17. Run On – Water continues to dispense out of faucet after releasing the dispense
button
Reason
“Run On” or “Carry On” is present in all Waterlogic pressure fed units without outlet solenoids.
“Run On” is defined is the amount of water that continues to dispense out of the faucet after
releasing the dispense button.
Run On exists because the tanks pressurize as water is being dispensed. Every Waterlogic tank has an
outlet restrictor to ensure the tanks remain full of water and water is controlled as it is released to the
faucet. The inlet solenoid controls flow into the tanks. The tanks will “depressurize” once the
dispense button is released the inlet solenoid closes. A small amount of water will “Run On” through
the faucet as the tank depressurizes to atmospheric conditions.
Typical “Run On” is 2-3 seconds.
“Run On” can be reduced by installing a pressure limiting device.
The amount of inlet or supply pressure directly impacts the amount of “Run On” as quantified below.
