Why Snaking Isn't Always The Best Solution
There are many drain cleaning methods, each with its pros and const. For example, there are chemical drain cleaners, plungers, and augers (for snaking blocked drains). Most people swear by one or the other, but it is never a good idea to rely on one method for every time you have a clogged drain. For example, here are some of the reasons snaking may not be good for your drains.
It May Push the Blockage Further Into the Drain
A common risk with drain augers, especially if you don't know how to use one correctly, is that it can push the offending debris deep into the drain instead of clearing it. This is particularly likely if the offending debris is a hard object that cannot break easily and cannot be easily snagged by the auger. In such a case, using a drain can actually worsen the problem because deeply-seated clogs are difficult to deal with.
It May Damage Porcelain Surface
Although there are different types of plumbing augers, most of them come with a hard tip for breaking up drain clogs. However, the hard tip may also scratch your porcelain fixture, scarring it and creating an eyesore. If you don't think scratches on your previously gleaming porcelain is bad enough, then you should also know that such damages also accelerate the wear and tear (and hence natural life) of porcelain fixtures.
It May Damage Drain Fixtures
An auger can cause actual physical damage, and not just cosmetic damages, on your plumbing fixtures. This is especially true if you are using a powerful auger, you don't know how to use it properly, and your plumbing pipes are made from vulnerable materials. For example, using a powered auger meant for outdoor drains on your old galvanized pipes can easily crack or even break the pipes.
It Increases the Risk of Rust
Lastly, even if an auger doesn't crack or damage your drain pipes, it may accelerate their demise. This is especially true with galvanized pipes that, ordinarily, do not rust (due to the galvanization). This is because using an auger on such drain pipes damages their protective surface, the surface that ordinarily prevents the pipes from rusting. As a result, corrosion soon sets in and weakens the pipes, necessitating a sooner-than-necessary replacement.
Hopefully, your drains won't clog anytime soon. If you are already dealing with a clogged drain, be gentle with snaking if you have decided to go don that route. Consult your preferred sewer services if snaking doesn't help or if you just need a professional's touch.
