I've read some reviews that suggest they had trouble detecting flow direction. Even if there was no arrow pointing in the direction or the arrow was at the wrong end, all you have to do is blow on it. If the air can't get through, you have the answer. I think it's great and easy to install. Used it on a drain pump to drain excess water from low ground in the lawn.
