Tapu 1

Me whakahaere ngā whakamātautau pēhanga wai i roto i ngā āhuatanga makariri i te wā hanga o te hotoke.
Ngā hua: I tio te paipa, ā, i pakaru hoki nā te tio tere o te paipa i te whakamātautau wai ātete.
Ngā Inenga: Whakamātauria te pēhanga wai i mua i te whakamahinga mō te hotoke, ā, whakawetohia te wai i muri i te whakamātautau, inā koa te wai i roto i tetakirere, me horoi, ki te kore ka waikura, ka pakaru rānei, he kino rawa atu. I te wā e whakahaerehia ana te whakamātautau waipēhi i te takurua, me pupuri e te kaupapa te pāmahana o roto kia pai, ā, me pupuhi te wai i muri i te whakamātautau pēhanga.

Tapu 2

Me horoi te pūnaha paipa, engari ehara tēnei i te mea nui nā te mea kāore te rere me te tere e tutuki i ngā paerewa. Ahakoa te horoi ka whakakapia ki te tuku wai hei whakamātautau kaha waipēhi. Ngā Huanga: Nā te mea kāore te kounga o te wai e tutuki i ngā paerewa whakahaere o te pūnaha paipa, ka whakaitihia te rahi o ngā wāhanga paipa, ka āraia rānei. Whakamahia te nui o te wai ka taea te rere mā roto i te pūnaha, kia 3 m/s rānei te iti rawa o te rere wai hei horoi. Kia whakaarohia ai te putanga tuku wai, me ōrite te tae me te māramatanga o te wai ki te wai e tomo mai ana.

Tapu 3

Ki te kore e whakahaerehia he whakamātautau wai kua kati, ka hunaia ngā paipa paru, te wai ua, me te wai whakapūpū. Ngā Huanga: Tērā pea ka puta he turuturu wai, ka ngaro hoki ngā kaiwhakamahi. Ngā Mahi: Me tirotirohia, me whakaaetia hoki te whakamātautau wai kua kati kia rite tonu ki ngā aratohu. He mea nui kia whakapūmautia kei te ātete ngā mea katoa kei raro i te whenua, kei roto i te tuanui, kei waenganui i ngā paipa, me ētahi atu whakaurunga huna—tae atu ki ērā e kawe ana i te wai whakapūpū, te wai ua, me te wai whakapūpū.

Tapu 4

Ko te uara pēhanga me ngā rerekētanga o te taumata wai anake ka kitea i te wā o te whakamātautau kaha waipēhi me te whakamātautau piri o te pūnaha paipa; kāore e ranea te tirotiro turuturu. Ko te turuturu e puta ana i muri i te whakamahinga o te pūnaha paipa ka whakararu i te whakamahinga noa. Ngā Whakamahinga: Ina whakamatautauria te pūnaha paipa i runga anō i ngā whakaritenga hoahoa me ngā aratohu hanga, he mea tino nui kia tino tirohia mēnā he turuturu, me te tuhi anō hoki i te uara pēhanga, te huringa taumata wai rānei i roto i te wā kua whakaritea.
Tapu 5

Ka whakamahia ngā flange takirere noa mengā takirere pūrerehuaTe rahi o tetakirere pūrerehuaNā reira, he rerekē te flange i te flange takirere paerewa. He iti te diameter o roto o ētahi flange, ko te kōpae ia o te takirere pūrerehua he nui, ka kore e mahi tika te takirere, ka tuwhera mārō rānei, ka pakaru. Ngā Ine: Whakamahia te flange kia rite ki te rahi tuturu o te flange o te takirere pūrerehua.

Tapu 6

I te hanganga o te hanganga whare, kāore i rāhuitia ngā wāhanga kua whakauruhia, kāore rānei i tohua ngā wāhanga kua whakauruhia, ā, he iti rawa ngā kōhao kua tohua. Ngā Huanga: Mā te whao i te hanganga whare, te tapahi rānei i ngā pae rino kua pēhia ka pā ki te mahi haumaru o te whare i te wā e tāuta ana i ngā kaupapa whakamahana me te horoi. Ngā Mahi: Akohia ngā mahere whare mō te kaupapa whakamahana me te horoi kia āta, ā, whai wāhi atu ki te hanganga o te hanganga whare mā te rāhui i ngā kōhao me ngā wāhanga kua whakauruhia e tika ana mō te tāutanga o ngā paipa, ngā tautoko, me ngā whakairi. Tena tirohia ngā whakaritenga hanga me ngā whakaritenga hoahoa.

Tapu 7

Ina whakarewahia te paipa, ka kore te tūnga e anga ki waenganui, kāore he āputa i te tūnga, kāore te awaawa e kerihia mō te paipa matotoru te pakitara, ā, kāore te whānui me te teitei o te whakarewa e rite ki ngā whakaritenga hanga. Ngā Huanga: Nā te mea kāore te paipa i te pokapū, ka iti ake te whai hua o te tukanga whakarewa, ā, ka iti ake te āhua ngaio. Ina kore te whānui me te teitei o te whakarewa e tutuki i ngā whakaritenga, kāore he āputa i waenganui i ngā hoa, kāore te paipa matotoru te pakitara e keri i te awaawa, ā, kāore e taea e te whakarewa te whakatutuki i ngā whakaritenga kaha.
Ngā Ine: Whakatōkia he paipa matotoru te pakitara, waiho he āputa i ngā hononga, ā, whakaritea ngā paipa kia tū ki te rārangi pokapū ina oti ngā hononga te whakarewa. Hei tāpiri, me whakarewa te whānui me te teitei o te hononga whakarewa kia rite ki ngā aratohu.

Tapu 8

Ka tanumia te paipa ki runga i te oneone hukapapa me te oneone koretake kāore i rongoatia, ā, ka whakamahia ngā pereki maroke. Kāore hoki i te tika te tawhiti me te tūnga o ngā pou tautoko mō te paipa. Ngā Huanga: Nā te wiri o te tautoko, i kino te paipa i te wā e pēhia ana te oneone o te whenua whakakī, ā, me mahi anō, me whakatika. Ngā Mahi: Ehara i te mea tika te oneone koretake kāore i rongoatia me te oneone hukapapa mō te tanumanga o ngā paipa. Me piri te tawhiti i waenga i ngā pou tautoko ki ngā aratohu hanga. Hei whakaoti me te pumau, me whakamahi te moata sima hei hanga pou tautoko pereki.

Tapu 9

Ka whakapūmauhia te tautoko paipa mā te whakamahi i ngā pūtu whakawhanui, engari he ngoikore te hanganga o ngā pūtu, he nui rawa ngā kōhao, he mea whakairi rānei ki ngā pakitara pereki, ki ngā pakitara māmā rānei. Ngā Huanga: Kua piko te paipa, kua taka rānei, ā, he ngoikore te tautoko paipa. Me whiriwhiri ngā pūtu whakawhanui i ngā mea pono, ā, me tirotirohia pea ngā tauira hei tirotiro. Kaua te whānui o te kōhao e whakamahia ana hei whakauru i ngā pūtu whakawhanui e 2 mm te nui ake i te whānui o waho o ngā pūtu whakawhanui. Mō ngā whare raima, me whakamahi ngā pūtu whakawhanui.

Tapu 10

He poto rawa ngā pūtu hono, he iti rānei te whānui, ā, kāore i te tino pakari ngā āputa me ngā hiri e whakamahia ana hei hono i ngā paipa. Mō ngā paipa whakamahana, ka whakamahia ngā papa rapa, mō ngā paipa wai matao, ngā papa paparua, ngā papa piko rānei, ā, ka piri ngā papa āputa mai i te paipa. Ngā Huanga: Ka puta te turuturu nā te mea he wetekina, he pakaru rānei te hononga āputa. Ka piri te āputa āputa ki roto i te paipa, ka uaua ake te rere o te wai. Ngā Ine: Me piri ngā āputa me ngā hiri o te paipa ki ngā whakaritenga o te pehanga mahi hoahoa o te paipa. Mō ngā āputa āputa i runga i ngā paipa whakamahana me te wai wera, me whakamahi ngā āputa rapa asbestos; mō ngā āputa āputa i runga i ngā paipa tuku wai me te waikeri, me whakamahi ngā āputa rapa. Kaua tetahi wāhanga o te āputa āputa e toro atu ki roto i te paipa, ā, me pā tōna porowhita o waho ki te kōhao pūtu o te āputa. Kaua te pokapū o te āputa e whai papa piko, papa maha rānei. Ko te diameter o te pūtu e hono ana i te flange me iti iho i te 2 mm te nui ake i te kōhao o te flange, ā, ko te roa o te nati e kokiri ana i runga i te tokotoko pūtu me ōrite ki te haurua o te matotoru o te nati.
