• For a full overview of how SeltzaHub and SeltzaTap/SeltzaTap Compact work together please take a look at our How It Works page.

• SeltzaHub
• Faucet (e.g. SeltzaTap)
• CO2 canister
• Electrical outlet under sink

• If product is in stock: most customers receive their order within 1-2 weeks, but delivery times are not guaranteed.
• If product is out of stock: the estimated timing is shown below the pre-order purchase button. Please note this is a best-estimate and not a guarantee.

• Each of Seltza's product specs are provided on the individual product page by clicking the button marked "specifications."

• We estimate 50% of our customers install the system themselves and 50% use a plumber to install.
• Some customers have reported installing the system within 30mins and others a few hours. We believe it depends on your experience and comfort with such processes.
• Be sure to review how to properly use quick-connect fittings - there are many videos online.

• Seltza provides a 1 year warranty, as well as ongoing support if issues arise.
• Seltza provides a 100 day trial with free returns, if the carbonation does not meet your expectations.
• Other return information can be found in the Refund Policy

SeltzaHub is meant to be placed under the counter. The dimensions of SeltzaHub are below. Please confirm you have enough free space under your counter.

• Height: 40cm (15 3/4")
• Width:  23cm (9 1/4")
• Depth: 43cm (17")

• SeltzaHub does not include a filter.
• The SeltzaRO Water Filter is available for purchase.
• If you already have a filter, most are compatible with the SeltzaHub

• Yes, water filters, including RO filters, can be installed before SeltzaHub.
• It's important to ensure your filter has an outgoing pressure of minimum 20psi.

• Yes, softened water is ok for SeltzaHub. SetlzaHub does not include cooper which makes it safe for use with softened water.

• Generally venting is not required for SeltzaHub. The SeltzaHub design produces very little heat making it safe to install under the sink without ventilation.

• Yes, a standard 120v electrical outlet is required.

• The Hub unit does not require maintenance.

• TR21-4 (threaded SodaStream style)
• CGA-320 (5, 10, 20lbs)

• We recommend the largest tank that you can fit in your space. The larger the tank the lower the price per glass of Seltza water.
• Common tank size are SodaStream bottles, 5lbs, 10lbs and 20lbs tanks.

• There is no specific distance limitation when installing your CO2 tank. Customers have installed CO2 beside SeltzaHub, in a corner cabinet, or even in the basement with a hole drilled through the bottom of the cabinet.
• There is a booster pump in the SeltzaHub for sparkling water. Note that there is no booster pump for the chilled-still and ambient-still lines, so they could experience a flow-rate drop when the Hub is further away than 10 ft.
• If you plan to install your CO2 further than 3 ft from the Hub, contact us for specs on what tubing you will need to purchase.

• CO2 tanks (5, 10, 20lbs) can be purchased at home brew, beverage gas, hydroponic, and wine-making shops.

• When your CO2 canister has run out of gas you will be required to replace/exchange it. The CO2 canister is connected externally and replacing it is a simple process.
• The washer inside the tank's CGA-320 regulator adapter also needs occasional replacement. Often people do this when exchanging their tank.

• Some third-party faucets will work with the SeltzaHub. In our experience most of those are beverage faucets that will provide the sparkling water only.
• Some third-party faucets do not produce an adequate level of carbonation. We recommend emailing us at hello@seltzatap.com to discuss what faucet you hope to use.

• The cartridge is a wear part that requires occasional replacement. This is a simple task.

Keep your extra parts!

• If you have a spare faucet cartridge, keep it for future maintenance use.
• If you have a Compact Tap you have optional aerators to adjust carbonation and flow.

• It's key to ensure lines are fully inserted into fittings.
• Quick connect fittings need to be inserted past the point of pressure (approx 5/8" deep) for a perfect seal.
• For disconnecting & reconnecting, there are many videos online that show how to use quick connect fittings to prevent any damage.

Here are some tips for finding the right carbonation for you:

• After the installation start-up process, allow a few days for the Hub to fully carbonate. Use/flush the sparkling water during this time.

• Always run the sparkling line for a second before putting your glass under it. This will flush out the water sitting in the line.

• Increase CO2 pressure (max 75psi). Recommend starting at 65psi and adjust as needed.

• Decrease the internal Hub temperature to 2 degrees celsius. Recommend starting at 4 degrees and adjust as needed.

Note adjustments can take time and flushing to experience the new level of carbonation.

• Complete an aerator replacement, as shown in this 1 min video? https://youtube.com/shorts/CKDvw5Pn3zw?feature=share
• Contact us if you don't have our latest and greatest aerator!

• The valve on the left hand side may not be fully seated. Adjust - there is a quiet "click" - and the dripping should stop.
• If dripping persists please contact hello@seltzatap.com and we will help you out!

• Make sure the regulator is turned the right direction: clockwise to increase pressure. This can seem counterintuitive.
• Confirm that the tank is turned fully on and that there is adequate CO2 in the tank.
• Check the washer inside the CGA-320 (large tank) adapter for damage.
