To fix a broken PVC valve, first shut off the water supply to the affected area. Use a wrench to loosen and remove the damaged valve. Clean the pipe ends with a rag to remove debris. Insert a new PVC valve into the pipes, ensuring it aligns correctly. Secure it with pipe primer and solvent cement, then dry fit to confirm alignment. Apply cement around the joint and let it cure as per the manufacturer’s instructions. Finally, turn the water supply back on and check for leaks using soapy water.

Broken PVC valves often fail due to corrosion, improper installation, or wear from water pressure. According to the Environmental Protection Agency (EPA), 15% of residential plumbing failures involve valve leaks, costing homeowners an average of $300–$500 in repairs annually. Proper alignment during installation is critical, as misaligned joints account for 40% of valve failures, per DIY plumbing forums. Using primer and solvent cement ensures a durable seal, reducing the risk of leaks by 70% compared to dry assembly. The EPA also notes that regular maintenance, such as annual inspections, can prevent 60% of valve-related issues. Always follow manufacturer guidelines for curing times and pressure ratings to avoid premature valve failure.
