How Do Drains Get Clogged?

Plumbers unclog drains on a regular basis, but how do drains get clogged in the first place? You might encounter this problem in your home and need to understand ways to fix the clog and prevent it from being a recurring problem. Grasshopper Heating, Cooling, Plumbing & Electrical reveals everything you need to know in this helpful guide.

How a Clogged Drain Affects Your Plumbing System

Say you have a clogged sink drain and don’t do anything to fix it. The blockage will continue to grow and restrict water flow through your system. In addition, foul odors can waft from your drain because of the clog.

Be mindful of how you approach clogged drains. Some at-home remedies can fix the problem but commercial cleaning products that feature harsh chemicals can damage your pipes. Consult a professional plumber if you have concerns and let them inspect your drainage system.

Common Causes of Clogged Drains

How do drains get clogged? Multiple items can be to blame for clogging the drain pipe in your bathroom sink, toilet bowl, shower, and kitchen sink. Check out some of the biggest culprits below.

Toilet Paper, Paper Towels, and Feminine Hygiene Products

If human waste doesn’t lead to a clogged toilet, certain toiletries may be responsible. Flushing thick wads of paper towels and feminine products can block the pipe and cause water backup. Flush only toilet paper and use a reasonable amount, as this could also clog the toilet.

Mineral Deposits

Many bathroom drain clogs form because of excessive mineral buildup within the pipes. You might be tempted to use a chemical cleaner but this can eat away at your pipes. Experts recommend a hydrojetting service that uses pressurized water to blast away all built-up minerals.

Hair and Soap Scum

Shower drains tend to clog with hair and residue from bar soap. Drain screens can protect the plumbing pipes but if residue manages to get through them, you can use the following steps to break down the clog:

  • Fill the drain with a cup of baking soda.
  • Pour a cup of vinegar into the drain to form a chemical reaction.
  • Let the mixture sit for 30 minutes, and flush the pipe with boiling water.
  • Repeat the process if necessary.

Tree Roots

If you have a clogged kitchen sink but use a drain cover and garbage disposal to keep food out of the drain line, a tree may be obstructing the pipe. Roots expand as the tree grows and can infiltrate plumbing systems. Call a professional plumber to inspect the drain pipes and clear the obstruction.

Using hot water or chemical drain cleaners to clear the way won’t do the trick if a tree’s roots are to blame.
