How To Prevent Blocked Drains

Have you got a blocked drain in your kitchen or bathroom? Find out what causes it and how to prevent future blockages.

Dealing with a clogged drain can be an absolute nightmare. Whether it’s the kitchen sink, bathroom basin, or the outdoor sewer drain, blockages can cause chaos on your property. Often, a drain blockage is a sign of a more significant plumbing issue lurking in the pipes.

Blocked Drain Prevention

What’s Blocking My Drains?

Clogged drains can occur for several different reasons. Let’s look at some reasons why you may have clogged drains.

Food

Food waste can get washed down the drain and build up in the pipes. Some food items cannot decompose and become lodged in the pipe walls.

Debris/Foreign Objects

It’s surprisingly easy to lose small items like jewellery down the sink, and kids have a knack for flushing toys down the toilet. When something too large for the pipes ends up there, you can bet it will block the water flow.

Soap/Hair

The shower drain is susceptible to a build-up of hair and soap. Hair is a significant factor in a bathroom or shower drain clogging up. Shampoo can be overly greasy and hard to disintegrate.

Oil

Once cooking oils and food grease cool inside the pipework, they solidify, creating a barrier that obstructs water flow.

Toilet Paper

Using too much toilet paper is bad for your pipes. A blockage can occur if you flush excess paper and other material down the sewer drain.

Tree Roots

Tree roots are strong, and once they start growing inside your pipes, they will cause the pipework to become weak and break. Tree root invasion is a common culprit in clogging your pipeline.

Damaged Drain Pipes

If there is rust in your water channels or you have an older property, the drainpipes are likely weak and at risk of cracking.

How Do I Stop My Drains From Blocking?

Some easy tips are for preventing clogged drains and maintaining your drainage system. All you need to do is adjust your daily routine and be cautious of what you put down your gutters and stormwater drains.

  • Dispose of cooking oil and used grease in a container and place in a garbage bin. Do not wash cooking grease down the sink to prevent blocked drains.
  • Invest in a drain strainer to catch food scraps before they reach the sink opening. These can also be used in shower drains to prevent hair clogs and other drain blockages.
  • Only flush water and human waste down the toilet, and be mindful of how much toilet paper you use to avoid blocked toilets.
  • Proper rubbish disposal is vital, as items washed down the line can harm the sewer system and your household plumbing system.
  • Clearing your drains regularly through a local licensed plumber is the best way to avoid a clog in the line and detect potential issues like a collapsed or crushed drain.
  • To maintain the health of your drainage system, it is best not to throw coffee grounds, paper towels, cat litter, paint, and some household cleaners down the drain.

What Can I Pour Down A Drain To Unclog It?

Many items on the market claim to clear clogs and drain blockages in the drains. Instead of unclogging blocked pipes, these products may do more harm than good. Some chemicals may be too harsh on the plumbing and cause your channels to weaken.

Got a pesky minor clog? Here’s a quick, eco-friendly fix. You probably have everything you need right at home:

  • 1/2 cup of baking soda,
  • 1 cup of vinegar, and
  • Boiling water

Start by slowly pouring the water down the drain, followed by 1/2 baking soda and vinegar. Cover the drain with a plug and let the mixture work for 5-10 minutes. Finish off by trying to pour boiling water again.

Be cautious when pouring hot water, and don’t forget to wear gloves to prevent burns. The fizzing reaction from the soda and vinegar mix will break down small clogs like grease, soap, and hair. A good rinse with household washing solution is also handy for keeping those sink odours in check.

Prevent Blocked Drains

Keeping your drains in good shape is crucial for a smoothly running home. Still, it’s easy for clogs to happen from tossing the wrong things down the sink or just by accident. Plus, some leaks or issues might lurk undetected until they become a bigger problem.

Changing a few habits, getting your hands dirty, and putting more time and attention into your home’s drains may save you a lot of money.

If you notice water pooling in your yard, drains emptying slowly, or hear gurgling sounds from your sinks, these could all be signs of a major blockage.
