Fa'asa'o fa'asaga i le samala mamafa
Valau siaki fa'asagama le samala mamafa
Fa'aititia le samala vai ma le tafe,
lelei mo paipa ma nofoaga pamu.
O lenei ituaiga valve e masani ona faʻaaogaina i le pamu o le faʻaogaina o vai faʻapisinisi ma otaota e togafitia ai otaota e puipuia ai le toe foʻi mai o le ala i le laina paipa.Otometi ona aveese samala fa'aleaga vai ina ia mautinoa e le'o fa'aleagaina le pamu vai ma paipa.
O lenei alatoto e masani lava ona aofia ai le tino o le valve, o le valve disc, o se masini pa'u ma le micro-regulating valve.
