PEX fittings are known for their durability and reliability, but like any plumbing system, they can experience leaks. The frequency of PEX fitting leaks depends on various factors such as the quality of the fittings, installation techniques, and water pressure. However, PEX fittings are generally less prone to leaks than traditional copper or PVC pipes. With proper installation and maintenance, PEX fittings can last for decades without any leaks. If you suspect a leak in your PEX system, it’s best to contact a professional plumber to diagnose and repair the issue. At 5 Star Best Plumbing, our specialists are trained and experienced in all aspects of plumbing services, including PEX installation, water heater repair, and repiping services.
