Damage Pipes — Can Caustic Soda

The danger caustic soda poses depends largely on what your pipes are made of.

If a severe clog blocks the drain, the caustic soda solution will sit in one spot (usually the P-trap under the sink). can caustic soda damage pipes

Standard PVC and ABS cements contain fumed silica to thicken the adhesive. Caustic soda chemically dissolves this silica, eating away the structural bond and causing joint failures. The danger caustic soda poses depends largely on

Plastic Pipes (PVC and ABS) Caustic soda chemically dissolves this silica, eating away

The extreme heat from the exothermic reaction easily surpasses the safe operating temperature of household plastics. This causes PVC pipes to soften, sag, or warp, permanently restricting wastewater flow.

It converts fats, grease, and cooking oils into water-soluble soap.

Caustic soda is a highly concentrated alkaline solution that can dissolve organic materials, such as grease, fat, and proteins. It's often used to:
