Ko te takirere kore-paerewa he momo takirere kāore he paerewa mahi mārama. Ko ōna tawhā mahi me ōna rahi he mea whakarite motuhake kia rite ki ngā whakaritenga o te tukanga. Ka taea te hoahoa me te whakarerekē noa me te kore e pā ki te mahi me te haumaru. Heoi, kei te whai tonu te tukanga miihini i ngā whakaritenga e tika ana o te paerewa ā-motu.

Me whai whakaaro te hoahoa o ngā takirere kore-paerewa ki te whaitake me te whaihua o te katoa. Haunga te whakawhirinaki ki ngā ariā tuku iho, me nui ake te rangahau me te whanaketanga auaha mō te hoahoa. Nō reira, ko te tikanga, he hunga rangatira kei roto i te umanga hei whakaoti i ngā mahi rite, ā, ka tukuna e ngā miihini ngā tuhi i muri i te otinga o te hoahoa.

Ko ngā momo takirere kore-paerewa kua wehea ki te raupapa takirere para (katia penstock me te takirere flap) me te raupapa takirere whakarewa (katia pūrerehua hau, takirere keti reti, takirere mōhiti, takirere tuku pungarehu, me ētahi atu)
