Overview
Bevi Countertops that are experiencing ongoing issues with low or slow flow from the nozzle during a dispense may be impacted by a flow restriction from the plastic 40 psi water pressure regulator. This guide will walk you through the specific symptoms and troubleshooting steps to identify if the pressure regulator is the root cause, and how to replace it with an updated metal water pressure reducer.

Symptoms
- Customer complaints of low or slow flow rate during dispense.
- Flow rate complaints did NOT begin immediately after installation.
- Issues started to present only after the machine had been in use for some time.
- If low flow symptoms are present immediately after installation, the water pressure reducer is not likely to be the cause of the issue.
Prior Troubleshooting
- Water supply has been tested to verify flow rate and pressure meet minimum requirements.
- Filter has been replaced and did not have any impact on the symptoms.
- Verified Chiller Thermostat is set to 5.
If the Bevi Countertop is experiencing these specific symptoms, and the previous troubleshooting steps have been unsuccessful in resolving the issue, please continue with the the following steps to verify if an updated metal water pressure reducer should be installed.
Required Tools & Parts
- FRU P/N #720-0312 (GEN 2, WATER PRESSURE REDUCER 3/8")
- 1 L Container
- 3/8” Tubing
- Tubing Cutters
Test the Dispense Flow Rate
- Navigate to the Service Panel.
- Touch the service icon in the upper left corner of the screen.
- Touch “Start Service”
- Enter the Service PIN to access the Service Panel.
- In the Filter section of the Service Panel, touch “Check Flowrate”.
- Place a 1 L container under the nozzle.
- Press and hold the dispense button for Still water to fill the 1 L container.
- The flow rate will be calculated based on the amount of time it takes to fill.
- If the flow rate is less than 2 LPM, or significantly lower than the previously recorded measurements, then the plastic water pressure regulator is likely restricting the flow and should be replaced with the updated metal Water Pressure Reducer (720-0312).
- Please Contact Bevi Support at 866-704-BEVI for assistance with ordering the replacement.
Once you have received the replacement Metal Water Pressure Reducer, continue with the Removal and Replacement procedure below.
Removal and Replacement Procedure
Task 1: Depressurize the Water System.
- Turn off the water supply to the Bevi Chiller.
- There should be a shut off valve located on the chiller tray, directly before the leak detection valve.
- If there is no shut off valve in the tray, locate shut off at the source water source and close.
- Place a container under the nozzle.
- From the dispense menu on the screen, pour Still water until no water is coming from the nozzle.
- With the water supply turned off, only a few drops of water should be dispensed.
Task 2 : Remove the Plastic Water Pressure Reducer.
- Locate the water pressure reducer.
- It should be located between the leak detector and the Water In fitting on the chiller.
- If the water pressure reducer is not installed between the leak detector and chiller water inlet, follow the water line back to locate.
- Remove the red locking clips and disconnect the 3/8” tubing from both the input and output of the plastic water pressure reducer.
TIP: Prior to disconnecting the tubing, wrap paper towels around the base of the leak detector to prevent it from any water that may drip.
- Remove the old water pressure reducer.
Task 3: Install the Metal Water Pressure Reducer.
- The new metal pressure reducer should be installed between the leak detector and the Water In fitting on the chiller.
- If the plastic pressure regulator was not installed in this location, it is recommended to rework the water system to the specifications shown on page 6 of the Countertop Installation Guide at this time.
- Connect the 3/8” tubing from the leak detector to the input of the water pressure reducer.
- Reference the arrow on the metal pressure reducer to verify it is installed in the correct orientation.
- The arrow should be pointing towards the chiller inlet.
- TIP: The logo text also reads in the same direction as the arrow.
- Replace the 3/8” tube between the water pressure reducer output and the Chiller “Water In”.
- WHY: The new metal pressure reducer is slightly shorter than the plastic reducer, so the tube needs to be slightly longer. The existing tube may appear to seat properly in the push to connect fitting, but it will not reliably seal inside the fitting, which can cause a leak.
- Connect the new longer tube between the water pressure reducer output and the water in on the chiller.
- Ensure all tubing connections are fully seated.
- Reinstall the red locking clips.
NOTE: The push to connect fittings on the water pressure reducer have thread sealer applied, they should not be loosened or tightened.
Task 4: Retest the Flow Rate
- Open the source water valve.
- Navigate back to the Service Panel.
- In the Filter menu, touch “Check Flow Rate”
- Place a 1 L container under the nozzle.
- Press and hold the Dispense button for Still water until you have filled the 1 L container.
- Compare the flow rate to the one recorded prior to swapping the pressure reducer.
- If the flow rate improves significantly, then the repair is complete.
- Contact Bevi Support at 866-704-2384 or support@bevi.co to have the Water Pressure Reducer Upgrade for this unit logged as completed on The Well.
- If the flow rate is not improved, further troubleshooting is required to identify the cause of the flow restriction.
- Retest the water supply to ensure it meets the flow rate and pressure requirements.
- Test the flow rate after each component of the water system and compare. If there is a significant drop in flow rate at any component, it may need to be replaced.
