Common Plumbing Mistakes & How to Avoid Them

Common Plumbing Mistakes & How to Avoid Them

February 12, 2025

Plumbing is one of the most vital home maintenance process that tends to go unnoticed until something breaks down. Plumbing errors can result in expensive repairs and a lot of inconvenience. Familiarity about common mistakes that come with plumbing pipe installations and maintenance can be a lifesaver for homeowners in terms of saving time and money. Below is an explanation of common plumbing mistakes and advice on how to avoid them. 
 
1. Selecting the Wrong Pipe Type 

One of the most important plumbing decisions is choosing the proper type of plumbing pipe. Installing the incorrect type of pipe, like a plumber PVC pipe when a metal pipe would be needed, will result in inefficiencies and hazards. For instance, PVC pipes are ideal for drain lines and cold water supply because they resist corrosion and are inexpensive. But they are not ideal for hot water lines since PVC melts when exposed to high temperatures. Always seek advice from a professional to make sure that the proper type of pipe is installed in the proper application. 
 
2. Disregard of Local Codes and Regulations 

Each area has its own set of codes and regulations for plumbing installations. The codes are made to provide safety and efficiency in plumbing systems. Disregarding these codes may lead to inspection failures, penalties, or redoing the plumbing installation. It's important to know the local plumbing codes and, if unsure, just consult a licensed plumber to do the installation. 
 
3. Improper Pipe Sizing 

Employing pipes that are undersized may cause water pressure and slow drainage, while oversized pipes might cause water and energy wastage. Proper pipe sizing is important to allow efficient flow of water and system pressure. It means knowing your home's water usage demands and seeing to it that the diameter of the plumber PVC pipe or any other pipe employed is in accordance with these demands. 
 
4. Over-tightening Connections

 This may sound like a good practice to avoid leaks, but it may actually damage the pipes, particularly if they are PVC or other plastic pipes. Over-tightening may result in cracked fittings or broken seals, which can cause leaks that need to be repaired again. 
 
5. Failing to Support Pipes 

Plumbing pipes must be supported at regular intervals to avoid sagging and breakage over time. Unsupported pipes may bend or sag under the load of water they transport, especially at extreme temperatures. Make sure your plumbing installations have proper support, employing straps at prescribed intervals. 
 
6. Making Complex Repairs on Your Own Without Experience 

While most home repairs can be done as a DIY project, professional hands should be employed for complex plumbing problems. Modifying main supply lines, major work with water heaters, and re-routing sewer pipes are complicated and need an extensive understanding of plumbing systems. Doing these without the necessary skills can result in more disastrous problems, including catastrophic water damage. 
 
Conclusion

Steering clear of the most common plumbing errors starts with knowing the fundamentals of how your home's plumbing system functions and knowing when a task is out of your hands as someone who likes to do things by themselves. Placing the proper type and diameter of plumbing pipe, following local regulations, and calling in professionals when the time comes are all important steps in having an effective and problem-free plumbing system.
