How do I install Whisper if I don't have access to the water inlet on my toilet?

If you don't have access to the water inlet on your toilet you'll need to purchase this T-adapter.

It connects to the water supply valve on the wall instead of the water inlet on your toilet. Standard water supply valves use a 3/8" fitting. To be 100% sure of compatibility, check with your local hardware store and bring the white Whisper hose (3/8 fitting) to be sure.
