Ngemibhobho enezivalo ezivaliweyo, sicebisa ukuba uthenge umbhobho kunye nevalve yokuvala ngokwahlukeneyo, emva koko uzifakele kunye. Uncedo loku kukuba kuqala zibiza kakhulu. Nangona zingamalungu amabini, zibiza kakhulu xa kuthelekiswa nomlomo wombhobho onesivalo esivaliweyo xa sisonke. Ezantsi, kuba uyilo lwemilomo yemilomo ikakhulu lujonga umphumo wokutshiza, ke zonke izakhiwo zangaphakathi ziyilelwe ukufikelela kwisiphumo sokutshiza esingcono. Ukuba isixhobo sevalve siyilelwe kwisiphelo samanzi, uyilo lwangaphakathi lwemilomo luya kutshatyalaliswa. Umbhobho kufuneka wenziwe ngokutsha, ongonyusi kuphela iindleko zoyilo, kodwa ukonyusa nexabiso lokuvelisa. Enye inzuzo kukuba umlomo kunye nesivalo sokuvala zingamacandelo amabini. Enye yazo yonakele kwaye inokutshintshwa ngokuthe ngqo. Ukuba umlomo kunye nesivingco esivaliweyo siyilelwe iphelele, enye yazo yonakele, kwaye iseti yamalungu kufuneka itshintshwe.

Ukuba umlomo uqhutywa ngamanzi etephu, ungakwenza oko ngokupheleleyo. Kodwa ukuba uqhutywa yimpompo yamanzi, ngaphambi kokufaka ivalve evaliweyo, kuya kufuneka ujonge ukuba ingaba impompo yamanzi inesixhobo sokuziva ngoxinzelelo. Ukuba akukho sixhobo sive ngoxinzelelo, ungasicima isitopu Emva kwesivingco, impompo yamanzi iyaqhubeka nokubaleka, enokuqhushumba umbhobho wamanzi okanye igqithe kuxinzelelo lwempompo yamanzi, isiphumo somonakalo kwimpompo yamanzi.
Ngolwazi oluthe kratya lobuchwephesha malunga nemilomo enezivalo ezivaliweyo, nceda ukhululeke ukunxibelelana nathi.
