What Causes Clogged Drains?
Different things can clog different types of drains in your St. Louis home, but most blockages come from the same handful of common culprits. Here are the main causes:
Hair is a common culprit in showers, tubs, and bathroom sinks. Even tiny strands of hair that build up can tangle with soap scum and form a rope-like clog that slows drainage over time.
Even with a garbage disposal, food waste like eggshells, coffee grounds, vegetables, rice, and other food scraps don't break down easily and can pile up.
Kitchen sinks are also often clogged by grease and fat that harden inside the drain and stick to pipes, trapping food scraps.
Soap scum is a residue left over when soap mixes with minerals in water, which hardens, traps dirt, dead skin, and bacteria, and clings to the insides of pipes. Toothpaste scum in bathroom sinks can trap other objects like hair.
Mineral buildup (hard water) is common in all drains. The hard water minerals (mostly calcium and magnesium) slowly deposits on the inside of your pipes, narrowing the opening.
Toilets are often clogged by items such as feminine products, wipes (even "flushable" ones), paper towels, and cotton swabs, that don't break down and get stuck in the pipe. If it's not toiler paper, don't flush it.
Tree roots grow towards water, breaking main sewer lines and slowing down every drain in your St. Louis home.
Broken or collapsed pipes, especially common in older homes, allow foreign particles and dirt to enter the drainage system, disrupting water flow. Undersized pipes can't handle buildup as easily as larger pipes.
Basement drains and laundry drains can be clogged by debris and sediment like dirt, leaves, and lint that collect in the trap and form a solid clog.
Why Do My Drains Keep Getting Clogged?
Even if you successfully unclog a drain once, it can keep backing up and you can suffer recurring blockages. There are a few reason why:
- A clog has made it's way further down the line, and DIY fixes like plungers or store-bought cleaners can't reach it.
- The clogs are happening because of major issues, like broken pipes or tree roots, so drains keep blocking no matter how many surface-level clogs you remove.
- If multiple drains, like a kitchen sink, bathroom drain, or laundry line all lead to the same clogged section of a pipe, fixing one won't help the others.
- There's a sag or low spot in the pipe (called "Bellies") that collects debris, and the trapped material keeps forming new clogs.
- Everyday habits, like rinsing grease down the kitchen sink, letting hair go down the shower drain, or flushing wipes, keep rebuilding the same type of clog even after you clear it.
How to Unclog a Drain Yourself
Before calling a plumber, it's worth trying a few DIY drain cleaning methods to see if you can resolve the problem yourself:
- Try Hot Water First: Boil a kettle or pot-full of water down the drain in question. This can loosen grease, soap residue, and small buildups in sinks and tubs.
- Remove the Stopper or Drain Cover: Try to reach visible hair, food, or debris with your hand or a bent wire hanger hook.
- Try Dish Soap: For kitchen sinks with greasy buildup, pour a generous amount of dishwashing liquid into the drain and let it sit about 10 minutes to dissolve grease.
- Make Your Own Drain Cleaner: Mixing one cup white vinegar and one cup baking soda carbon dioxide bubbles. The bubbling and fizzing helps loosen light buildup. Pouring hot water down the drain afterwards helps flush the debris.
- Use a Plunger: A few solid plunges can clear surface-level blockages in toilets, bathroom sinks, and kitchen drains. Cover the overflow opening so you get full pressure with each plunge.
- Use a Drain Snake / Augur: By feeding the coil gently into the drain, you can pull out hair, food, and other debris.
When to Call a Professional St. Louis Plumber for a Clogged Drain
If DIY methods don't work and the drainage issues keep recurring in your St. Louis home, you'll probably need to call a plumber in St. Louis to fix unclog the drain professionally. Here are some signs it's time to call:
- DIY Methods Don't Work: If you've tried hot water, vinegar and baking soda, a plunger or augur, or any other DIY trick but are still having issues, the clog is likely above your pay grade.
- The Clog Keeps Coming Back: If you clear a drain and it slows down again a few days or weeks later, that usually means there's a deeper issue in the line that DIY tools can’t reach.
- Multiple Drains Are Backed Up at Once: If multiple drains are clogged, especially in different rooms (for example, kitchen, bathroom, and laundry), the problem is usually in the main sewer line.
- Water is Backing Up Into Other Drain: If running one fixture causes water to bubble up in another drain, for example, if water comes up in the tub while you're running the sink, it's a clear sign the main line is blocked and the clog is beyond your reach.
- Complete Blockage: If no water is draining at all, don't try and force water through. It usually means the pipe is fully blocked and needs professional equipment to clear.
- You Can’t Access the Clog Safely: Floor drains, basement drains, old pipes, or hard-to-reach cleanouts often need specialized tools to clear without causing damage.
