Watermaker sample spout

[Muaddib1116]

I'm going to route my watermaker product line to a y-valve under the galley sink. I'd like to install a small unvalved spout into the sink that the product water would come out of, u til I switch the y-valve to the tank. Can anyone point me at a small attractive spout that would work for this?

On my previous boat, I drilled a small hole into the line going to the existing faucet spout (after the valves).
I then pushed a small diameter clear plastic hose up inside the spout until the end was almost coming out of the end, and sealed the entry spot with (I forget what kind of goop).

No extra spout needed.
