5 Mistakes to Avoid When Installing Plumbing

It is common for homeowners to deal with plumbing works that keep giving trouble after a new installation. The pipes may leak or a newly installed tap may not work. Making mistakes during plumbing installation is simply the most common reason behind such problems.

Many plumbing installation jobs are DIY projects. If you know the most common mistakes involved in such installation work, you can avoid them to increase the success rate of the jobs.

Here are 5 mistakes to avoid when installing plumbing.

1. Lack of Permits

Before you carry out any plumbing installation, it is important to check whether the job needs a permit or not. It is a common mistake to completely ignore this requirement. You may not only have to pay fines, but it can also delay the plumbing work. This makes increases the cost of a plumbing job.

2. Using Incorrect Pipes or Materials

There are different types of pipes and they are meant for different applications. It is a common mistake to use the wrong pipes due to a lack of knowledge. Consider the following example:

  • Gray water lines are meant to be used for carrying wastewater from washing machines, sinks, and bathtubs.
  • Black water lines are meant for sewage flow.

Another common mistake is connecting copper and galvanized pipes. This can increase the risk of corrosion, further causing problems such as leaks and clogs. A dielectric fitting must go between both of these pipe materials. Such material mismatches are likely to happen when working on plumbing systems in older houses. It is often difficult to find the same materials that were used decades ago.

Another related mistake is to use PVC pipes in places where metal pipes are required. This is another common mistake among beginners, as PVC pipes are easier to cut and work with. For applications involving the use of hot water, it is recommended to use metal pipes and not plastic pipes. Using the wrong-sized pipes is also a common mistake.

3. Lack of Essential Tools

It is a common mistake among DIYers to not gather all the essential tools and materials before beginning a plumbing installation job. If you do a little research to ensure you have all the right tools, it can save both inconvenience and valuable time.

This is one factor that differentiates a professional from an amateur. Having the proper tools and materials makes the job easier and speedier. Besides, the incorrect tools can also cause damage to the pipes or other plumbing systems or lead to incorrect installation.

4. Not Shutting Off Water

It is common among DIYers to forget to turn-off the water before beginning a plumbing installation job. This mistake can cause flooding and water damage. There are different points where you can turn off your water supply. Such points include:

  • Under the fixture
  • Close to the water meter
  • Beside the water heater

If a fixture requires electricity for installation, you should be able to handle electrical wiring properly and safely. If you are unsure about it, it is recommended to hire the services of a licensed professional.

5. Handling Plumbing Jobs Beyond Your Skills

Not every plumbing installation project is meant to be a DIY work. Many times, the plumbing jobs are outside the scope of your skills and knowledge. Such jobs should be handled only by qualified and experienced plumbers.

There are many advantages of getting professional help instead of handling plumbing jobs yourselves:

  • There are lesser chances that a plumber can make a mistake leading to leaks or property damage
  • Plumbers have insurance and license and if there are any problems, the damage is usually covered

When it comes to complex plumbing installations, it is best to seek professional help.

So, these are some of the most common mistakes to avoid during plumbing installation. If you are unsure about a job, it is best to get professional help instead of taking any risks.
