru, ā, kua whanake tonu i roto i ngā tau 50 kua hipa. Kua horapa te whakamahinga o ngā takirere pūrerehua ki ngā ahumahi maha. Ko te takirere pūrerehua taketake ka whakamahia anake mō te hopu me te hono i ngā rauemi wai. Ka whakarei ake te hoahoa takirere takitoru i te mahi a te takirere pūrerehua. Kua noho ko tētahi o ngā takirere he tino pai te mahi i raro i ngā āhuatanga tino uaua i roto i te taiao tukanga nui i roto i ngā taputapu paipa ahumahi.

E ai ki te ingoa, e toru ngā āputa motuhake kua hangaia hei takirere. Ko te tikanga o te āputa toru:

• Wāhi Whakakore 1

Ka whakatakotoria te kakau ki muri i te mata o te mata hiri hei whakarato i te ara nohoanga tonu.

• Wāhanga 2

Ka whakatakotoria te rakau ki tetahi taha o te pokapū o te paipa/valve hei whakakore i te waku i waenga i te hiri me te nohoanga.

• Wāhanga 3

He anga whakarara ngā rārangi pokapū o te nohoanga me te hiri ki te rārangi pokapū o te paipa/takirere. Mā tēnei rerekētanga tuatoru ka kore rawa e mirimiri. Mā tēnei koki kōne, me ngā rerekētanga rakau rerekē e rua, ka taea e te kōpae te hiri ki te nohoanga me te kore e waku.

Mā tēnei hoahoa nohoanga ka taea te hiri ōrite, ā, ka taea te kati pūmau i te hoahoa nohoanga whakarewa. He iti ake te utu o tēnei hoahoa, he iti ake te taipana (he māmā ake te aunoa), i ngā takirere nohoanga whakarewa momo kē atu.

Ko ngā taupatupatu takitoru e whakamahia whānuitia ana i roto i ngā mahi pēnei i te mamaoa pēhanga teitei (neke atu i te 150 PSI), te mamaoa wera rawa, ngā hau me ngā hinu pāmahana teitei, he pai ngā mahi pāmahana teitei mō tēnei momo takirere nā te mea me whai nohoanga whakarewa ki runga i te nohoanga ngohengohe.
