1. ʻO ka valve by pass he mea pale ia no ka pahu nui e pale ai i ke kū'ēʻana o ka weheʻana mai ka nui loa ma muli o kaʻokoʻa puʻe nui ma waena o ka mua a me ke kua o ka pahu, aʻaʻole maʻalahi ka weheʻana o ka pahu, ma kahi nui ke anawaena o ke awa a i ole paipu paipu kiekie. Ma mua o ka weheʻiaʻana o ka pipeline kiʻekiʻe, hoʻomahaʻia ke kaomi ma o ka valve bypass e pale i ka hoʻokomo kokeʻana o ke kiʻekiʻe kiʻekiʻe a me ka hopena i ka pipeline ma lalo o ka valve. A i ʻole ʻoi aku ka nui o ka ʻokoʻa o ke kaomi ma waena o ka valve a nui loa ka torque. No ka pale ʻana i ka pōʻino o ka valve ma ka torque, e wehe i ka valve bypass e hoʻomaha i ke kaomi mua, a laila wehe i ka valve nui.

2. Hoʻohana ʻia ma ke ʻano he pipeline backup, ʻo ka pōmaikaʻi nui loa i ka wā e hāʻule ai ka valve nui a pono paha e mālama ʻia, hiki ke wehe ʻia e ka bypass valve circulation, a ʻaʻole pili i ka hana maʻamau.
