Does your household go through a 12-pack of soda every week?

If so, have you ever calculated what that costs over five years?

We did.

Our latest article compares buying one 12-pack of 355 mL cans every week with making the equivalent amount of soda at home using:

SodaStream Pepsi or Orange flavouring
A refillable 5 lb CO₂ cylinder
A carbonation machine
A CO₂ cylinder adapter

One year ago, Rapid CO₂ officially opened its doors.

Like most small business owners, we had a lot of excitement... and just as many unknowns.

Over the past year we've had the privilege of meeting thousands of people across Ottawa—from home brewers and aquarium enthusiasts to restaurant owners, welders, facility managers, and firefighters.

One thing we've learned is that this business has never really been about CO₂ cylinders.

It's about the people behind them.

We've been incredibly fortunate that so many of you have recommended us to friends, family, coworkers, and fellow hobbyists. Those referrals have helped us grow far more than any advertising campaign ever could.

Thank you for trusting us, challenging us with great questions, sharing your projects, and helping us become part of Ottawa's CO₂ community.

We're just getting started.

Here's to Year Two.

Most of our growth over the past year hasn't come from advertising.

It's come from you.

Customers telling friends about us.

Home brewers recommending us to other brewers.

Aquarium hobbyists sharing where they get their CO₂ refilled.

Restaurant owners helping other local businesses.

That means a lot to us, and we'd like to say thank you.

We're excited to introduce the Rapid CO₂ Referral Club.

Here's how it works:

• Join for free (just reply YES or ask during your next visit)
• Refer a friend to Rapid CO₂
• They receive $10 off their first CO₂ refill
• After their first refill, you receive a $10 refill reward
• There is no limit to the number of people you can refer.

Whether you use CO₂ for home brewing, kegerators, aquariums, SodaStream, welding, fire extinguishers, or beverage dispensing, we'd love to welcome your friends too.

Have you noticed your fire extinguisher pressure gauge slowly dropping?

A fire extinguisher can lose pressure for several reasons:

• Aging seals
• Valve leaks
• Accidental discharge
• Physical damage
• Extreme temperatures

The good news is that many units can be serviced if the issue is caught early.

We put together a guide explaining the most common causes of pressure loss and what steps you should take next.

Got old or expired fire extinguishers sitting around?

ABC and CO₂ extinguishers shouldn’t be thrown in regular garbage because they’re still pressurized and may contain chemical agents.

At Rapid CO₂ in Ottawa, we safely:
• Depressurize extinguishers
• Recycle metal components
• Repurpose certain units for training or parts

Fire extinguisher disposal is available for $8.50 per unit and units can be dropped off directly at our facility.

If you use SodaStream regularly, there’s a much cheaper way to refill your cylinders.

With a 5 lb or 20 lb CO₂ tank and the right adapter, you can refill your own cylinders at home and avoid exchange costs altogether.

You’ll need:
• CO₂ tank (hydro tested every 5 years)
• CGA320 to TR21-4 refill adapter
• Scale for safe filling

We break down the full setup here.

We also provide CO₂ refills and hydro testing in Ottawa.
