Is there a product which will automatically add water to a fountain

outdoor faucet?

Yes, most people use the float that was designed and used in the
evaporative (swamp) cooler. You hook up a water line to the float and
set the float to the desired level. This is very similar to the float
in the toilet tank. This item can be purchase at Home Depot, Lowes,
Pay N Pack, etc..
