Tired of lugging heavy seltzer cases or constantly refilling small SodaStream bottles? Moving to a continuous water carbonator is the ultimate upgrade for your kitchen or home bar. Instead of carbonating one liter at a time, these systems tap directly into your home's water line to provide an endless stream of bubbly water.

1. Choose Your System Style

There are two primary ways to achieve "endless" seltzer at home: the Countertop Benchy Sparkling Chiller and Carbonator and the Corny Keg-Based Continuous Carbonation Reactor Lid.

KegLand Benchy Sparkling: A compact unit that both chills and carbonates allowing you to serve both chilled water and chilled sparkling water side by side.

• Assembly: Pair with standard draft faucets to complete the countertop assembly, or undercounter and send to Kegland's Dual-Outlet Water Tap. 

• Best For: Renters or those who want a "plug-and-play" solution without a full kegerator. Also works great for mobile food and beverage operations.

Continuous Carbonator Corny Keg Lid: If you already own a kegerator or a fridge with room for a 1.5, 2.5, or 5 gallon keg, this is the most cost-effective setup.

• Description: You replace your standard Corny keg lid with our Keg Reactor Lid. It features a built-in float valve (similar to a toilet tank). As you pour seltzer out, the valve opens and allows fresh house water to spray into the  pressurized CO2 environment, carbonating it instantly.

• Best For: High-volume users and homebrewers who already have a draft system.

2. Understanding US Home Plumbing Connections

Connecting a carbonator to your home plumbing can feel intimidating, but modern Push-In (Duotight/John Guest) fittings make it a tool-free job. Here are the common connection types you’ll encounter:

• Under-Sink Cold Water Valve: Most US sinks use a 3/8" Compression fitting. You can easily add a "T-Valve" here that sprouts a 1/4" OD push-fit tubing to pair with Duotight fittings.

• RO Systems: Almost all home Reverse Osmosis systems use 1/4" (6.35mm) OD Tubing. Our systems are designed to "push" right into these lines.

• Standard Tubing Sizes:  1/4" (6.35mm) OD: Standard for fridge ice makers and RO systems.

  • 5/16" (8mm) OD: Common for draft beer lines and the "Sparkling Out" ports on the Benchy.

• The Pressure Regulator: Most US home water pressure is between 40–60 psi. If your house pressure is very high (80+ psi), you must use an Inline Water Regulator to prevent blowing out your carbonator's seals. If too low, you might need to add a Booster Pump to increase your mains pressure.
