February 20, 2025Ever found yourself staring at a shelf full of copper pipes at the hardware store, wondering which one to pick?
If you’re tackling DIY plumbing projects, knowing the right type of copper pipe can save you time, money, and headaches.
In this guide, we’ll break down Type L vs. Type M copper pipes, covering their durability, cost, and best uses so you can make an informed decision.
And if DIY plumbing isn’t your thing, at least you’ll know what to ask for when calling a professional plumbers.
Let’s get started!
Different Types of Copper Pipe
Now, let’s get into the details. The two most common types of copper pipes you’ll come across are Type L and Type M.
At first glance, they might look nearly identical, but choosing the wrong one could make a big difference in your plumbing project.
So, which one is right for you? Let’s break it down.
1. Type L Copper Pipe
Type L is the tougher option. It has thicker walls, which makes it more durable and resistant to pressure. That’s why it’s often used for water supply lines, both inside and outside homes.
If you’re working on something that needs to last—like underground water lines or high-pressure systems—Type L is your best bet.
2. Type M Copper Pipe
Type M is the lightweight option. It has thinner walls compared to Type L, so it’s more affordable and easier to work with.
Many homeowners and DIYers love it for standard home plumbing. If you’re replacing water pipes in a single-family home or installing new lines for a renovation, Type M is usually good enough.
Differences Between Type L and Type M Copper Pipe
Now, let’s dive into the details. By the end of this, you won’t have to wonder about the difference between Type L and Type M copper pipes ever again!
1. Cost
If you’re on a budget, Type M is the more affordable option. Since it has thinner walls, meaning less copper is used in manufacturing, which keeps costs down.
Type L, on the other hand, is thicker and more durable, but that extra material makes it more expensive.
If cost is a major factor and you’re working on a standard residential project, Type M might be the way to go.
However, for long-term reliability, many plumbers still prefer Type L despite the higher price tag.
2. Durability
When it comes to longevity, Type L wins. Its thicker walls make it more resistant to corrosion and external damage, which is why it’s often used in underground and high-pressure applications.
Type M, while still reliable, is better suited for low-pressure systems inside homes where heavy wear and tear aren’t a concern.
If your pipes will be exposed to harsh conditions, Type L is worth the investment.
3. Water Pressure Handling
Since Type L has thicker walls, it can handle higher water pressure, it is ideal for commercial buildings or homes with powerful plumbing systems.
Type M is fine for standard water pressure but might not hold up in areas with high demands.
4. Application
Think about where you’re installing the pipes. Type M works well for residential water supply lines that don’t require extreme durability.
Type L is commonly used for commercial settings, underground installations, and places where plumbing fixtures need extra reinforcement.
Some building codes even require Type L for certain applications, so be sure to check local regulations before making a decision.
5. Versatility
Type L is more versatile since it can be used in both residential and commercial settings. It’s often the go-to choice for professional plumbers because of its adaptability.
Type M, on the other hand, has more limited application that makes it less versatile
