Is liquid fire drain cleaner safe for PVC pipes?

Liquid fire drain cleaners, which typically contain harsh chemicals like sodium hydroxide, can be damaging to PVC pipes. While they may effectively clear clogs, prolonged exposure or misuse can lead to pipe degradation or even leaks. It's advisable to use milder alternatives specifically labeled as safe for PVC or consult a professional plumber for safe drainage solutions. Always read the product label for compatibility with your Plumbing materials.
