REDI Ario Air-Admittance Valve

The REDI Ario is a specialized plumbing vent valve designed to balance pressure within drainage stacks, prevent trap siphonage, and stop unwanted odors from escaping into living spaces.

Key Features

• Multi-diameter compatibility — fits pipe sizes from 75mm to 110mm
• Flexible installation — can be mounted vertically, horizontally, or at an angle, indoors or outdoors
• Wind-insensitive — performs consistently regardless of external wind conditions
