The “air gap” faucet is really a plumbing device designed to provide a siphon break for that drain collection of an undersink reverse osmosis unit.
When you have a filter, not much of a reverse osmosis unit, there is no drain connection and you may not want an air gap faucet.
If you have countertop bottleless water dispenser, you may or may not want an aura gap faucet. Air gap faucets have their advantages and disadvantages.
The goal of the environment gap is to assure that no water from your stopped-up sink drain can possibly be forced or siphoned backward in your reverse osmosis unit via its drain connection. The atmosphere gap system accomplishes this by routing the unit’s drain water upward to some small trough built into the base of the faucet, instead of directly to the drain pipe. The water then flows towards the opposite side of your faucet stem, where it falls in a hole and drops by force of gravity right into a 3/8″ flexible tube, for the drain pipe.
The environment gap faucet itself requires, therefore, three tubes instead of one – the first is for that upward drain water, the initial one is for that downward drain water, as well as a third is perfect for the unit’s product water, that you simply drink. Because of this it has to have a wider base and will demand a larger hole within the sink for installation. And also this means a much more complicated installation.
The faucet itself includes a small hole within its body so that water can flow out into the sink or countertop when the drain tube become clogged. This is simply not an infrequent occurrence, ever since the drain water is just not pressure-driven or even a small bit of food or another debris lodged within the inlet of your drain connection can stop in the line and let the reverse osmosis unit’s drain water to flow out into the countertop.
Another frequent complaint of air gap faucet users is noisy performance. Some faucets put out a gurgling sound if the unit is filling its storage tank.
Plumbing codes in many areas require using an air gap faucet with reverse osmosis units. These requirement tend to be ignored.
We supply air gap faucets upon request but our standard units come with non-air gap models if no air gap request is produced.
