Ko te "Maamaa, Te Whakahoutanga, Te Maamaa, me te Maamaa" ko te whakaaro tonu o ta maatau whakahaere mo taua wa roa ki te whakaputa tahi me nga kaihoko mo te tauutuutu me te painga tahi mo nga Kaihokohoko Hainamana H71 Series American Standard Wafer Lift Check Valve, Ko matou, me te tino ngakau nui me te pono, e pai ana ki te whakarato ki a koe nga ratonga tino tika me te anga whakamua me koe ki te hanga i te ao marama.
Ko te "Te pono, te auahatanga, te kaha, me te kaha" ko te whakaaro tonu o ta maatau whakahaere mo taua wa roa ki te whakaputa tahi me nga kaihoko mo te tauutuutu me te painga mo tetahi.Haina Pūrererere Valve,Haina Hikina Taki takirere,Aratau taraiwa maha , kei te titiro whakamua matou kia nui ake te mahi tahi me nga kaihoko o tawahi i runga i nga painga tahi. Ka whakapau kaha matou ki te whakapai ake i a matou otinga me a matou ratonga. Ka oati ano matou ki te mahi tahi me nga hoa pakihi ki te hiki i to maatau mahi ki te taumata teitei me te tiri angitu. Tena koe ki te toro atu ki to maatau wheketere.
E tohu ana te taki taki hiki te takirere ka whakatuwhera aunoa me te kati i te kōpae i runga ano i te rere o te reo ake hei aukati i te rerenga o te reo, e mohiotia ana ko te taki taki, te taki kotahi-ara, te rewharewharewharewha, me te pehanga o muri. Ko te taki taki he takirere aunoa. Ko tana mahi nui ko te aukati i te rerenga o te reo, te papu whakamuri me te taraiwa motuka, me te tuku i te reo ipu. Ka taea hoki te whakamahi i nga maataki i roto i nga raina paipa hei tuku i nga punaha awhina ka piki ake te pehanga ki runga ake i te pehanga o te punaha. Ka taea te wehea nga taki taki ki nga piu taki taki (hurihuri i runga i te pokapū o te kaha) me te hiki taki taki (neke haere i te tuaka).
