Having discovered the benefits of copper in drinking water (see this link:
http://en.wikipedia.org/wiki/Antimicrobial_properties_of_copper I have begun adding more copper components to my fountains. You can see these at http://www.catfountains.etsy.com. In fact, most of my fountains have at least a copper spout. Copper will not corrode in water or air and in fact is an antimicrobial which helps purify water – thus its use in ancient times and in high scale home building.
Above is the 1 Cat Cat Tap and below is the 2 Cat Cat Tap.
Note that these are handmade from pure copper and that the solder is lead-free. Great for the countless cats who like to drink from the tap. You can see these and other copper elements in my fountains at http://www.etsy.com/shop/catfountains
