Cost to Install PEX Plumbing The cost to repipe a house with PEX tubing is $0.40 to $0.50 per linear foot, depending on the size of the house and the extent of replumbing you’re doing. Repiping a 2,000-square-foot home with PEX costs between $2,000 and $4,000. PEX is plastic tubing or hose with many beneficial characteristics. However, PEX has only been used for about a decade, and any health risks of using plastic water supply lines are unknown. 1. It is easy to install due to its flexibility. 2. It can be snaked behind drywall, eliminating the need to remove the drywall. 3. Because of the flexibility of PEX, it won’t burst if frozen; it will naturally expand to fit. 4. PEX cannot be installed outside because the UV light will break down the plastic, destroying the tubing. 5. It is suitable for both hot-water and cold-water lines. 6. It’s non-corrosive. 7. Rodents can chew through it. https://plumbingadvice24.com/all-about-pex-pipe-pex-pipes-for-plumbing-what-is-pex-pipe-how-to-measu...
