PEX, or cross-linked polyethylene, has become a popular choice in many homes due to its flexibility and durability. But like any plumbing material, it can have its moments. Let’s talk about some common PEX issues, particularly PEX leaks and how to fix them.
Why is My PEX Leaking at Fittings?
PEX plumbing is known for its ease of installation and reliability, but leaks can occur, especially at the fittings. The main reasons for these leaks include improper installation, damage to the pipe or fitting or using fittings that aren’t compatible with PEX. It’s crucial to ensure that the fittings are correctly aligned and secured properly to prevent leaks.
