Master plumber here. I wish you didn't pour it into a PVC pipe, as muriatic acid can damage it. What drain pipe are you unclogging exactly, is it for toilet, ****** or sink? Do you have an idea what caused the drain to clog?
Try to wash the pipe poured with muriatic acid with by streaming it with water, then pour liquid sosa unto it. Hope this helps.
@zero_o_clock..tingin ko pvc pip3s lang sya. pero ung tubig sa bathroom drain ay still pero bumababa nmn kaso matagal at nag o-overflow pag sya pag nag buhos ng tubig sa lababo at sa toilet bowl
Liquid sosa/drain cleaner na malapot boss yung iniiwan sa gabi. Tapos sa umaga mo na babanlawan ng tubig. Basta sure ka na hindi plastic yung bumara basta organic bumara kaya yun like hair, nails, oil, feces, etc. Kung plastic hindi ko lang sure kung ano dapat ilagay.
