Preventative + Proactive Steps for Fountain Soda Machine Care

by Barbara Lee on November 6

There is nothing worse than serving – or being served – a glass of fountain pop that just doesn’t taste … right. It frustrates customers, and it frustrates the bar or restaurant pouring it! That’s why preventative, proactive maintenance on your fountain machine is essential for the best beverage service across the board. There are five steps to the ultimate quality drink – here’s what they are and how to manage each.


Preventative + Proactive Steps for Fountain Soda Machine Care

For many people, the refreshing, effervescent tang of soda’s bubbles is why they’re fans of soft drinks in the first place. If the pop you’re pouring is flat, check your CO2 tank. Is the valve open? Are the pressure regulators properly set?

  • The primary regulator on the tank should be between 100 – 110psi
  • The secondary regulator (on or near the syrup pump board) should be set to 60psi

Pro Tip: CO2 tanks should be stored in the coolest part of your establishment, preferably at 70 degrees, and securely fastened in the upright position.


If your fountain selections are warm, adding ice to a glass before serving it isn’t a solution! If you’re experiencing fluctuating temps of your soda, try flushing the lines at the start of each day. Ensure your drinks are at 40• F or below for optimal serving. Next, ensure your ice bin is at least a third of the way full and in contact with the cold plate. Clean and drain your ice bins every single night.

Pro Tip: Consider where your syrup rack is located in the back of the house. Remove it from any heat source or direct sunlight.

If your product doesn’t taste right, determine first if it’s a single flavor or every beverage on the machine. If it’s a single valve, check the quantity of the bag-in-box (BIB) and its shelf life. Clean that particular line and nozzles. If the taste is off across the entire machine, check the water filtration cartridge for replacement before cleaning and flushing each line. If something still isn’t right, be sure to check the quality of ice to see if that is the culprit.

Pro Tip: Disconnect the syrup lines from the BIB units, shake out any residual liquid, and soak the connectors in sanitizer solution as part of your weekly task list.


As someone accustomed to pouring fountain beverages often, you can likely spot an inferior glass of pop a mile away without even tasting it. Syrup should be less than 75 days from manufacturing date or best-by date listed on BIB units. Replace empty boxes quickly, ensuring the correct line connection each and every time.

Pro Tip: Establish a shelving system for all syrups on your BIB rack that’s consistent in your location. If you have Pepsi in the upper left-hand corner for example, always replace it in the same spot to prevent mix-ups when staff members are replacing empty syrups on the fly.


The priority of sanitation in the food and beverage industry is second to none. The standards you have for cleanliness and order in your establishment impact your fountain system, too. The cleaner the better, always. Clean your nozzles and diffusers daily. Flush drains with warm (never boiling!) water. Clean your ice chutes, bins, and drip pans daily. Make sure your glassware is clean and stored appropriately.

Pro Tip: Create an all-encompassing cleaning and sanitizing manual or procedural handbook for your business that lists daily, weekly, and monthly priorities and train all staff on its importance.
