I te tau 1921, i hangaia e te Kaihautū o mua o te Ope Taua Moana o te Karauna, a Lumley Robinson, tētahi taputapu māmā noa iho, ā, ka tere tonu te noho hei tētahi o ngā taputapu tino pono, tino whānuitia hoki te whakamahinga o te ao. Kei te kōrero tātou — ko te tikanga — mō te rawhi ngongo iti. Ka whakamahia ēnei taputapu e ngā kaimahi paipa, ngā mekanika, me ngā tohunga whakapaipai whare mō ngā mahi maha, engari he tino whai hua i roto i ngā āhuatanga paipa ohorere.

Ina tīmata te turuturu ohorere o te paipa, me tere te mahi mena kei te pirangi koe ki te ārai i ngā kino nui o te wai. Ā, he maha ngā whakatikatika tere, DIY ka taea e koe te whakawhirinaki ki te whakatika i ngā paipa pakaru i roto i tō whare. Engari ki te kore he rawhi ngongo i roto i tō pouaka taputapu, e kore e taea e koe te neke atu i te taahiraa tuatahi: whakawetohia te wai.

Arā, ki te hiahia koe ki te whakatika i ō paipa i roto i tētahi āhuatanga ohorere, me whakarite e koe ētahi herenga ngongo. Ā, kia haumaru ai, me whai koe i tētahi o ēneingā rawhi ngongo whakarerekētangarānei ētahi momo rawhi ngongo rerekē kia rite ai koe mō ngā mea katoa. Nā reira, me pēhea e taea ai e koe te whakamahi i ngā momo rawhi ngongo rerekē hei whakaora i te paipa e turuturu ana? Nā te kaha tonu o te kume o ngā rawhi ngongo ki ngā taha katoa o te ngongo, o te paipa rānei, ka taea e rātou te whakau i ngā pātaki ki tōna tūranga. Ahakoa kāore e hiritia te paipa mō ake tonu atu, ka taea e ia te whakarato i te otinga tere e hiahiatia ana e koe hei whakaora anō i tō wai.

• Mō ngā kōhao tino iti, takaihia te rīpene hiko huri noa i te paipa kia maha ngā wā. Ina kapi katoa te kōhao, ka taea e ngā rawhi ngongo iti te whakarite kia piri pai (ahakoa he rangitahi).

• Mō ngā turuturu nui ake, rapua he wahi rapa hei taupoki i te kōhao. Ka taea te whakamahi i tētahi ngongo māra tawhito mēnā he uaua. Tapatapahia noa te rapa, te ngongo rānei kia whānui hei taupoki katoa i te kōhao, kātahi ka tapahia kia roa ake. Ko te mea pai, me toro atu te pāti kia torutoru inihi ki ngā taha o te kōhao. Kātahi, whakamahia he rawhi ngongo whakarerekē hei whakau i te pāti ki tōna tūranga.

Kia maumahara: Ina whakamahia e koe ngā rawhi ngongo hei āwhina i te tāmi me te whakatika i ngā paipa turuturu, pakaru rānei, me whakakapi tonu te paipa i te mutunga. Engari mō te mahi whakatika tere me te ngāwari, kāore he mea e whai hua ake ana i te rawhi ngongo whakarerekē watea.
