Frequently Asked Questions

How can it drain automatically without any electricity?
Internal float buoyancy triggers the valve, using system air pressure to discharge water automatically without power.
Will this valve cause air leakage during the drainage process?
No. The "Zero Air Loss" design seals the valve before air escapes, saving energy and pressure.
Will rust or debris in my pipes clog the drain?
The built-in stainless filter intercepts sludge and debris, protecting the valve for long-term, clog-free operation.
Do I need an electrician for the installation?
No wiring needed. Just screw it into the port for a 3-minute, "plug-and-play" setup.
