Tips on handling clogged drains
Realizing that your drain may be clogged is one of the worst nightmares of any homeowner.
The first sign that you may be dealing with a clogging problem is when the water starts taking more time to drain after using the sink, shower, bathtub, or toilet.
But instead of panicking, you should know that there are ways to handle a slowed down drain before matters get serious and messy.
The first thing you should try is using a plunger. This simple and yet indispensable tool can help create a vacuum that may be able to suction out the hair, soap scum, or other matter which is causing your drain to malfunction.
Another tip is to try releasing the build-up of organic matter from the drain by pouring some hot water directly into it. Try using near-boiling water, and pour it carefully and slowly down the clogged drain. This simple hack may be able to clear out part of the build-up.
One highly efficient home remedy for unclogging drains is to use vinegar and baking soda.
Mix a cup of vinegar with baking soda in a bowl in an equal ratio. Stir it, and then pour the fizzing mixture slowly into the problematic drain. You will be able to see the chemical reaction which occurs, as bubbles and fizzing will most likely happen as the mixture “attacks” the organic matter build-up.
Let the mixture do its magic for about an hour, and then flush the drain with hot water. Hopefully, this simple hack will resolve your problem.
Another way to tackle the build-up of gunk in your drains is to use a wire hanger.
First, you will need to straighten it and then form a hook on one of its ends. Then poke the hook into the drain until you feel the clog, and start pulling out the hair and other gunk that has gotten stuck inside.
This is a messier procedure, but you will be amazed at the results. After you make sure that you have gotten all of the gunk out and have disposed of it, flush the drain with near-boiling water to flush out all of the smaller particles.
Instead of a wire hanger, you can use a plumber’s snake, which is a wire that you can use to dislodge any build-ups and push away or remove the clogs.
If none of these home remedies seem to work, you should opt for an efficient and yet safe drain cleaner – one which will help you unblock the drains but without causing potential harm to your pipes and fixtures.
If you are striving to live a more eco-friendly life, you should choose a biodegradable and environmentally friendly drain cleaner.
The last resort is calling a professional plumber to take care of your clogged drain.
In any case, the earlier you handle a problem with your drains, the fewer potentially serious and costly consequences there will be.
This is why experts recommend that you use a reliable drain cleaner on a regular basis as a preventive maintenance measure so that you don’t have to deal with messy and unpleasant clogs.
Pros and cons of using commercial drain cleaners
If you are still deliberating on whether you should use a commercially available drain cleaner to resolve slow draining or a complete block, then here are some of the main pros and cons which may help you decide:
- The commercially available drain cleaners come with detailed instructions about how to use them safely and are generally safe to use by DIYers
- Drain cleaners rely on some sort of chemical reaction to resolve clogs, so there is no risk of mechanically damaging your pipes with them
- You don’t need special tools or have professional skills to use a drain cleaner from the store
- The drain cleaners are ready to use, without the need of being mixed or otherwise prepared, so all you will need to do is pour them in the problematic drain straight from the container
- Many of the good quality drain cleaners do not emit a smell, so you can use them at home or anywhere else without fear of bad odors
- Most of the drain cleaners can resolve the problem in a matter of a few minutes, so they are a quick solution
- Drain cleaners are an excellent solution if your drain has been clogged by hair, grease, soap scum, or food
- Buying a drain cleaner is much less expensive than hiring a professional plumber to tackle the problem
- A majority of the drain cleaners from our list can be used for preventive maintenance so that you don’t end up with slow draining or clogging problems
- You should be careful about the content of the drain cleaner because it may contain pollutants that can get into the groundwater, soil and pollute the environment and drinking water
- Drain cleaners are universal, and usually, work by dissolving organic matter, so they may not be efficient if you have a non-organic object or a mineral build-up blocking your pipes
- In some cases, the drain cleaner may simply resolve the clogging but without preventing further build-up in the pipes and clogging
- Some chemical-based drain cleaners can be dangerous if not handled properly and may cause burns and emit toxic fumes
- Using the wrong drain cleaner can actually damage your pipes, by softening PVC pipes or corroding metal ones
- Some chemical drain cleaners may cause damage to septic tanks or garbage disposals
- Very few drain cleaners are capable of resolving complete blocks
Simple ways to prevent clogs
If you want to ensure that your pipes and plumbing system functions well and that you don’t end up faced with a messy drain clog, some simple solutions can help you minimize the risk of clogging.
Here are some tips which will save you the time, hassle, and money for dealing with clogged drains:
- Use natural enzyme and bacterial drain cleaners or biodegradable solutions as preventive care and maintenance. These drain cleaners do not cause corrosion, and in most cases will not kill off the bacteria in your septic system
- Place strainers on top of your drains. Strainers are inexpensive items that can help collect the larger particles like food, hair, and others and prevent them from ending up in your drain and pipes
- Remove the hair and other gunk from the drain in the sink, shower or bathtub with a wire, or with needle-nosed pliers. Even though this is not a particularly pleasant task, it will help prevent serious clogging in the future
- If the mainline of your sewer tends to get clogged every year or quite often, the problem could be caused by roots, collapsed pipes, clay tile joints, and others, so it makes sense to ask a plumber to visually inspect the mainline with a scope and identify and resolve this problem once and for all
- Use a lint catcher for the washing machine drain. This will help capture and trap the lint which can come from the fabrics you wash, as well as particles from leftover tissues or others that make their way into your laundry. The simple solution is to install a lint catcher or even a nylon stocking at the end of the drain hose, and then make sure that you check it and replace it on a regular basis if it is full
- Don’t dump the grease from cooking down the drain. Warm fat will easily get attached to the pipes, and build up over time, eventually causing a clock in your kitchen sink. So instead of draining the leftover grease after frying or cooking something, collect it in a can or other container to reuse it, or to dispose of it in a safe manner by taking it to a recycling center
- Don’t dump the coffee from the filter or portafilter of your coffee maker into the drain
- Throw away as much of the leftover food from your plates and pots into the trash instead of the garbage disposal
- Place a washcloth over the shower drain before bathing your dog
- Never rinse of buckets and tools with cement, sand, joint compound, or grout down the drains. If these materials from your home construction project harden up in your drains, you can end up with very hard to remove rock-hard clogs
- Use a pop-up stopper and clean it once a week. Pop up stoppers which are used for drains in sinks can efficiently trap a lot of the hairs, soap scum, toothpaste, and grease from cosmetics which will otherwise end up in your pipes
- Abstain from flushing anything different than human waste and toilet paper in your toilet
- Throw feminine hygiene products, baby wipes, dental floss, Q-tips and other similar items in the trash rather than attempting to flush them down the toilet
The best types of drain cleaners for different clog types
Keep in mind that the different types of clogs require different approaches if you want the best results.
The chemical drain cleaners on the market are usually basic or acidic. Each type is efficient for handling different types of clogs caused by different types of organic matter.
For showers and baths or bathroom sinks, where the clogs are usually caused by hair, soap scum, gunk, and oils from cosmetics, so an acidic solution or one which attacks this type of matter should be used.
As for kitchens, where the drain is usually clogged by grease and parts of food, using an alkaline-based drain cleaning solution is a better approach.
