What product are you guys using for an Autofill valve on your water features? We have been using the Hudson Valve, primarily. Floats don't work with pondless water features, and that's mostly what we install these days. I find the hudson valve to be pretty effective but it's not quite perfect for pondless water features either. It has to be set up so that nothing is touching the bottom of it for the product to work right. And that's hard to accomplish when you are placing it in a pool of river rocks. I've found ways to make it work. But just trying to see what else is out there. My local suppliers don't offer anything better than the Hudson valve. But surely someone out there is using something that works better.
