Water Pressure Reducer Upgrade - Standup 1.5

Updated

Overview

Bevi Standup 1.5 machines 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.

In this article (click to jump):

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 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. 
  • Buffer Tank is open.
If the Standup 1.5 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

  1. 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.  

SU 1.5 1.x SP Service Panel PIN enter sequence

  1. In the Filter section of the Service Panel, touch “Check Flowrate”. 

  1. Place a 1 L container under the nozzle. 
  2. 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.  

  1. 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.

  1. Power off the Bevi. 
    • Turn off power to the unit by flipping the switch on the back near where the power cord connects. 
    • With the power off, the Inlet Solenoid will be closed, stopping water from entering the Bevi.

  1. Open the door.
  2. Close the buffer tank.
    • The buffer tank valve is located on the plumbing shelf behind the co2 tank.  
    • Turn the valve 1/4 turn clockwise to close (pointed forwards).

  1. Using the Diagnostic Line, depressurize the Still output. 
    • Remove the black Still Diagnostic line from the grommet at the base of the door.  
    • Place the line into a container. 
    • Open the Still Diagnostic Valve until completely depressurized, then close the valve.

Task 2 : Remove the Plastic Water Pressure Reducer.

  1. Locate the water pressure reducer.  
    • The reducer is installed on the plumbing shelf, directly above the chiller.  
  2. Remove the red locking clips and disconnect the 3/8” tubing from both the input.and output of the plastic water pressure reducer.
    • Be sure to disconnect the 3/8” stem elbow from the output of the water pressure reducer, as it will be reused.  
  3. Cut the zip tie holding the water pressure reducer to the shelf. 
  4. Remove the pressure reducer.  

Task 3: Install the Metal Water Pressure Reducer. 

  1. Replace the tubing between the tee-fitting and the input to the water pressure reducer.  
    • The metal water pressure reducer is slightly shorter than plastic reducer. Reusing the existing tube may result in a leak.
    • Ensure the tubing is long enough that the output of the pressure reducer reaches the edge of the plumbing shelf.

  1. Connect the new longer 3/8" tube from the tee-fitting to the input of the water pressure reducer, with the black plastic cap facing to the LEFT. 
    • If the black cap is facing to the right, it may contact and interfere with the backflow preventer.  
    • Reference the raised 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.

  1. Connect the the 3/8” push to connect stem on the Water In tube to the output of the pressure reducer.  
  2. Ensure all tubing connections are fully seated.  
  3. Reinstall all red locking clips. 
  4. Install a new zip tie to secure the pressure reducer to the plumbing shelf.
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

  1. Power on the Bevi.
  2. Open the Buffer Tank valve. 
  3. Navigate back to the Service Panel.  
  4. In the Filter menu, touch “Check Flow Rate” 
  5. Place a 1 L container under the nozzle.
  6. Press and hold the Dispense button for Still water until you have filled the 1 L container. 
  7. 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. 

  1. 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.
