What is a 3-way tap?

A 3-way tap is a modern kitchen faucet that combines hot water, cold water, and filtered water in a single tap. Separate internal pipes ensure that the filtered water is hygienically separated from the tap water. Compared to an extra 1-way tap for filtered water, this not only saves space but also avoids a second hole in the countertop and ensures a tidy kitchen design.

Functionality & Advantages of Three-Way Taps for Reverse Osmosis Systems

The three-way tap – often also referred to as an osmosis tap – is specially designed for connection to reverse osmosis systems and high-quality filter systems. Inside, two separate water lines ensure that tap water and osmosis water do not mix.

There are models with one tap and two separate water outlets, where the water is routed separately internally. Other versions have two completely separate tap outlets, so you can use tap water and osmosis water simultaneously – for example, to wash dishes in one basin while a carafe is filled with filtered water in the other.

Operation is usually via two levers or rotary handles: one controls the tap water (hot or cold), the other the filtered osmosis water. This way, both types of water are quickly and conveniently available at all times.

There are also suitable solutions for households with boilers or instantaneous water heaters. In this case, a 3-way tap with low pressure (low-pressure fittings) is used, which is specially adapted to these hot water preparation systems.

Overview of advantages:

No second hole in the countertop needed
Space-saving and visually appealing
Hygienic separation of tap water and drinking water
Perfect for reverse osmosis systems and filter systems
Wide variety of designs to match your kitchen style
Flexible use thanks to different spout and lever variants
Also available for low-pressure systems

3-way tap test winner – our recommendation for top quality

There are currently no official "test winners" in the field of 3-way taps. Nevertheless, when selecting our fittings, we ensure that they are characterized by first-class materials, precise workmanship, and durable technology. Furthermore, we attach great importance to only including products in our range that convince in terms of ease of use, design, and durability and that we ourselves at mein-wasserfilter.com have tested. This way, you can be sure that your new 3-way tap is not only an optical highlight but also functions reliably in daily use.

We attach great importance to the quality of the fitting matching the performance of your water treatment system. Therefore, we deliberately do not offer very cheap models, which often consist of inferior materials or do not remain sealed for long. Although fittings are available online for under 100 Euros, our experience shows that such products often show faster wear in practice. With our selection of high-quality 3-way taps, we ensure that you will enjoy your kitchen for a long time – and can enjoy your filtered water in the best quality.

In such cases, the customer agrees to compensate Blue Nature Services for the damage caused thereby. The customer will only choose the "Payment by invoice" option if they are willing and able to correctly adhere to the payment deadline specified on the invoice and to pay the invoice amount in full. Otherwise, the customer will choose the "Credit card", "Prepayment", or "PayPal" payment option. If the customer chooses the "Payment by invoice" option and does not pay the invoice, the customer expressly accepts the accusation of deliberately causing damage to Blue Nature Services with all the resulting legal consequences and costs. 6.
