When a sink or drain is blocked, it is usually because of a build-up of fats and grease. The presence of sodium hydroxide, either as an ingredient in a cleaner or as a home-made aqueous solution, kick-starts saponification and converts these pesky fats into soaps. The soap is then easily dissolved and removed by water.
Does sodium hydroxide harm pipes?
Lye is an incredibly basic, alkaline metal compound (sodium hydroxide), often used as a soap for cleaning purposes. This caustic can deteriorate metal piping and, in some forms, as when mixed with an aluminum compound to increase its cleaning power, can easily generate enough heat to warp or deform PVC piping.

Can sodium hydroxide melt PVC?
In the case of sodium hydroxide, or lye, the heat may be enough to raise the temperature over the boiling point. Although the chemicals themselves are extremely caustic, it’s the heat generated by the chemical reaction that causes PVC pipes to soften and melt.
Does sodium hydroxide damage PVC?
see less In general it is safe to use on PVC pipe. The active ingredient in Drano is sodium hydroxide (lye) and it doesn’t react chemically with the plastic pipe. However, when the drano is mixed with water you get an exothermic reaction that can melt some plastics from the heat released.
How does sodium hydroxide dissolve?
To make 1 M NaOH solution, you have to dissolve 40.00 g of sodium hydroxide pellets in 250 mL distilled water and then make up the solution to 1 liter. Weigh 19.95 gm of NaOH pellets & dissolve them in half liter(500ml) of distilled water water, what you will be having now is 1M NaOH solution.
