Have you ever struggled with removing old PEX piping during a renovation, only to find that cutting it out piece by piece takes hours instead of minutes? It is a common frustration for both professional plumbers and DIY enthusiasts who value efficiency and clean workspaces. Finding the right Moore Plumbing Supply split up machine for Pex Pipe can transform this tedious task into a quick, precise operation, saving you time and physical strain.
In this guide, we will explore everything you need to know about selecting, using, and maintaining pipe splitting tools available through reputable suppliers like Moore Plumbing Supply. Whether you are dealing with tight spaces or large-scale commercial jobs, understanding the mechanics of these machines ensures you get the best return on your investment.
What Is a PEX Pipe Splitting Machine?
Before diving into specific models, it is essential to understand what a “split up” or pipe splitting machine actually does. Unlike traditional cutters that sever the pipe entirely, a splitting machine is designed to slice through the length of the pipe longitudinally. This is particularly useful when you need to remove PEX tubing that is already installed behind walls or under floors without damaging the surrounding structure.
Why Use a Splitter Instead of a Cutter?
Traditional PEX cutters are excellent for trimming pipes to length before installation. However, removal requires a different approach. A splitting tool allows you to:
- Preserve Surrounding Materials: By slicing the pipe open, you can peel it away from studs or joists without tearing drywall.
- Increase Speed: One pass along the pipe’s length is faster than making multiple cross-cuts.
- Reduce Waste: In some recycling scenarios, split pipes are easier to process than tangled masses of cut tubing.
While Moore Plumbing Supply offers a vast array of tools, identifying the specific “split up” mechanism is key. Often, these are manual hand-held tools or specialized attachments for rotary tools, rather than large industrial “machines” for residential use.
Top Features to Look for in a PEX Splitting Tool
When browsing the inventory at Moore Plumbing Supply or similar distributors, not all tools are created equal. Here are the critical features that define a high-quality PEX splitting device.
1. Blade Durability and Material
The blade is the heart of the tool. Look for high-carbon steel or coated blades that resist corrosion. PEX pipe can be tough, and a dull blade will snag, potentially damaging the pipe insulation or the wall cavity.
2. Ergonomic Design
Since you may be working in awkward positions, an ergonomic handle is non-negotiable. A comfortable grip reduces hand fatigue during extended use.
3. Compatibility with Pipe Sizes
Ensure the tool supports standard PEX sizes: 1/2-inch, 3/4-inch, and 1-inch. Some universal splitters adjust to fit multiple diameters, offering better versatility.
4. Safety Guards
A good splitting tool should have a guard that prevents the blade from digging too deep into the substrate behind the pipe. This protects your structural elements from accidental nicks.

How to Use a PEX Pipe Splitting Tool: Step-by-Step
Using a splitting tool correctly ensures safety and efficiency. Follow these steps for optimal results.
Step 1: Prepare the Area Clear any debris around the exposed section of the PEX pipe. Ensure you have enough visibility to see the entire length you intend to split.
Step 2: Secure the Pipe If possible, stabilize the pipe so it does not vibrate or move excessively. In tight spaces, you may need to hold it steady with one hand while operating the tool with the other.
Step 3: Position the Blade Insert the blade of the splitting tool under the edge of the PEX pipe. Align it with the direction you want to split (usually along the longest accessible run).
Step 4: Apply Steady Pressure Push the tool forward along the length of the pipe. Do not force it; let the sharpness of the blade do the work. If you encounter resistance, check for kinks or fittings that may block the path.
Step 5: Peel and Remove Once the pipe is split longitudinally, you can easily peel the two halves away from the mounting clips or staples. Dispose of the material responsibly.
Pro Tip: If the PEX pipe is frozen or brittle due to cold temperatures, allow it to reach room temperature before splitting to prevent shattering.

Common Mistakes to Avoid When Splitting PEX
Even with the best tools, errors can occur. Here are the most frequent pitfalls:
- Ignoring Fittings: Never attempt to split through a brass or plastic fitting. Always stop before reaching a connection point.
- Using Dull Blades: A dull blade requires more force, increasing the risk of slipping and injury. Replace blades regularly.
- Splitting Pressurized Lines: Always ensure the water supply is turned off and the pipe is depressurized before attempting any modification.
For more detailed information on PEX material properties and safety standards, you can refer to the comprehensive overview on Wikipedia. Understanding the chemical composition of Cross-linked Polyethylene helps in choosing the right mechanical approach for handling it.
Maintenance Tips for Your Splitting Tool
To extend the life of your tool, follow these simple maintenance routines:
- Clean After Use: Wipe down the blade and handle to remove plastic residue and dust.
- Lubricate Moving Parts: If your splitter has adjustable components, apply a light machine oil to keep them moving smoothly.
- Store Properly: Keep the tool in a dry place to prevent rust. Use a blade cover if provided.
FAQ Section
1. Can I use a standard utility knife to split PEX pipe?
While a utility knife can technically cut PEX, it is not safe or efficient for longitudinal splitting. Utility knives lack the depth control and stability of a dedicated splitting tool, increasing the risk of injury and damage to surrounding walls.
2. Is a “split up machine” the same as a PEX crimping tool?
No. A crimping tool is used to connect PEX pipes to fittings using metal rings. A splitting tool is used for removal or modification of existing pipes. They serve opposite purposes in the plumbing workflow.
3. Does Moore Plumbing Supply offer warranty on their tools?
Most professional-grade tools sold by Moore Plumbing Supply come with a manufacturer’s warranty. It is advisable to check the specific product page or contact their customer service for details on warranty duration and coverage.
4. Can I split PEX-A and PEX-B pipes with the same tool?
Yes, most mechanical splitting tools work on both PEX-A (expansion method) and PEX-B (crimp method) pipes. The difference lies in the flexibility and memory of the pipe, but the physical act of splitting the wall is similar for both types.
5. What size PEX pipes can be split?
Standard manual splitting tools typically handle 1/2-inch, 3/4-inch, and 1-inch PEX pipes. For larger commercial sizes (1.5-inch or above), you may need specialized industrial equipment or a different removal strategy.
6. Is it legal to reuse split PEX pipe?
No. Once PEX pipe is split, removed, or significantly manipulated, it cannot be reused for potable water systems. Building codes require new, intact piping for installations to ensure safety and prevent leaks.
Conclusion
Finding the right Moore Plumbing Supply split up machine for Pex Pipe is about more than just buying a tool; it is about investing in efficiency and safety. By choosing high-quality equipment and following proper techniques, you can simplify the removal process and protect your workspace from unnecessary damage.
Remember, the key to successful plumbing work lies in preparation and using the right tool for the job. Whether you are a seasoned pro or a weekend warrior, having a reliable splitting tool in your arsenal makes a significant difference.
