Cov yam ntxwv:
1. Lub valve no tuaj yeem tso pa tawm kom txo qhov tsis kam hauv cov kav dej.
2. Nws tuaj yeem nqus cua tau sai thiab sai kom tiv thaiv cov yeeb nkab tawg thaum muaj qhov siab tsis zoo hauv cov yeeb nkab.
3. Cov khoom siv ntawm lub pob ntab yog cov hlau tsis xeb kom paub tseeb tias lub neej ua haujlwm ntev.
