Review: Well made! - Great float, Positive seal, shuts off at same level repeatedly. Has been in use for over a year with no issues at all. I no longer fear a flood in the kitchen from my dog watering bowl.
Review: Great value, and easy to install. - This floater/water stopper saved the day. Not only does it work perfectly in my fountain to stop the water flow when it gets to the top, I did not realize I was losing water because the old tank ball was missing. So thankfully, this came very quickly - it must’ve shipped as soon as I placed the order. Great service! And I love the brass fittings. This thing should outlast me. Super easy to install and make adjustments so that it fit my space. You can’t beat the price!
