Ko ngā rawhi puna he mea hanga i tētahi rīpene maitai puna, he mea tapahi kia whaiti te pūwero o tētahi taha ki waenganui i te pito, ā, kia rua ngā pūwero whaiti ki tētahi taha. Kātahi ka pikohia ngā pito o ēnei pūwero ki waho, ā, ka hurihia te rīpene hei hanga i tētahi mowhiti, me ngā ripa pūwero e hono ana.

Hei whakamahi i te rawhi, ka pēhia ngā ripa e kitea ana tetahi ki tetahi (mā te whakamahi i ngā pliers), ka whakanuia te diameter o te mowhiti, kātahi ka nekehia te rawhi ki runga i te ngongo, ki tua atu i te wāhanga ka eke ki te tarau. Kātahi ka whakauruhia te ngongo ki runga i te tarau, ka whakawhanuitia anō te rawhi, ka nekehia ki runga i te wāhanga o te ngongo ki runga i te tarau, kātahi ka tukuna, ka pēhia te ngongo ki runga i te tarau.

Kāore i te maha ngā whakamahinga o ngā here o tēnei hoahoa mō ngā pēhanga teitei, ngā ngongo nui rānei, nā te mea he nui rawa te rino e hiahiatia ana hei whakaputa i te kaha here, ā, kāore e taea te whakamahi noa i ngā taputapu ā-ringa. He mea whakamahi noa ēnei mō ngā ngongo pūnaha whakamatao motuka he maha inihi te whānui, hei tauira, mō te nuinga o ngā Volkswagen whakamatao-wai.

He tino pai ngā rawhi puna mō ngā wāhi kuiti, ngā wāhi whakararuraru rānei e hiahiatia ana ngā taputapu whakakīkī mai i ngā koki whaiti, kāore pea e taea te uru atu ki ētahi atu momo rawhi. Nā tēnei kua tino rongonui rātou mō ngā mahi pēnei i ngā wāhi miihini motuka me te whakau i ngā hononga titi i roto i te whakamatao wai PC.
