Air Release Valve

An essential air release valve fitted at the highest point of a dry riser to vent trapped air when the system is charged during the annual pressure test. Without one, air locks stop water reaching landing valves properly and can cause false test failures.

Key specs

• Brass body
• Automatic air release mechanism
• Compatible with standard UK dry riser air release assemblies
• Supplied ready to thread into place

When to replace

Replace whenever you see signs of corrosion, sticking, or a failed hydrostatic test. Fitting a new air release valve is a small job that keeps your building’s dry riser working as BS9990:2015 requires.
