How to Maintain and Clean a Brass Check Valve for Longevity
2025-12-12
A Brass Check Valve is a crucial component in countless plumbing, irrigation, and industrial systems, silently preventing backflow and protecting equipment. For reliable, long-term performance, proper maintenance is non-negotiable. At Hongxiang, we engineer our valves for durability, but their lifespan is maximized with simple, regular care. This guide will walk you through the essential steps to maintain and clean your valve, ensuring it operates flawlessly for years.
Essential Maintenance & Cleaning Procedure
Regular maintenance involves inspection, cleaning, and verification of function. Follow these steps during scheduled system shutdowns.
-
Isolate and Drain: Shut off the upstream water supply and relieve all system pressure. Drain the section of pipe where the Brass Check Valve is installed.
-
Disassemble with Care: Carefully remove the valve from the line. For Hongxiang valves, unscrew the union nuts or disconnect the threaded ends as applicable. Gently disassemble the valve body to access internal parts like the disc, seat, and spring.
-
Inspect and Clean: Examine all components for wear, corrosion, or mineral deposits (scale).
-
Cleaning: Soak parts in a descaling solution (like a mild vinegar-water mix for light scale) or a specialized cleaner. Use a soft brush to gently remove debris. Never use abrasive pads or harsh chemicals that can damage the brass or sealing surfaces.
-
Inspection: Check the disc and seat for scratches or pitting. Ensure the spring is not deformed and retains its tension.
-
-
Reassemble and Test: Reassemble the valve following the correct orientation (flow arrow on the valve body). Reinstall it in the line, reopen the supply, and check for leaks. Verify that the valve allows flow in one direction only.

Brass Check Valve FAQ
Q: How often should I maintain my Brass Check Valve?
A: For residential use, an annual inspection is sufficient. In commercial or high-sediment environments (like well water or irrigation), check every 6 months. Hongxiang valves are built for low maintenance, but regular checks prevent major issues.
Q: Can I repair a leaking Brass Check Valve, or must I replace it?
A: Often, a leak is caused by debris on the seat or a worn seal. Cleaning or replacing the seal kit (if available for your model) can fix it. If the brass body itself is cracked or the seat is deeply scored, replacement is necessary. Hongxiang offers seal kits for many models to extend service life.
Q: Is a Brass Check Valve suitable for all types of water?
A: Hongxiang Brass Check Valves are ideal for potable water, heating systems, and compressed air. However, for highly aggressive chemicals or saltwater, specific material compatibility must be verified, as brass may not be suitable.
