Read the guide →FAQ — Under-Sink Water Systems
Answers to the most frequently asked questions in this category.
The system sits in the cabinet under the sink and isn't visible. Only the dedicated faucet remains on the countertop, and that's the big difference compared to a water bar that takes up room on the work surface.
A basic osmosis system works on water pressure alone and doesn't need electricity. Add-ons such as a water chiller or an under-sink water heater do need a power outlet under the sink.
Filtration depth — a clear advantage for the under-sink system, especially in hard-water areas. Convenience and immediacy — an advantage for the water bar. Space and electricity — an advantage for the under-sink system.
Yes. A combined under-sink system provides cold and hot filtered water from one faucet, without giving up kitchen space.
Yes. Dismantling and reinstallation are possible, and it's worth arranging in advance to make sure the new kitchen is suitable.
Two power outlets under the sink, a cabinet at least 60 cm wide, and a 35 mm hole in the countertop for the faucet. If the countertop is already in place — we do the drilling. When installing a side faucet, it's important that the siphon is installed and the kitchen faucet is working.

Wow, what an exceptional service experience!! I ordered a water system from Yaniv, including installation, and discovered an amazing professional!! He explained the water system options to me before I ordered and pointed me to the best product for me! Knowledgeable, patient and a real pro! Warmly recommended.
So far everything is fine. The technician arrived on time. He also helped replace the battery in the filter in the stairwell and reset the clock
Professional, courteous and fast
Locating a leak in a sewage line, I received courteous and professional service.
A gem of a guy! Professional and fair. He quickly located and cleared a blockage in the pipes and installed a water filter and leak detectors for me.
Yaniv was very helpful, professional, and even helped hang a shelf without charging
Amazing service, professional and available. I bought a water system and a garbage disposal from him

Why under-sink and not a water bar
- No tank on the counter and no manual filling
- No compressor making noise in the kitchen
- The system works directly from the water line — no limit on quantity and the water is always fresh
What's important to check
- The diameter of the hole in the countertop — most models require 25 mm
- Availability of a power outlet under the sink for electric models
- The water pressure in the building — in homes with low pressure we prefer a model with a storage tank
Maintenance and installation
- Filter replacement every 6 or 12 months, depending on the model and the water quality in the area
- Installation and service are carried out by a certified BEILIN H2O technician nationwide
- Includes a pressure check, drain connection and guidance
