Caleffi Valves 553642A Editorial Review
The Caleffi 553642A AutoFill Automatic Boiler Filling Valve is a great replacement for old, crusted up fill valves. The valve is easy to install and comes with an additional gauge to ensure proper pressure settings. While some customers had issues with the pressure release popping off, this seems to be a problem with the pressure tank rather than the valve itself. Overall, the valve maintains pressure well and is a reliable option for boiler maintenance.
