Most Common Do It Yourself Mistakes

  1. Dry Cleaner Overuse

When dealing with a major clog, chances are very low you are going to unclog it with a chemical drain cleaner.

These products are effective with minor clogs, but you shouldn’t overuse them.

Any chemical causes a strong reaction in your pipes while spilling it all the time down the drain can only cause significant pipe damage instead of restoring the flow.

Once you exceed the rational use of chemical drain cleaner, it will start building up somewhere down below.

This will abrade the pipes bit by bit, but, what is even more important – can represent a threat to anyone who comes in contact with the chemicals.


If, for any reason, built-up chemicals cause fumes in the pipes, that can cause breathing hazards.

In case you are dealing with a major drain or you have already used a chemical drain cleaner recently, it would be much better to go for a baking soda, hot water, vinegar, and salt.

Even if this doesn’t work, you can try with an auger or a drain snake.

  1. Overtightening


Pipes, fittings, toilet bolts, and supply tubes are very prone to cracking if you overtighten them.

Most of the times, you won’t notice the crank right away, but it will spread millimeter by millimeter, and cause a flood in a couple of weeks.

Don’t take things too rough, no matter if you are working with carbon or PVC pipes, as this can cost you a lot in the future.

  1. Not Slanting the Shower Floor

If you, for any reason, wanted to replace the shower floor in your bathroom, remember that plumbing works according to the principle of gravity.

One of the most common mistakes with do it yourself plumbing is not providing water to flow downward.

People usually forget water flows only at a precise angle, and they create a perfect spot for molds and bacteria, intentionally.

Take a slope while installing a shower floor. Ideally, you should slope it at a four percent angle.

  1. Gluing

As we mentioned in the previous chapter, you want to be well informed when doing anything about plumbing.

Remember that, when you want to seal something in your plumbing system, you don’t need glue, but a plumber’s putty.

You wouldn’t believe how many people make this mistake.

  1. Forgetting about Measurements



Plumbing requires concentration and precision. If you made a cut on a pipe, you want to get a new piece that will fit into, right?

Another common mistake is not writing down measurements of the replacement part.


  1. Sweat Those Pipes

If you are a complete beginner with do it yourself plumbing, this trick is something you should remember for life.

Once you learn how to sweat copper pipes, you passed the test.

First of all – you will like it because it is so easy. Secondly, you will learn how to fix smaller pipe issues in a very functional way.

Listen, you won’t make it look flawless, but you will get things done.

If you are a real perfectionist, then you should better pay to an expert to fix the pipes.

However, you can’t be completely confident about anyone actually.

To perform this task, you would have to visit a local hardware shop and purchase a couple of items:
A small torch (if you don’t have one already),
Pieces of copper pipe.

Now you have everything you need, and you are ready to unlock the carbon pipe mystery.
Clean the pipes you want to fix and clean the copper pieces you bought.

Next, heat the joint and take a little bit of flux. Once you do so, apply the solder. Ta-da!

You see it is so simple, yet it will save your pockets for a long time.

If you are trying this for the first time, you would probably be a bit clumsy, but don’t worry – you will still fix the pipe.

After all, the most important thing is that your joints would be nice and renovated.

  1. Showerhead Issues

If you are dealing with a dripping showerhead, there is a great chance you can fix it within a couple of minutes.

In most of the cases, dripping is a sign of improperly connected threads.

Take the showerhead off, wrap tape in a clockwise direction, and take the head back.

On the other hand, if you noticed reduced water pressure coming out of your showerhead, that means only one thing – it is clogged.

You will fix it easily if you take it off and soak in warm water and vinegar.

Vinegar will abrade mineral deposits blocking the normal water spray.

  1. Lose Pipe Fittings 

A pipe wrench is not the answer in most of the cases.

When it comes to plumbing, use your mind rather than your strength.

Applying brute force won’t lose hardened fittings.

However, heat would, totally.

Use a propane torch and apply the heat for a couple of minutes.

Make sure there are no gas or plastic pipes in the area and cover your hands with a heat-resistant cloth.

After you finish your work, make sure that you put isolation on your pipes to prevent freezing.


You can handle at least 60% of plumbing repairs by yourself.

There is no need for calling a professional for a small leak or a clog.

Plumbers charge from $45 to $200 per hour, and you can save a lot of money if you follow the instructions and learn on other people’s mistakes.

Yet, we still advise you to have an expert number in your wallet in case things go down.
Hopefully, you will perform any of do it yourself plumbing project successfully.

Good luck!
