I used this one. Not a long hose, I suppose you could change that out. The hose wraps up inside the unit, it is a bit more stiff than I like. Works as intended, source of water outside the TT. When I said I installed 'T's, i cut the pex tubing, installed 'T' with sharkbite connections. Easy work. Local hdw store will have what you need, along with water hookup hoses.

Edit: This is an example of what I would NOT buy. Look at the pictures and you will see the box has openings, and the hose goes outside the box. In my application, that would leave my undersink area exposed to free flowing bugs etc.
