Common Causes of Blocked Drains

A clogged drain can cause a significant amount of stress and trouble within a household.  The sight of murky water, awful smell if left to stay, and the slimy feel is sickening. So you want to get rid of the blocked drain as soon as you can. 

Clogged pipes should not bother you as much since they are quite common in indoor plumbing. Besides, unclogging a blocked drain is not a hard task if you have the right tools. However,  you can’t solve the issue if you don’t know the cause. In most situations, you have to find the problem for you to fix it. That's why it would be a good idea to read on and discover some of the major causes of clogged drains, so you can get rid of the issue permanently if possible:

1. Hair

Hair is one of the most common causes for blockages, especially in bathrooms. It is often combined with sticky substances such as grease to form a nasty clog. Therefore, if you want to get rid of such clogs, you have to prevent hair from getting into the drain.  To solve this issue, you need to install a drain guard that can catch hair which has fallen off. You can, then, get rid of any hair you find on the guard to keep the area debris free, and you’ll have fewer blockages.

2. Toilet Paper Build-up

Too much toilet paper could easily clog your toilet, reducing water flow through its draining pipe. That is an easy problem to solve, since it only requires a plunger, if water is still flowing, but at a slower rate. If there is no flow, however, consider calling a professional for assistance.

3. Food Waste

You might think that it’s okay to let food waste go down the drain because you have a food waste disposal in your sink, but that is not always right. A better plan would be to get a composting pile, which would be quite effective as well in getting rid of any leftovers from your family meals. Be cautious of oils and try not to let them get into the drain since they will solidify and cause a blockage.

4. Tree Roots

If tree or plant roots find their way into underground pipes by any means, a lot of damage could result, and such situations will easily obstruct the flow of any liquid flowing through the affected pipes. To avoid that, you have to review the structure of plants that near underground drain pipes, and always monitor such a plumbing system to prevent costly damages.

5. Soap

Are you wondering how soap could clog your pipe? It’s not as complicated as you think, as traditional soap bars are made with a greasy substance that when combined with minerals in water forms soap scum, a hard residue that will easily block drains. You might want to switch to soap-free washing, as well as pressure-cleaning your pipes once in a while, to get rid of the residue, if any.

6. Mineral Build-up

Hard water has minerals dissolved in it, and these minerals can easily build up, leaving insoluble substances that get attached to pipes, eventually blocking them. To get rid of such kinds of blockages, you might want to get a water softener if you have hard water in your home. If you don’t want to get that, then consider removing any buildup from your drain regularly, to avoid an established clog which is always hard to remove. If your pipes and drains get blocked from such clogs, the best solution would be to call a professional plumber.

7. Dirt

So now you want to take advantage of the pipes and drains in your home by letting them wash away anything that can pass through them? While that is a common mistake, ensure that you shake or wash off the excess dirt on whatever you want to clean while outside, before getting inside for a thorough cleaning.

8. Small Objects

Sometimes small objects might find their way into the water supply and end up getting into the drain. Always ensure that only the substances that should go into drainpipes get into them since repairs from clogged pipes can get tedious and even expensive at times.
