Temporarily plugging plastic tubing is often necessary during home renovations, such as when replacing kitchen or bathroom cabinets. There are various methods to achieve this, including using push-to-connect fittings, which are suitable for copper, CPVC, and PEX plumbing pipes. These fittings typically include a stiffener, a small plastic cylinder that adds rigidity when capping PEX tubing. While relatively expensive compared to other capping methods, push-to-connect fittings offer convenience and ease of use. However, improper installation can lead to issues like water hammer, resulting in potential flood damage if left unattended. For a more permanent solution within walls, soldered fittings are recommended for DIY enthusiasts.

Push-to-connect fittings for copper, CPVC, and PEX water pipes
Push-to-connect fittings are a convenient way to temporarily cap water-supply pipes during renovations. They can be used with copper, CPVC, and PEX water pipes. These fittings are easy to install and do not require any special tools, soldering, crimping, clamps, unions, or glue. They are, however, relatively expensive compared to other capping methods.
To install push-to-connect fittings, you should first cut the pipe to the desired length. Then, if you are using CPVC pipe, you will need to clean and mark the pipe, just as you would for any other fitting connection method. For CPVC pipes, you can use ProBite ® Push Connect ® fittings, which connect the pipe in seconds without the need for crimp rings, special tools, or messy glues.
When using push-to-connect fittings with PEX tubing, you may need to use a stiffener, a small plastic cylinder that slips into the end of the pipe to provide rigidity. This is not required when using copper or CPVC pipes. Simply push the fitting onto the pipe until it snaps tight, creating a leak-free connection.
To remove the fitting, a disconnect clip or a simple plastic tool is usually required. This tool is used to depress a release collar, allowing you to slip off the fitting. It is important to always use the manufacturer's recommended tool for removal to ensure that the fitting can be safely reused if needed.

Stiffeners for PEX tubing
When undertaking plumbing work, such as a kitchen or bathroom renovation, it is often necessary to temporarily cap water-supply pipes. This can be done using push-to-connect fittings, which work with copper, CPVC, or PEX plumbing pipes.
Push-to-connect fittings often include a stiffener, a small plastic cylinder that slips into the end of the pipe to provide rigidity when capping PEX tubing. This helps to maintain the pipe's overall roundness and prevent leakage. Stiffeners are also included by default with push fittings and are intended for replacement purposes only.
Stiffeners are required when connecting 1-1/4 inch to 2-inch universal fittings to PEX, PE-RT, and HDPE pipes. SharkBite, for example, offers stiffeners that can be used with these pipe types and inserted inside 1-1/4 inch to 2-inch SharkBite Universal fittings. No special tools, crimping, glue, or soldering are needed for installation.
It is important to note that while push-to-connect fittings are convenient, they are relatively expensive compared to other capping methods. If not installed properly, excess pressure or water hammer can occur, causing the fittings to blow off and potentially leading to extensive flood damage if unattended. For a permanent capped line in a wall, soldered fittings may be a safer option.

Release features for removing fittings
To remove plastic tubing fittings, it is important to first identify the type of fitting. For example, the process for removing a compression fitting differs from that of a push-fit fitting.
Compression Fittings
Compression fittings are used extensively in plumbing for both metal and plastic pipes. They consist of a pipe with male threads, a ferrule or olive (a small ring-like component), and a compression nut that wedges the ferrule into the gap between the pipe and the fitting.
To remove a compression fitting, follow these steps:
- Use two pairs of locking pliers: one to turn the compression nut and the other to hold the pipe and prevent it from turning.
- Turn the nut counterclockwise while holding the pipe steady. This may require some effort.
- Once the nut turns, you may be able to unscrew it by hand.
- Remove the ferrule from the pipe. If it is a metal ferrule, you may need a compression ring puller, but for plastic or rubber ferrules, you can simply grip and pull it toward the end of the pipe.
Push-Fit Fittings
Push-fit fittings, also known as push-to-connect or quick-connect fittings, are designed for quick and simple installation without special tools. They are used to connect pipes made of various materials, such as PVC, CPVC, PEX, or copper.
To remove a push-fit fitting:
- Turn off the water supply to prevent anything from spilling out of the pipe.
- Locate the gripper ring, a metal ring that grips the pipe, and push it down towards the fitting body while holding the pipe in place.
- Pull out the pipe. You may need to wiggle it slightly to loosen it.
- Inspect the fitting for damage or debris, and clean it if necessary before reusing or replacing it.
Additional Tips
- When removing or installing plastic tubing, it is important to ensure that the tubing and fittings are clean and free of debris to prevent leaks and ensure a secure connection.
- For compression fittings, proper alignment is crucial to prevent leaks and damage.
- When cutting tubing, use a pipe cutter or a utility knife to ensure smooth edges, and remove any burrs or rough edges that could hinder the fitting installation.

Soldering fittings for permanent capped lines
Soldering fittings create a permanent capped line and are a safer option for DIYers than push-to-connect fittings. Before soldering, ensure you are wearing the appropriate personal protective equipment, including gloves and safety glasses.
Firstly, shut off the water supply to your house by closing the main shutoff valve. Drain any residual water and pressure from the pipes by turning on a faucet or spigot that is lower than the pipes you will be working on. This will minimise the amount of water that spills out when you cut into the pipes.
Next, cut off the water pipes using a tubing cutter or a hacksaw. If you use a hacksaw, be sure to make a clean, square cut to ensure a proper seal with the soldered fitting. File off any rough edges and smooth the pipe with emery cloth if necessary, but be careful to maintain the pipe's original roundness and diameter.
Before soldering, clean the end of the pipe with a rag to ensure it is smooth and free of old solder or other materials. Polish away any grime to ensure maximal bonding. Apply flux to the outside of the copper pipe and the inside of the end cap.
Finally, use a soldering tool to create an airtight seal between the pipe and the end cap. Note that soldering involves open flames and high temperatures and should only be performed by those with the necessary skills to complete the work safely.

Capping water-supply pipes during renovations
Capping water-supply pipes is often necessary during renovations, especially in the kitchen or bathroom. For example, when replacing cabinets, you may find that the water supply pipes extend through the back or bottom floor of a sink cabinet.
Before capping, you must shut off the water supply to the house. Locate the main shutoff valve and turn off the water there. Next, drain any residual water and pressure from the pipes by turning on a faucet that is lower than the pipes you will be working on. This will minimise the amount of water that spills out when you cut into the pipes. You can use a tubing cutter or a hacksaw to cut the pipes, but ensure that the cut is clean and square to guarantee a proper seal with the push-to-connect caps.
Push-to-connect hardware works with copper, CPVC, and PEX water pipes. Most include a stiffener—a small plastic cylinder that slips into the pipe to provide rigidity when capping PEX tubing. Copper and CPVC pipes do not require a stiffener. Push the pipe cap onto the pipe until its edge reaches the depth mark. Then, turn the water back on and check the cap connections for leaks. Push-to-connect fittings can be temporary or permanent. They usually include a release feature that allows you to remove the fitting with a special tool provided by the manufacturer.
Applying supplementary sealants can prevent leakage through microgaps. Wrap threaded connections with PTFE tape or use thread sealant pastes for permanent bonds. Before sealing caps permanently, a dry test-fitting allows adjustments. Feel for complete contact between the cap lips and pipe edges. If the fit is wobbly, stack washers or shims until it is aligned flush.
While capping is a common method for renovations, alternatives like freeze plugs may sometimes be a better option. Discuss with plumbers to determine the ideal solution for your situation.
