How to Clean Primo Water Dispenser?

Primo water dispensers are some of the best ones available in the market.

They are pretty efficient at what they do. You can get clean and filtered water from it. Plus, it’s really worth the price tag it comes at.

But just like any other water dispenser, Primo dispensers require regular cleaning. Failure to do so will reduce its filtration capacity, and as a result, you’ll technically be drinking unfiltered water.

But before you get worried furrows on your forehead, we are here to teach you ways to clean your Primo dispenser. So that you, your family members, or anyone who consumes water out of your primo dispenser is safe and sound and consumes healthy water.

Hopefully, by the end of the article, you’ll have no queries regarding the question, ‘how to clean my Primo dispenser?’.

Why should I clean my Primo Dispenser?

Water dispensers are built to filter water so that you can drink clean and healthy water always.

But just as with any other machine, dispensers require maintenance. And if you don’t maintain them, you are opening yourself up to tons of health problems.

That’s because unmaintained dispensers become a breeding ground for bacteria and other microorganisms. You’d have seen for yourself as well; been to places where dispensers have greenish something lying around the water bottle or the dispenser tap? Yeah, that’s a sign that the dispenser hasn’t seen cleaning hands for months.

All this can lead to different health problems.

And to avoid all those problems, it’s vital to clean your Primo dispensers regularly.

Don’t think you just need to rub a clean cloth against the stains, and the dispenser gets cleaned. There’s actual work that needs to be done.

Your Primo dispenser filters the water. This means that it contains a semi-permeable membrane that lets water particles move through it with other essential particles while holding back unnecessary particles such as germs, salts, etc.

If you don’t do a thorough cleaning of your Primo, eventually, the filter will start becoming inefficient. And your water’s quality will significantly reduce.

How often should I clean my Primo Dispenser?

Ideally, you should do the superficial cleaning with every bottle change. Clean on the insides, and make it nice and dry before putting up a new bottle.

But a thorough cleaning is advised every 3 months. And it hardly takes 30 minutes for the whole process.

Failure to do so will put everyone who consumes water from unclean Primo at risk of contracting microbial diseases.

But we are sure you won’t let that happen and follow our methods on how you should clean your Primo.

How do I clean my Primo Dispenser?

This cleaning method is applied on two types of Primo dispensers – pre-filled exchange water and self-service refill water.

If you have a deluxe bottom-loading variant, then you need not worry about cleaning that one. It comes with a self-sanitization option and doesn’t require much effort from your side.

Anyways, moving to the variants that require cleaning – you need just a few things to get your machine cleaned. And again, you just need to do this process once every three months.

All you need is the following:

  • Two table spoons of bleach (you can substitute this with 2 cups of vinegar as well)
  • One 5-gallon bottle that’s empty
  • A bucket that’s volumed at 2-gallon
  • A head screwdriver. The company recommends you get it from Philips.

Now moving unto the steps to cleaning your filter. Here’s how you do it:

  • Ensure that the machine is powered-off and isn’t attached to any electrical source. This is for your own safety.
  • Next, take the bottle away. Usually, it’ll be an empty bottle or one that’s about to end. Don’t try and take away a filled bottle as it can create a wet mess all around.
  • Move the machine away to an open place. This is to let you gain access to the back of the machine.
  • Push the water buttons to drain any water that may be left in the machine.
  • Next, take the 5-gallon bottle and fill it with bleach (or vinegar) and 2 gallons of hot water.
  • Let it mix, and then put this bottle with the mixture on the dispenser. Allow the bottle to sit there and fill the reservoirs of the dispenser completely.
  • Plug the machine in and turn it on so that the water flows through it. Let this water sit in the machine for 10 to 15 minutes before you drain it out of the machine.
  • Then drain the water out of the machine completely. Till the last drop comes out of the machine.
  • Then unplug the machine once again.
  • Then fill the same bottle with hot water and put it on the dispenser. Plug the machine in and let the hot water sit in the machine for some time. Then remove the drain plug.
  • And that’s all. Once all this water is drained, take the dispenser to its original location and installed your routine water bottle on it.

Final Words

By cleaning your machine regularly, you get clean water always. And the process is so simple.

Hopefully, the question ‘how to clean my Primo dispenser’ isn’t in your mind anymore. Following the step-by-step processes above will ensure that you get clean water and avoid the risks of contracting water-borne diseases!
