The ET117-009 universal water filter air gap is designed to provide a convenient way to install an air gap into 1-1/2-inch standpipe drain. This air gap can be connected to a water filtration system using 1/4-inch flex tubing. The unique design provides a completely protected air gap without any possibility of water splashing out. The inlet accommodates flex tubing for a leak-proof installation in tight spaces. The right-angle inlet provides a convenient way of connecting discharge water tubing to a drain line through air gap.
The ET117-009 air gap is easy to use and legal to install in any state. The ET117-009 air gap is listed by UPC (Uniform Plumbing code) and tested for compliance with IPC (International Plumbing Code) and NSF standards.
