Here are the Top 7 Costly Mistakes Most Plumbing DIYers Make

If you’re a DIYer, then you know that plumbing can be a tricky business. There are a lot of things that can go wrong, and it’s often hard to know where to start. That’s why we’ve put together this comprehensive guide to the seven most common plumbing mistakes DIYers make.

We’ll cover everything from common errors when installing fixtures to mistakes made when trying to clear a clogged drain. By the end of this guide, you’ll know exactly what to watch out for next time you’re tackling a plumbing project. So let’s get started!

1. Not Knowing Your Water Pressure

One of the most common mistakes DIYers make is not knowing their water pressure. This can lead to a number of problems, such as fixtures not working properly or even bursting pipes.

To avoid these issues, it’s important to always know what your water pressure is before starting any plumbing project. You can typically find this information on your water bill or by contacting your local water utility.

2. Not Using the Right Pipes

Another common mistake is using the wrong type of pipe for your project. There are a variety of different types of pipes available on the market, and each has its own unique benefits and drawbacks.

For example, PVC pipes are a popular choice for many DIY plumbing projects because they’re inexpensive and easy to work with. However, they’re not always the best choice for every application.

If you’re not sure which type of pipe is right for your project, it’s always best to consult with a professional before making your purchase.

3. Not Using Enough Pipe Insulation

Insulating your pipes is an important part of any plumbing project, but it’s often overlooked by DIYers. This can lead to several problems, such as frozen pipes or excessive noise from your plumbing.

To avoid these issues, be sure to use the proper type and amount of pipe insulation for your project. This will help to keep your pipes protected from the elements and will also reduce noise.

4. Not Properly Sealing Joints

If you’re not careful, it’s easy to make mistakes when sealing joints in your plumbing. This can lead to leaks, which can cause extensive damage to your home.

To avoid these issues, be sure to use the proper type of sealant for your project and to follow the manufacturer’s instructions carefully. This will help to ensure that your joints are properly sealed and will prevent leaks.

5. Not Venting Properly

Venting is important to the proper functioning of your plumbing system. Without proper venting, your drains will not work properly and could cause serious damage to your home.

Be sure to follow the manufacturer’s instructions carefully when installing vents in your plumbing system. This will help to ensure that your system is properly vented and will prevent any damage to your home.

6. Using Drain Cleaners as a First Choice

Drain cleaners can be very helpful in clearing clogged drains, but they should not be used as a first choice. Drain cleaners are very harsh chemicals that can damage your pipes and cause more problems than they solve.

If you must use a drain cleaner, be sure to follow the manufacturer’s instructions carefully and to use the cleaner in moderation. This will help to prevent any damage to your pipes and will keep your drains flowing freely.

7. Using Too Much Muscle On a Stuck Shut-Off Valve

If you’re having trouble turning a shut-off valve, it’s important to use the proper amount of force. Using too much force can damage the valve and make it more difficult to turn in the future.

If you’re having trouble turning a shut-off valve, try using a wrench or another tool to help you. This will help to prevent any damage to the valve and will make it easier to turn in the future.


There are a few plumbing mistakes that are commonly made by DIYers. These include not properly shutting off the water before starting work, not using the proper tools and techniques, and not being familiar with the local building codes. While these mistakes can be easily avoided, they can still lead to costly repairs or even damage to your home. If you are unsure about anything, it is always best to consult a professional before proceeding.
