Wow. Connections seem bad.

Not sure why they wouldn't include threaded hoses.

Definitely not doing that!

They should include fittings so that you can connect the device to your shut-off and to the flexible hose that is currently attached to the shut-off if you have that kind of setup. Apparently they used to, but it doesn't seem as though this model includes it.

Look in the one star reviews on Amazon if you want to see what I am referring to.
