When I was on the hunt for the perfect automatic float valve, I paid close attention to several key features:

  1. Material: I noticed that valves are often made from plastic or brass. Plastic is lightweight and resistant to corrosion, while brass is durable and sturdy. I opted for brass for longevity.
