Ina pāngia ngā kiritaki e ngā "raru tohu", ko te tikanga ka hiahia rātou ki te whakahoki wawe i te mahi noa. Mā te whakarato i ngā mahi rapurongoā ka taea te whakahaere-ake ka taea te whakaiti i te pēhanga ki te Tautoko. Ko ngā mahi e whai ake nei:
- Tuatahi, tirohia te tāutanga me te hononga o te pūwero:
- Whakaūtia mēnā kei te piri tonu te taputapu tirotiro ki te paipa, ā, mēnā hoki kua whakakukūhia ngā tīwiri.
- Tangohia te pūwero, tirohia mēnā he paru hinu, he waikura rānei kei te mata e pā ana ki waenganui i te pakitara o waho o te paipa me te pūwero. I muri i te horoinga, pania anō te āpiti motuhake (me te matotoru o te 1-2mm, kia taurite te kapi i te mata o raro o te pūwero).
- Kātahi, tirohia te wāhi tāutanga:
- Mena kei te tata ki ngā tuke, ki ngā takirere rānei, ngana ki te neke i te pūwero ki runga, ki raro rānei, kia mōhio ai ko te wāhanga paipa tika ki runga he ≥ 10 ngā wā i te whānui o te paipa, ā, ko te wāhanga ki raro he ≥ 5 ngā wā i te whānui o te paipa. Āta karohia ngā wāhi he hononga paipa, he tauine nui rānei.
- Hei whakamutunga, tirohia ngā tawhā me te reo:
- Tomo ki te tahua manaaki, ka manatoko mēnā he rite ngā tawhā pēnei i te "diameter o roto o te paipa, te matotoru o te pakitara, me te rauemi" ki ngā āhuatanga tūturu (hei tauira, mā te whakauru hē i te DN100 hei DN80 ka puta he tohu rerekē).
- Whakaūtia mēnā kei te rere te wai i roto i te paipa i inehia (hei tauira, mēnā kua kati te takirere) ā, mēnā kei roto te pāmahana waenga i te awhe e tika ana o te mita rere (hei tauira, me whakamahi he ine pāmahana iti mō ngā pāmahana < -20℃).
