The answer to 'why is my zone control system leaking water' is that a leaking zone control system is often caused by a problem with the condensate drain line or the zone control unit itself. Common issues include a clogged or damaged drain line, a malfunctioning pump, or a problem with the zone control valve or actuator.
If the zone control system is leaking, you may notice water pooling around the unit or dripping from the system. This can be a sign of a more serious issue that requires prompt attention to prevent further damage to your HVAC system and home. In some cases, the leak may be caused by a simple problem that you can fix yourself, such as a clogged drain line. However, if the issue is with the zone control unit or other components, it's best to call a professional HVAC technician to diagnose and repair the problem.
