Rinnai A Series 17i Water Servo with Flow Sensor (PA-404 17)
The water servo with flow sensor on a Rinnai A Series 17i water heater does two connected jobs: it detects when water is flowing through the appliance to trigger ignition, and it works with the servo mechanism to help regulate outlet temperature as demand changes. Combining both functions in one assembly keeps flow detection and temperature control working from the same reliable signal.
This genuine Rinnai component is made to the original specification, restoring accurate flow detection and servo control where the existing assembly has worn or degraded. Fitting the genuine part as part of servicing helps the appliance ignite promptly and maintain stable outlet temperature.
⚠ Important: Installation and servicing must be carried out by a qualified technician familiar with Rinnai products. Turn off the gas supply and disconnect power before beginning any servicing.

Rinnai A Series 17i gas water heaters.
Scheduled servicing and preventative maintenance.
Qualified technicians familiar with Rinnai products.
Repairing ignition or temperature regulation faults.
Common Problems This Part Will Fix
Appliance Fails to Ignite on Demand: Restores accurate flow detection triggering ignition.
Fluctuating Outlet Water Temperature: Restores consistent servo control where the assembly has worn.
Delayed Response to Hot Water Demand: Fixes lag caused by an unreliable flow reading.
Poor Temperature Regulation Under Demand: Addresses faults affecting the appliance's ability to hold a set temperature.
Why Buy This Product?
Ignition delays and inconsistent outlet temperature on a 17i often trace back to this combined servo and flow sensor assembly, since it's what tells the control board demand has started and then helps regulate output afterwards. Fitting the genuine part restores both functions to Rinnai's original standard in one component.
