He taputapu purenga te pouaka Hepa me te wae tātari hau e whakamahia ana i roto i te rūma ma hei tātari i ngā matūriki puehu i te hau kia tutuki ai ngā whakaritenga horoi mō te whakaputa hua. Ka pania ngā mata o waho o ngā pouaka e rua ki te rehu hiko, ā, ka taea te whakamahi i ngā pereti maitai hurihuri-matao, ngā pereti maitai kore waikura me ētahi atu anga o waho. Ka taea te whakarite i ngā mea e rua kia rite ki ngā whakaritenga motuhake a te kiritaki me te taiao mahi.
He rerekē ngā hanganga o ngā hua e rua. Ko te pouaka Hepa he pouaka, he pereti horapa, he putanga flange, me te tātari hepa, ā, kāore he taputapu hiko. Ko te wae tātari pā he pouaka, he flange, he pereti ārahi hau, he tātari hepa, me te pā, me te taputapu hiko. Whakamahia he pā tohanga tōtika-teitei. He roa te ora, he iti te haruru, kāore he tiaki, he iti te wiri, ā, ka taea te whakarite i te tere o te hau.
He rerekē ngā utu o ngā hua e rua i te mākete. He nui ake te utu o te FFU i te pouaka hepa, engari he tino pai te FFU mō te whakakotahi ki tētahi raina whakaputa tino ma. E ai ki te tukanga, kāore e taea te whakamahi hei wae kotahi anake, engari ka taea hoki te hono i ngā wae maha i roto i te raupapa hei hanga i tētahi raina huihuinga akomanga 10000. He tino ngāwari te tāuta me te whakakapi.
E whakamahia ana ngā hua e rua i roto i te rūma ma, engari he rerekē te tikanga horoi o te rūma ma. Ko ngā rūma ma o te akomanga 10-1000 he mea whakamahi i te wae tātari hau, ā, ko ngā rūma ma o te akomanga 10000-300000 he mea whakamahi i te pouaka hepa. Ko te whare horoi he rūma ma māmā i hangaia mō te huarahi tere me te watea. Ka taea anake te whakamahi i te FFU, ā, kāore e taea te whakamahi i te pouaka hepa me te kore he taputapu hiko.
