Ina tae ki ngā mahi paipa me ngā mahi motuka, he mea nui te whiriwhiri i te rawhi tika. E rua ngā kōwhiringa rongonui ko ngā rawhi PEX me ngā rawhi ngongo taringa-kotahi. Ahakoa e whakamahia ana ngā rawhi e rua hei whakau i ngā ngongo me ngā paipa, he rerekētanga matua kei waenganui i ngā mea e rua. I roto i tēnei pou rangitaki, ka tūhuratia e mātou ngā rerekētanga i waenganui i ngā rawhi PEX me ngā rawhi ngongo taringa-kotahi, me ō rātou whakamahinga me ā rātou mahi.

Ko te rerekētanga matua i waenga i ngā rawhi PEX me ngā rawhi ngongo taringa-kotahi ko tō rātou hoahoa me te whakamahinga i whakaarohia. Ko ngā rawhi PEX, e mōhiotia ana ko ngā rawhi PEX kowiri tira, he mea hanga motuhake hei whakau i te paipa PEX ki ngā hononga. He mea whakamahi noa i roto i ngā mahi paipa, inā koa mō te hono i te paipa PEX ki ngā hononga parahi, polyethylene rānei. Ko ngā rawhi PEX he mea hanga ki te kowiri tira, ā, he hoahoa ahurei e taea ai e rātou te whakau pono ki ngā paipa PEX me te hanga i tētahi hiri ā-wai.

I tētahi atu ringa, ko te rawhi ngongo taringa-kotahi, e mōhiotia ana ko te rawhi Oetiker, he rawhi whānui ake e whakamahia ana hei whakau i ngā ngongo me ngā paipa i roto i ngā momo mahi. He mea whakamahi noa ngā rawhi ngongo taringa-kotahi i roto i ngā mahi motuka me ngā mahi ahumahi hei whakau i ngā ngongo rapa, ngā ngongo silicone, me ētahi atu momo paipa. He mea hanga ki te kowiri tira, he kotahi te taura, he whitiki rānei e piri ana ki te ngongo, ki te paipa rānei hei whakarato i te hiri haumaru.

Ko te hanganga, he nui ake ngā rawhi PEX, ā, he whānui ake te whakatuwheratanga i ngā rawhi ngongo taringa-kotahi. Mā tēnei ka taea e rātou te whakauru i ngā pakitara paipa PEX matotoru ake, ā, ka kaha ake te pupuri. Ko ngā rawhi ngongo taringa-kotahi, i tētahi atu taha, he mea hanga kia iti ake, kia māmā ake hoki, kia pai ai mō ngā mahi e iti ana te wāhi.

Mō te tāutanga, me whakamahi he taputapu kume PEX mō ngā rawhi PEX hei whakau i te rawhi ki te paipa me ngā hononga. Ka pēhia e tēnei taputapu motuhake te pēhanga e tika ana hei hanga i tētahi hiri piri, kia kore ai e turuturu te hononga. Ko ngā rawhi ngongo kotahi-pū, i tētahi atu taha, ka tāutahia mā te whakamahi i tētahi takirua rākau kume, e pēhi ana i ngā taringa, i ngā whitiki rānei o te rawhi kia mau ai.

Mō ā rātou whakamahinga, he mea hanga motuhake ngā rawhi PEX hei whakamahi me ngā paipa PEX i roto i ngā mahi wai, ko ngā rawhi ngongo taringa-kotahi he maha ake ngā whakamahinga, ā, ka taea te whakamahi me ngā momo rauemi ngongo me ngā paipa. Hei tāpiri, he mea hanga ngā rawhi PEX kia tu atu ki ngā pēhanga me ngā pāmahana teitei, kia pai ai mō te whakamahi i roto i ngā pūnaha wai wera me te wai matao.

Hei whakamutunga, ahakoa ka taea te whakamahi i ngā rawhi PEX me ngā rawhi ngongo taringa-kotahi hei whakau i ngā paipa me te ngongo, he rerekētanga matua kei waenganui i ngā mea e rua. Kua hangaia ngā rawhi PEX hei whakamahi me ngā paipa PEX i roto i ngā mahi paipa, ko ngā rawhi ngongo taringa-kotahi ia he maha ake ngā whakamahinga, ā, ka taea te whakamahi i roto i ngā momo mahi. Mā te mārama ki ngā rerekētanga i waenganui i ēnei rawhi ka āwhina i a koe ki te whiriwhiri i te rawhi tika mō ō hiahia.
