Review: Well built. Works great at a very affordable price. Installed in my pondless steam.Have used for 1 season with no issues
Review: From barn troughs to backyard pools, the MACGOAL 3/4" Float Valve is the quiet hero that turns chaotic refills into cruise control. Spin on the 3/4" threads, set the adjustable arm to your exact waterline, and let gravity and simple physics do the rest—no wires, no apps, no drama. The durable plastic build shrugs off rust, the automatic shutoff clicks in right as the surface kisses the set point, and suddenly your pool, pond, or livestock waterer stays topped without you hovering with a hose like a sleep-deprived lighthouse keeper. Installation is wrench-and-PTFE-tape simple; performance is “set it, forget it, brag about it.” If water had a bouncer, this would be it—calm at the door, full inside, and no overflows on the guest list.
