You have seen it at some point; that moment when somebody takes something from the toilet and drops in the bathroom sink. It makes you cringe, or at least, it should. When you go to clean a drain or clear a clog in either your toilet or your sink, are you keeping tools for these two fixtures separate? If you do not, you should, and here is why.
A Toilet Plunger and Toilet Auger Are Too Big for the Sink
Seriously, if you are using a toilet plunger to plunge a sink, you can do far more damage than good. The toilet plunger has greater suction power, which is why it is effective on the toilet. They make smaller plungers for sink drains so that not too much suction power is yanking on the sink drain. If you use a toilet plunger on the sink drain rather than a sink plunger, you can cause damage to the plumbing under the sink and even farther down the pipeline.
Likewise, a toilet auger has far too large a coiled head for a sink drain. Even if the head does fit the drain and the pipe (which would be highly unusual), you would be grinding and grating the inside of the plastic pipe or scraping the inside of a metal pipe. Neither of that is good because it slices up plastic pipes and scrapes rust and crud off the metal pipes. That is why they have sink augers. The sink augers fit nicely, grab clogs without damaging the pipes, and slide in and out of the sink pipes easily.
You Are Cross-Contaminating
It is enough to make your skin crawl. Let's pull fecal matter out of the toilet drain and transfer it to the sink. Then brush your teeth or care for your contact lenses later in the same sink after you accidentally drop either into the sink bowl. Unless you are of the mind that remembers to bleach the bathroom sink after using a toilet tool on the sink drain, you are putting fecal matter in your mouth or in your eyes. Yuck. Keeping the toilet and sink drain tools separate ensures that you are only contaminating the sink with sink germs.
If Your Plumber Has Separate Tools, Why Not You?
Plumbers have separate tools for clearing and cleaning drains. They already know about cross-contamination of germs and damages you can inflict on your sink with toilet tools. If they have separate tools for the sink and toilet, so should you.
