Ka tīmata te tukanga hanga mā te hono i ngā rīpene maitai mai i te pito ki te pito mā te whakamahi i te whakarewa pewa kotahi, waea rua rānei i raro i te wai. Mā tēnei tukanga ka whakarite kia pai te hononga i waenga i te pane me te hiku, ka whakarei ake i te hanganga o te paipa. Muri iho, ka hurihia te rīpene maitai kia rite ki te āhua ngongo. Hei whakapakari ake i te paipa, ka whakamahia te whakarewa pewa aunoa i raro i te wai mō te whakarewa whakatika. Ka tāpirihia e tēnei tukanga whakarewa he paparanga pakari anō, ka taea ai e te paipa te tu atu ki ngā āhuatanga taiao uaua.

Kua hangaia ngā paipa SAWH kia tutuki ai ngā whakaritengaEN10219ngā paerewa, e whakarite ana i tō rātou hototahitanga ki ngā momo tono ahumahi. Kei te wātea mai i te 6mm ki te 25.4mm ngā matotoru o te pakitara, he pai ēnei paipa mō ngā momo kaupapa. Ahakoa he whanaketanga hanganga, he kawe hinu me te hau, he kaupapa hanga rānei, ka whakaratohia e SAWH Pipes ngā otinga pono, whai hua hoki.
