Description

Bevi is transitioning from the use of a plastic fitting to a metal fitting on the waterblock. This will decrease the likelihood of a leak in the field.

FAQs

• Why does the plastic fitting need to be replaced?
  • The plastic fittings currently installed on the waterblock have shown to be the cause of leaks in the field. 
• How long after installation does the fitting typically fail?

• There is no indication which fittings fail and when.
• Is there a chance that the metal fittings will have the same issue?

• Bevi tested the metal fittings and was not able to invoke any failures when installed in accordance with the procedure below.
• Which Standup units need this fitting replacement?

• Only the V1.0 and V.75 Units need to have the fitting replaced on the waterblock. V1.5 units do not have waterblocks.

Required Tools and Materials

• Water Block Assembly w/Metal Fitting: P/N 720-0164 (formerly 107645-01) 

(if performing full water block assembly replacement)

• Brass Garden Hose Adapter, ⅜” Tube x ¾” FGH: P/N 720-0195 (formerly 350-0113)

(if performing only fitting replacement)

Remediation Process

Initial Inspection of Fitting

• Inspect the brass fitting for the face seal, O-ring, and collet.

Countertop

• Turn off water to the system.
• Dispense water from the head unit to relieve pressure
• Locate the water block near the filter in the cabinet.

• Remove the (2) red locking clips on either side of the waterblock and detach the tubing from the fittings.

• Remove the waterblock from the system and remove the plastic fitting.

• Check the threads on the waterblock. If any are broken, replace the entire waterblock.

• Inspect the tubing on either side of the waterblock fittings. If worn, either replace or cut the current tube to a fresh portion of the tube.

NOTE: Do not cut tube at an angle

• After the tubing has been inspected, mark the tube used for the fitting ⅞” (.875”) from the cut end. This step will ensure full insertion of the tubing into the fitting when the water block is reinstalled.

• Set the gallon setting on the waterblock to 3.

NOTE: The 3 and 8 look very similar in the small script on the waterblock, so double check that the arrow is pointing towards the 3.

• Tighten metal fitting until hand tight and mark the waterblock and fitting to indicate this position. Then tighten ¼ to ½ turn past the first resistance. The measured gap between fitting and waterblock should be between 0.18” and 0.20”.

• Reinstall the waterblock with the new fitting in the cabinet and reconnect the (2) red locking clips. 
• The arrow on the waterblock points in the direction of waterflow, which should be into the filter.

NOTE: After reinserting the waterblock, the tube markings created earlier should be visible at the edge of the fitting

• Turn on the water and observe the waterblock. Check for drips over the course of 5 minutes. If any drips are present, tighten the fitting an additional ¼ turn. If drips are still present, call tech support. 

Standup

• Turn off water to the system.
• Dispense water from the Bevi to relieve pressure
• Locate the water block near the filter in the unit.

• Follow the same procedure detailed above for replacement of the waterblock

• Final installation of the waterblock in the standup unit with the metal fitting
