Note to New Buyers and Current Owners
on August 9, 2009
I have had this water bowl for my dogs for about a year now, and it has been fantastic up until a few months ago, when it started to overflow. This occurred about the same time we got a new Anatolian Shepherd, so I just figured she had broken something in it. So I took the unit apart, and as like others have said, it is a very simple system, with a float on a lever, with a small rubber stopper, that presses up again the incoming water hole, and when there is sufficient pressure (ie.. the water bowl is full, lifting up the float) it shuts off the water supply by pressure. When I took the unit apart and looked at the rubber stopper, I noticed that the rubber now had an indentation in it. The incoming water hole funnels your garden hose down to about a 1/16-1/8" hole, so it comes through in a pretty high pressure. Well, apparently, the manufacturer expects this rubber stopper to have a pretty short lifespan, as if you look at the clip that connects the float to the assembly, there is a SPARE RUBBER STOPPER! You just pop out the old stopper, and put in the new stopper. Overflow problem solved!
SO if you can put a pressure regulator on your hose before the water bowl, to lower your water pressure, you will definitely maximize the lifespan of this item. However, it appears that it does in fact have a limited lifespan, that the manufacturer is aware of, but does not make well known, unfortunately.
Otherwise, it is great item, that does exactly as it advertises.
