How to Replace Copper Pipe With PEX - Plumbing

Replacing old copper pipes with PEX (cross-linked polyethylene) can be a smart upgrade for your plumbing system. PEX is more flexible, resistant to corrosion, and easier to install compared to traditional copper pipes. If you’re considering this home improvement project, follow these straightforward steps for a successful transition. Before starting, gather the necessary tools and materials. You will need a pipe cutter, PEX tubing, PEX fittings, a crimping tool, and a wrenches. Make sure to have a proper safety gear such as gloves and goggles to protect yourself during the replacement process. Start by shutting off the water supply to your existing plumbing. Locate the main shut-off valve, usually found in the basement or near the water meter, and turn it off. Open the faucets to drain any remaining water from the pipes before proceeding. Next, remove the existing copper piping. Use a pipe cutter to cut through the pipe and remove any fittings that are connecting the copper sections. Take care to avoid damaging any surrounding structures or plumbing. Once the copper pipes are removed, measure the lengths of PEX tubing you will need. PEX tubing can be bent into shape, allowing you to create more complicated layouts without needing to use many fittings. Using a measuring tape, allocate sufficient lengths, ensuring that each section covers the distance between connectors while allowing for some slack. With your PEX tubing cut to size, install the PEX fittings. These fittings come in various configurations, allowing for different connections, including elbows and tees. To ensure a secure fit, slide the fitting into the end of the PEX tubing and use the crimping tool to secure it in place. Next, connect the PEX tubing to your plumbing system. If you’re connecting to existing fixtures or pipes, use appropriate connectors. Remember to double-check the compatibility of any fittings you’re using with PEX materials. After all connections are made, turn the water supply back on slowly and check for leaks. Make sure every joint is sealed properly and ensure that the newly installed PEX system is functioning correctly. Lastly, to enhance the durability of your plumbing, consider investing in quality fittings. This can significantly impact the reliability and longevity of your new piping.
