FAQ
Q: Is boiling water safe for unclogging drains?
A: In metal-only systems, it might be okay occasionally — but in homes with PVC or mixed piping, it can lead to long-term damage. Use enzymatic drain cleaners or baking soda/vinegar instead.
Q: Can I pour hot water from pasta or cooking down the sink?
A: Let it cool slightly before pouring. And never pour it if it’s oily or starchy — those particles can gum up your pipes.
Q: What’s the best way to remove odors from the drain?
A: Try a mix of lemon juice and baking soda, followed by warm water. You can also grind citrus peels in the disposal if you have one.
Q: How do I know if my pipes are damaged from heat?
A: Signs include slow drainage, leaks, bubbling under the sink, or warped pipe surfaces. If in doubt, consult a plumber.
Q: Are there any benefits to using boiling water at all?
A: It’s great for sterilizing tools, cleaning surfaces, or loosening grime in cookware — but not for drains.
