Ko tēnei ka whakapai ake i te kaha, te manawa, te āwe o te pakanga, te āwe o te whakapā, me te āwe o te makariri o ngā pīpoi PVC.
Kei te tino pai ake te mahi ake o te mōweo hou o ngā pīpoi i huihui ai tēnei tikanga i ngā pīpoi PVC-U noa, ka taea ai te whakamāmā i ngā rāwau rawa, whakaiti i ngā utu, me te whakapai ake i te mahi whānui o te pīpoi. I te wā kotahi, ko ngā utu hanga me te whakauru i te pīpoi he iti ake.

Ko te mea nui ka whakapai ake i te kaha, te kaha pakari, te kaha whakatū ki te takirua, te kaha whakatū ki te mamae, me te kaha whakatū ki te rakihi o ngā pīpoi PVC.
• Ko te mahi a te momo hōwai hou i whiwhi ai tēnei tikanga he nui ake i te PVC-U tūhono, ka taea te penapena i ngā rākau mātai, te heke i ngā utu, me te whakapai ake i te mahi whānui o te hōwai. I te wā kotahi, he iti ake ngā utu hanga me te whakauru i te hōwai.
