You're brushing your teeth or rinsing dishes, and the sink starts filling up with water that won’t go down. That’s when you hear a common tip: “Just pour boiling water down the drain!” But does it work? Let’s break this down and see if boiling water can fix a clog, or if it’s just a quick trick that doesn’t do much. If you’re dealing with stubborn drain problems, it might be time to call a plumber. Companies like Mr. Rooter Plumbing often help people who have tried DIY methods without much luck.
Before we can say “true” or “false,” we must consider what is clogging the drain. Boiling water works best on certain types of blockages, like:
If the clog is made of these softer, meltable materials, boiling water might do the trick. The hot water can melt grease and wash away soft debris, so it’s sometimes recommended as a first step in clogged drain cleaning.
But here’s the thing—boiling water doesn't help much if your clog is made of hair, plastic-like buildup, or a small toy someone accidentally flushed.
The answer? Sometimes! It depends on the type and size of the clog.
Let’s say your bathroom sink is draining slowly, and you think it’s due to soap residue. Carefully pouring a kettle of boiling water down the drain in short bursts might clear it up.
But if your drain is completely blocked and water is backing up fast, that’s a bigger problem. In that case, you’ll probably need a plumbing service to snake the drain or inspect it with a camera.
Mr. Rooter Plumbing often recommends using boiling water as a safe, chemical-free way to try breaking up light clogs before reaching for harsher tools.
While this method is simple, it’s not without risks. Not all pipes can handle boiling water, especially if they’re made from:
Boiling water can cause these pipes to warp or even burst, leading to a bigger problem. In this case, calling a plumber might be your only option.
Also, never pour boiling water into a sink with a porcelain bowl if it's empty and cold. The sudden temperature change could crack the sink.
If you want to try using boiling water safely, here’s how:
If this doesn’t help, you’re probably dealing with a deeper issue — and that’s where a plumbing service comes in handy.
