Had one of these with a whole house console humidifier I bought several years ago. Not sure where the fill hose went to, so I had to buy another one. Was using the shower head hose (shower head removed from the hose) to fill the tanks. So I see Amazon has this and I wanted to order it. That way I won't have to forget to hook the shower head back onto the hose and someone gets a wild whipping hose in their face when they go take a shower.
