There has been one product that has been a best-seller for 8 years in a row at GregRobert Pet Supplies. Picture to the right is the Little Giant Everfull Pet Waterer.
This is an automatic dog watering system that provides continuous flow of fresh water to your pet. Attach the 3/4″ hose to your garden hose or tap, turn on the tap and the bowl fills to the perfect level for drinking. The automatic float controls the water level. Galvanized.
Directions for Use:
Fasten hose to water supply and turn water on. Wait 15 minutes.
If you desire a different water level, remove the metal float cover(2 screws) and follow step #1 or step #2.
Step #1: If your pet waterer has a low water level, bend brass rod with float slightly up. (See figure A.) When you find the desired level, replace the metal float cover and fasten.
Step #2: If your pet waterer has a high water level, bend brass rod with float slightly down. (See figure B.) When you find the desired level, replace the metal float cover and fasten.
Note: Make sure that the water level in steps #1 and #2 are not too high as the float
