Eliminate the Bubbler on Elkay Drinking Fountains with Bottle Fillers

Elkay bubbler removal parts


Bubblers are notorious for harboring germs. This is why in the era of the Coronavirus, many facilities are looking for ways to disable use of the bubblers on drinking fountain units, while still permitting use of the bottle filler. Fortunately, this can be done in a couple of different ways:

  1. Covering the bubbler with a lock out kit to stop the bubbler from being accessed.
  2. Capping the line to the bubbler so water will no longer flow to the bubbler.

Learn more about the bubbler cover in our Bubbler Cover Lock Out Kit Article.

Read on to learn how to cap the line to the bubblers of Elkay combination drinking fountain bottle filler units, and what parts you will need to do so. If you want to cap or cover the bubbler hole of a unit that is not made by Elkay, read our Oasis Bubbler Removal Article or give us a call for help removing the bubbler from other manufacturer units.


Unfortunately, you cannot simply cover the drinking fountain of a combination unit because the bottle filler uses the drain as well. The pathway from the bottle filler to the fountain drain must remain open.

Directions for shutting off water to the fountain bubbler, while keeping the bottle filler in operation

  1. Shut off the water to your water cooler while completing the alteration to your cooler. 
  2. Remove all panels needed to access the lower portion of the unit. 
  3. Find the ¼ x ¼ x ⅜ inch tee fitting in the water cooler. This is where the ¼-inch water line feeds to the fountain solenoid, and a ⅜-inch line feeds to the bottle filler. Remove this tee fitting and replace it with a ¼-inch x ⅜-inch union fitting. This will reconfigure the unit to send water to the bottle filler only.
  4. Cap the ¼-inch line to the fountain solenoid with the ¼-inch line cap. This will eliminate the flow of water to the bubbler. It will also eliminate any dripping of residual water in the lines.
  5. Test the unit by turning the water back on. If everything is working properly, replace the panels.
  6. Post the free printable sign that tells patrons the bubbler is unavailable for use.

When you want to use the bubbler again, simply uncap the ¼-inch line and replace the ¼-inch x ⅜-inch union fitting with the original ¼ x ¼ x ⅜ inch tee fitting.
