Stick this in my swamp cooler. I bought it because it's all metal (except for the plastic float). The float does not swim far enough in the water to fully close the valve. So it slows down the flow of water, but doesn't stop it. 20 minutes after you left, the water starts to overflow. I tried bending the bar, changing the position, etc. Then I found the problem. The float should have been much bigger. The float that comes with the kit almost closes the valve. NEARLY.
