The “air gap” faucet is actually a plumbing device designed to supply a siphon break for the drain brand of an undersink reverse osmosis unit.
For those who have a filter, not just a reverse osmosis unit, there is not any drain connection and you may not want an air gap faucet.
For those who have reverse osmosis faucets, you may or may not want an aura gap faucet. Air gap faucets their very own advantages and disadvantages.
The purpose of the air gap is always to make sure that no water from a stopped-up sink drain can potentially be forced or siphoned backward to your reverse osmosis unit via its drain connection. The environment gap system accomplishes this by routing the unit’s drain water upward into a small trough built into the lower faucet, as an alternative to right to the drain pipe. The water then flows on the other side in the faucet stem, where it falls in to a hole and drops by force of gravity in to a 3/8″ flexible tube, for the drain pipe.
Air gap faucet itself requires, therefore, three tubes as an alternative to one – one is for your upward drain water, the first is for that downward drain water, as well as a third is made for the unit’s product water, that you drink. Because of this it needs to use a wider base and may need a larger hole from the sink for installation. And also this means a more complicated installation.
The faucet itself features a small hole in its body to ensure water can flow out on the sink or countertop in case the drain tube become clogged. This may not be an infrequent occurrence, because the drain water is not really pressure-driven or even a small bit of food or any other debris lodged within the inlet of your drain connection can stop within the line and let the reverse osmosis unit’s drain water to circulate out to the countertop.
Another frequent complaint of air gap faucet users is noisy performance. Some faucets put out a gurgling sound once the unit is filling its storage tank.
Plumbing codes in lots of areas require the application of an air gap faucet with reverse osmosis units. These requirement are often ignored.
We supply air gap faucets upon request but our standard units include non-air gap models if no air gap request is produced.
