A：Ka whakaratohia e te miihini hiko hau he puna wera mo te tukatuka, te whakaputa me te whakamahana o nga hinonga ma te whakaputa i te mamaoa wera nui. Engari i te wa ano, kaua e wareware ki te whakaurunga o te kohua me te aro nui ki nga taputapu paipa. Kaore tenei e pa ki te ahua katoa o te kohua, engari he nui te paanga ki te mahi pumau i te waahanga o muri mai. Na, me pehea te whakauru i te mita o te miihini hiko hau?
Ko te ine i waenga i te ine taumata wai me te raina taumata wai noa o te pahū miihini mamaoa hau kei waenga i te 2mm. Me tohu tika te taumata wai teitei, te taumata wai iti me te taumata wai noa. Ko te ine wai me whai i te rewharewha me te paipa wai e hono ana ki tetahi waahi haumaru.
Me whakanoho te ine pehanga ki tetahi waahi e pai ana mo te mataki me te horoi, me tiaki mai i te wera nui, te mīti me te wiri. Ko te ine pehanga hiko hiko me whakauru ki te mahanga mamaoa, me whakanoho he tikaokao ki waenga i te ine pehanga me te mahanga mamaoa kia pai ai te rere o te paipa me te whakakapi i te ine pehanga. Me noho he raina whero ki te mata o te waea e tohu ana i te pehanga mahi o te kohua.
I muri i te whakaotinga o te whakamatautau hydrostatic o te miihini hiko hau, me whakauru he waahi haumaru, me te whakatikatika i te pehanga mahi o te waahi haumaru ka puta te ahi tuatahi. Me whakauru te puera haumaru ki te putorino ngongo, me arahi ki te waahi haumaru me te whai waahi whitinga kia pai ai te ngenge. Ko te raro o te putorino o te putorino haumaru me hoatu he paipa whakaheke i te waahi haumaru i te whenua, a kaore e whakaaetia kia whakauruhia nga putorino ki runga i te putorino me te paipa whakaheke.
Me whakaurua ia kaihanga mamaoa hau ki te paipa parakaingaki motuhake, me whakaiti te maha o nga tuke kia pai ai te rere o te para parakaingaki, me hono atu ki tetahi waahi haumaru o waho. Mēnā he maha ngā kōhua e tiritiri ana i te putorino pupuhi, me whai tikanga haumaru. I te wa e whakamahi ana i te taika roha pehanga, me whakauru he paera haumaru ki runga i te tank pupuhi.
