Ko tetohu rere waika whakamahia mo te punaha pupuhi a-ringa. Ka taea te whakauru ki runga i te putorino wai matua, i te paipa wai pae whiti ranei hei whakaatu i te tohu hiko o te rere wai ki tetahi waahi iti me te waahi iti. Ka taea te tuku i te tohu hiko ki te pouaka mana hiko, ka taea hoki te whakamahi ki te timata i te huringa mana o te papu ahi.
Ngā tūpato mō te tāuta me te whakamahi:
1. Ko te tohu rerenga wai me whakanoho whakapae ki runga i te paipa o te punaha, kaua hoki e whakauruhia ki te taha, ki runga ranei ki raro kia kore ai e pa ki te maaramatanga o te tohu rerenga wai.
2. Ko te putorino e hono ana i te tohu rerenga wai me whakarite kia kaua e iti iho te roa o nga paipa tika o mua me muri i te 5 wa o te diameter paipa. I te wa e whiriwhiri ana i te tohu rerenga wai, me whiriwhiri kia rite ki te diameter ingoa o te paipa me te tepu tawhā hangarau.
3. Me aro ki te ahunga o te rere o te wai i te wa e whakauruhia ana, a kaua e whakahaerea te whakaurunga ki te huarahi tapahi.
4. Ko te wa roa o te tohu rerenga wai ka taea te whakatika i te wa e wehe atu ai i te wheketere, a ko te awhe whakatikatika ko 2-90s.
Ko te tiimata o te papu rehu kaore i te tiimata tika ma te tohu tohu me te tohu rere wai. Ko te pana pehanga me timata ma te ringa. Ko te tohu o te pehanga pana tohu takirere me te tohu rere wai i runga i temākū whakaoho takirereme tuku ki te ope whakaoho o te ope whakaoho. Ka whiwhi te kaihautu whakaoho i te tohu mahi o te tohu rere wai me te tohu pana pehanga. Ko te maataki hononga whakahau a-ringa ka tiimata te tohu tohu tohu ka whakamahia noa hei tohu i te mana o te huringa takirere, kaore he mahi ki te papu wai.
Ko te tohu pana pehanga ka whakahaerehia me te whakaputa i nga huarahi e rua. Ka tiimata tika te whare papu i te papua ka tukuna atu ki te kaihautu whakaoho i te pokapu whakahaere ahi mo te whakaoho. Mena kaore i te honohia te tohu tohu mana mamao, kaore e taea te whakaatu i te whakatuwheratanga me te kati o te waahi. Ki te katia te takirere, kare rawa e whakaatuhia ki te kaihautu whakaoho.
Mena kaore i te hono te tohu rerenga wai, kaore e taea te tohu he wai e rere ana i roto i te paipa, kaore hoki e tohu kua timata te papu wai ki te hono.
Na reira, e hiahiatia ana i roto i te whakatakotoranga me hono raua e rua ki te kaihautu whakaoho matua kia whiwhi i te tohu mahi o te tohu rere wai me te tohu whakahuri pehanga, me te whakahau a ringa i te hononga ki te timata i te papu.
Ko te mahi o te tohu rerenga wai ko te whakaatu i te waahi ahi i roto i te waa, a ko te tohu tohu ko te whakaatu i te mana whakatuwhera o te paera.
Mena kaore he waea, me korero ano te whakamarumaru ahi. Kaore he take ki te mataku. Ko tetakirere pūrerehua tohuka aroturuki noa i te tohu whakatuwhera me te kati. He mea nui ake te tohu rerenga wai. Ko etahi o nga hoahoa miihini kaore i te whakarite kia kore he mahi he. Ko te arorau timatanga o te papu rehu kua whakaritea hei paera whakaoho me te pana pehanga. I tua atu, ko te mahi ko te timata i te papu. I te wa e whakaaetia ana te ahi, he pai ake te tuku korero ki te kaihautu mena ka kaha te mahi o te tohu rerenga wai i muri i te whakatuwheratanga o te taputapu whakamatautau wai, He pai ake te aro turuki me te waahanga whakauru.
Ina he wai e rere ana i roto i te tohu rerenga wai, ka kati tana whakapiri awhina, katahi ka whakahokia te tohu ki te kaihautu ma te waahanga. Inaianei kua kore e tika kia uru atu ia ki te hono o te papu rehu. I te wa e kati ana te tohu tohu, ka whakahokia he tohu ki te kaihautu na roto i te waahanga hei tohu kua kati te tohu.
