4. Te hanga i te takurua, te whakamātautau pēhanga wai i te pāmahana i raro i te kore.

Te Huanga: Nā te mea kei raro iho i te kore te pāmahana, ka tere te tio o te paipa i te wā o te whakamātautau waipēhi, ka tio pea te paipa, ka ngatata hoki.

Ngā Mahi: Ngāna ki te whakahaere i te whakamātautau pēhanga wai i mua i te hanganga i te takurua, ā, tangohia te wai i roto i te paipa me te takirere i muri i te whakamātautau pēhanga, ki te kore ka waikura te takirere, ā, ka arahi pea ki te ngatata hukapapa.

5. Kāore i te kaha te flange me te gasket o te hononga paipa, ā, he poto, he angiangi rānei te whānui o ngā pūtu hono. Ka whakamahia te papa rapa mō te paipa wera, ka whakamahia te papa takirua, te papa piko rānei mō te paipa wai matao, ā, ka pakaru te papa flange ki roto i te paipa.

Ngā hua: kāore te hononga o te flange e piri, ahakoa kua pakaru, ka turuturu. Ka piki ake te ātete rere o te flange e piri ana ki roto i te paipa.

Ngā Inenga: Me tutuki ngā here paipa me ngā gaskets i ngā whakaritenga o te pēhanga mahi hoahoa paipa.

Me hanga ngā hiri o ngā paipa whakamahana me te wai wera ki te asbestos rapa; me hanga hoki te hiri o ngā paipa wai me te waikeri ki te rapa.

Kaua te arai o te flange e pakaru ki roto i te ngongo, ā, me porowhita te porowhita o waho ki te kōhao pūtu o te flange. Kaua he papa piko, he maha rānei ngā hiri e whakanohoia ki waenganui o te flange. Ko te whānui o te pūtu e hono ana i te flange me iti iho i te 2mm ki te whakarite ki te kōhao o te flange. Ko te roa o te nati e puta mai ana o te tokotoko pūtu me 1/2 o te matotoru o te nati.

6. Kāore e taea te whakamātau i te wai katia mō ngā paipa paru, wai ua, me te wai whakapūkara.

Ngā Huanga: Tērā pea ka turuturu, ā, ka ngaro pea ngā painga mō ngā kaiwhakamahi. He uaua te tiaki.

Ngā Whakatakotoranga: Me tirotirohia te whakamātautau wai kua kati, ā, me whakaae kia rite ki ngā whakaritenga. Me tanu ki raro i te whenua, ki te tuanui, ki waenganui i ngā paipa me ētahi atu paru huna, wai ua, paipa waiwhakapūmau, me ētahi atu, kia kore ai e turuturu.

7. Te whakatuwheratanga me te katinga o te takirere ā-ringa, te kaha nui rawa
Ngā hua: ka pā te kino māmā ki te takirere, ka pā te kino nui ki ngā aituā haumaru

Ngā Ine:

Ko te wira ringaringa, te kakau rānei o te takirere ā-ringa, he mea hanga kia rite ki te kaha o te tangata noa, me te whakaaro ki te kaha o te mata hiri me te kaha kati e tika ana. Nō reira, kāore e taea te whakamahi i ngā rīwhi roa, i ngā ringa roa rānei hei neke i te papa. Ko te hunga kua taunga ki te whakamahi i ngā kī, me tino tupato kia kaua e nui rawa te kaha, ki te kore ka ngāwari te pakaru o te mata hiri, ka whati rānei te wira ringaringa me te kakau. Whakatuwheratia, ka kati hoki te takirere, kia maeneene te kaha, kaua e kaha te pānga. Mō te takirere mamaoa, i mua i te whakatuwheratanga, me whakamahana i mua, me ārai hoki i te wai mātao, ā, i te wā e whakatuwherahia ana, me āta haere kia kore ai e puta te hama wai.

Ina tuwhera katoa te takirere, me huri te wira ringaringa kia paku whakahurihia, kia piri ai te miro i waenganui i ngā miro, kia kore ai e pakaru. Mō ngā takirere kākano tuwhera, kia maumahara ki te tūranga o te kākano ina tuwhera katoa, me te tūnga kati katoa kia kore ai e pā ki te pokapū mate o runga ina tuwhera katoa. Ā, he māmā hoki te tirotiro mēnā he noa te kati katoa. Mēnā ka taka te kōpae, ka uru rānei he paru nui ki waenganui i te hiri o te poro, me whakarerekē te tūranga o te kākano takirere ina kati katoa te takirere.

Ina whakamahia tuatahitia te paipa, he nui ake ngā poke o roto, ka taea te whakatuwhera paku i te takirere, ka taea te whakamahi i te rere tere o te reo hei horoi atu, kātahi ka kati mārire (kāore e taea te kati tere, kia kore ai e whara te mata hiri i ngā poke toenga), kātahi ka whakatuwhera anō, kia maha ngā wā ka whakahokia, horoia te paru, kātahi ka whakamahia ki te mahi noa. I te nuinga o te wā ka whakatuwherahia te takirere, tera pea ka piri te mata hiri ki ngā poke, ā, me horoi kia ma i te wā ka kati, kātahi ka kati ā-ture.

Mena kua pakaru, kua ngaro rānei te wira ringaringa, te kakau rānei, me hono tonu, ā, kaua e taea te whakakapi ki tētahi ringaringa pereti ngāwari, kia kore ai e pakaru te kakau takirere, kia kore ai hoki e tuwhera, e kati rānei, ka puta he aituā i te wā whakaputa. I muri i te katinga o te takirere kia whakamatao, kia mimiti ai ngā wāhanga takirere, me katinga anō te kaiwhakahaere i te wā tika, kia kore ai e waiho he tuitui pai i te mata hiri, ki te kore, ka rere te reo mai i te tuitui pai i te tere tere, ka ngāwari te pirau o te mata hiri.

Ki te kitea e koe he uaua rawa te mahi, tātarihia te take. Ki te tino piri te takai, ka taea te whakangāwari, pērā i te piko o te kakau takirere, me whakamōhio atu ki te kaimahi kia whakatika. Ko ētahi takirere, i roto i te āhua kati, ka whakawhanuitia te wāhanga kati e te wera, ka uaua te whakatuwhera; Ki te mea me whakatuwhera i tēnei wā, ka taea e koe te wetewete i te miro taupoki takirere i te haurua o te huringa ki te kotahi huringa, tangohia te ahotea o te kakau, kātahi ka tōia te wira ringaringa.
