How to Clean Primo Water Dispenser?

  • Primo Water Dispenser is an excellent way to provide your household with pure, tasty water every time you want it with little effort. You buy the unit once and refill the water bottle as many times as you wish. 
  • If there’s anything that requires a bit more attention, it’s maintenance. From time to time, you’ll have to clean your Primo using distilled white vinegar 1, pour the bleach, or prepare another cleaning solution to make sure your dispenser or attached bottle to the dispenser are good.  
  • The article presents the ultimate guide to cleaning your Primo dispenser and ensuring it’s completely free of hostile bacteria and other debris. 

What is Primo Water Dispenser? 

Let’s start with a brief commentary on what Primo Water Dispenser is. 

Primo Water Dispenser is composed of an outer container and a water bottle filled with water—both manufactured and prepared by the Primo brand. 

The drinking water that sits at the bottom of the unit is municipal water: filtered, purified with reverse osmosis, and added minerals for taste. 

The container unit uses a generic 3-gallon or 5-gallon water bottle. 

At the bottom of the unit sits a bottle that has a small tube placed inside. The water is then siphoned up to the top for dispensing. 

Is there anything more we need to know about the Primo water dispenser?

It’s worth mentioning that FDA confirms PET bottles (the material Primo water bottles are made of) are safe for single and repeated use. 

It means that when you have an empty 5 gallon bottle, it’s unnecessary to throw it away and buy a new one. 

You can save money and time by simply refilling it instead!

Clean your Primo 

To discourage the development of harmful bacteria in your Primo unit, ensure it’s always clean.

How often to clean:

  • water bottles, and 
  • the Primo water dispenser?

When it comes to dispensers, a throughout cleaning should come up every three months.

With bottles, we can be lazier—every six months should be enough. 

Also, you’ll be glad to know that you can do all the cleaning by yourself! 

Let’s discover how!

Empty bottle cleaning

We mentioned that cleaning your Primo bottle should take place every six months when it gets empty; you don’t want to clean the bottle with your water in it. 

Before you refill your gallon water bottles, give them a little wash to ensure you keep bacteria away from your drinking water.

Primo’s water bottles are made from polyethylene terephthalate (PET), and the FDA states PET is safe for single and repeated use. 

Important: Reusing plastic water bottles without washing them will encourage the development of some harmful bacteria. 

To ensure the highest quality water, rinse the bottle with baking soda before each use and sterilize with household bleach every six months. 

Here’s how to rinse the bottle: 

Mix one tablespoon of baking soda per gallon of water, place a cap on the bottle and shake. Rinse thoroughly and allow the bottle to air dry. 

And how to sterilize every six months:

Add half a teaspoon of household bleach per gallon of water, swish the water around and let stand for 3 minutes. Pour out and rinse the bottle until the water is clear and you detect no scent.

Cleaning water dispensers 

Besides taking care of the water bottle, clean your Primo water dispensers every three months. 

Luckily, cleaning a Primo dispenser takes only around half an hour and isn’t a costly procedure at all.

Frequently Asked Questions

Primo water originates from municipal sources, but its quality is far above this of tap water. It’s because it goes through a nine-step purification process. This method comprises filtration (water leaves behind salt, chemicals, minerals, and other impurities), UV sterilization, and mineral addition (Calcium Chloride, Potassium Bicarbonate, Magnesium Chloride) to perfect its taste. As an effect, we get highly purified, healthy, and great-tasting water.
The company claims that you can store Primo dispensers indefinitely, under one condition: keep the bottles in a cool location and out of direct sunlight.
This service is available nationwide at thousands of convenient locations. Just take the water bottle to a local store, grocery store, or gas station. Some stores will even take your used bottle and hand you a new one, so there's no need to clean it.
