If you use them as directed, chemical drain cleaners may help to clear a partially clogged drain.
But because they’re so powerful, we suggest using them as a last resort.
So, yes, chemical drain cleaners can cause damage to your pipes, especially when:
- You have older, weak metal pipes
- You use them incorrectly with plastic pipes
- You use it on a completely blocked drain
You see, because they produce heat, chemical drain cleaners can warp or damage softer pipes like plastic and older metal piping.
