Commercial soap dispensers function by pressing a lever, which pushes on a seal and allows some of the liquid soap to flow out onto the hands. Changing the soap in a commercial dispenser can seem confusing if you've never done it, but once you've learned the tricks you can finish the job in about two minutes. The soap is contained in a pliable plastic bag which has a rubber tube at one end with a plastic nozzle.

Open the Dispenser

Look underneath the soap dispenser behind the push bar and soap nozzle. You will see a small lever or bar near the wall on the bottom of the dispenser. Push this lever while gently pulling the top of the dispenser toward you. The top should swing away from the wall and hang down.

Remove the Empty Soap Bag

Look inside the dispenser. You will see an empty plastic bag with a rubber tube sticking out the bottom. The end of the rubber tube has a plastic nozzle that has been inserted into a slot in the plastic frame. Take note of how this nozzle has been inserted.

Remove the empty soap bag by sliding the nozzle out of the slot and then picking up the bag. Throw away this empty bag. Set the new soap bag on the platform where you just removed the empty one.

Insert a New Soap Bag

Slide the plastic nozzle into the slot where the old one was, making sure that you press the nozzle all the way back to secure it. Make sure the bag is seated evenly on the platform with no edges sticking out the sides, and close the front of the dispenser by swinging it back in place and pressing it firmly.

Test

Press on the soap dispenser once to make sure it is working correctly. If not, open it again and reseat the plastic nozzle. If it works correctly, use damp paper towels to clean the outside of the dispenser, removing any stray soap spills.
