The discharge port removes water from the upper valve chamber. When the valve opens, the diverter alleviates downward pressure on the diaphragm by ejecting residual water from the upper chamber. Water is usually ejected from the discharge port when the valve opens.
The discharge port may also eject water due to an unsustainable pressure build-up in the valve.
Case 1: Just a Drip
When debris is caught in the valve chamber or diverter, the diverter may not seal properly, resulting in a drip from the discharge port. Flushing the system may help remove debris from the diverter and upper valve chamber. You may also disconnect the diverter tubes to flush debris.
If flushing the system does not fix the slow-drip leaking discharge, the dome may need to be replaced. Contact Lumo Support.
Case 2: a Steady Stream
If the upper and lower chamber tubes are incorrectly installed (i.e., they do not connect to the correct ports), a steady stream of water could leak from the discharge port once the valve is under pressure.
To fix the problem, swap the tubing to the correct ports.
The Correct Diverter Tube Orientation
The long tube (upper chamber tube) extends from the wetware to the upper diverter port on the dome, closest to the control button.
The short tube (lower chamber tube) connects the lower chamber port on the wetware to the lower diverter port on the dome.
