Replacing pipes in your home might seem like a job for the pros, but it’s not always as complicated as it sounds. If you’re dealing with a broken or leaky pipe, you might wonder if it’s something you can handle or if hiring a professional plumber is the smarter option. The truth is, many homeowners can tackle plumbing repairs on their own, but it depends on the situation and your willingness to learn.
How complex is the job?
Replacing a pipe isn’t always as simple as swapping out a piece of plumbing.
The first thing to figure out is the complexity of the plumbing project and underlying issue. For example, replacing a visible section of pipe under the sink is often straightforward. If you’re dealing with plumbing pipes behind walls, under floors, or near your main water line, it’s a different story. These jobs often require experienced plumbers with specialized tools, permits, and a good understanding of plumbing codes and your home’s plumbing layout.
If it’s a minor repair or a pipe you can easily access, DIY might be an option. For more complicated projects, like replacing corroded pipes in hard-to-reach areas, calling a licensed plumber could save you headaches—and avoid potential water damage and more costly repairs.
Some common plumbing issues for DIY-friendly pipe repairs include:
- Replacing a leaky P-trap under the sink.
- Fixing a section of cracked PVC pipe.
- Swapping out a faucet supply line.
- Toilet repair
Some non-DIY plumbing projects that you may want a licensed professional for:
- Installation of tankless water heater
- Replacement of hot water heater
- Sewer line issues
- Water softener installation
If you’re not sure what kind of repair you’re looking at, do some research or watch a few videos online to gauge whether it’s within your comfort zone.
What’s the risk of doing it yourself?
A DIY project gone wrong can sometimes lead to bigger problems.
One of the biggest risks of replacing pipes yourself is not getting the connections right. A poorly sealed pipe can lead to leaks, which might not show up immediately. Over time, water damage can wreak havoc on floors, walls, or cabinets, leaving you with an expensive mess.
Another consideration is water pressure. If pipes aren’t installed correctly, it can affect water flow throughout your home. And if you accidentally damage a major line, you could be looking at severe water damage and an emergency repair bill.
That said, if you’re replacing a simple section of pipe and follow the right steps, the risk is fairly low. Just be sure to:
- Turn off the water supply and drain lines before starting.
- Double-check all connections before turning the water back on.
- Test for leaks by running water through the system.
For anything beyond basic plumbing jobs, it’s okay to recognize your limits and call in a plumbing expert. A licensed plumber will have the experience to handle tough jobs and can give you peace of mind that it’s done right.
Do you have the right tools?
Having the right tools can make or break your DIY plumbing repairs.
Pipe replacement usually involves cutting, fitting, and sealing. For simple projects, you’ll need basic plumbing tools like a pipe cutter, wrench, Teflon tape, and replacement pipes or fittings. Materials will vary based on your home’s plumbing system—older homes might have copper piping, while newer ones often use modern materials like PEX or PVC.
PEX, in particular, is a game changer for DIYers. It’s flexible, easy to cut, and connects using simple crimping tools or expansion fittings depending on the type of piping . Copper pipes, on the other hand, require soldering—a skill that can take time to master, especially when you can't get the water completely out of your plumbing lines, trust me.
When deciding whether to DIY, ask yourself these questions:
- Do I know where my shutoff valve is?
- Do I have the proper tools needed for this job?
- Am I comfortable using basic tools?
- Do I know what type of piping I’m working with?
If you need to buy several expensive tools or you’re unsure about handling certain piping materials, hiring a professional plumbing service might actually cost less in the long run.
FAQ
What is the easiest type of pipe replacement to do yourself?
Swapping out a P-trap under the sink drain is probably one of the easiest DIY plumbing projects, at least in my experience. It only requires basic plumbing tools and a new drain trap, which you can find at most hardware stores. This repair doesn’t involve soldering, making it beginner-friendly. Not to scare you, but make sure to get the connections right. If it's not a fit, it can be a costly mistake involving the dumping of gallons of water through the floor under your sink. 🫣
How much does it cost to hire plumbing services for pipe replacement?
The average cost varies depending on the job and plumbing materials needed. For a simple repair, like replacing a section of visible pipe, you might pay $150–$300. For more complex work, like replacing pipes behind walls or under floors, the bill could range from $1,000 to $5,000 or more. It’s always a good idea to get quotes and labor costs from multiple plumbing professionals to compare pricing. You will most likely pay a premium for emergency plumbing services, but not always.
