The “air gap” faucet is a plumbing device designed to provide a siphon break for the drain collection of an undersink reverse osmosis unit.
For those who have a filter, not a reverse osmosis unit, there is absolutely no drain connection and you do not want an air gap faucet.
For those who have water softener resin cleaner, you may or may not want an air gap faucet. Air gap faucets their very own positives and negatives.
The objective of the air gap is to ensure that no water from your stopped-up sink drain can potentially be forced or siphoned backward to 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 included in the base of the faucet, instead of right to the drain pipe. The water then flows towards the opposite side in the faucet stem, where it falls right into a hole and drops by force of gravity in a 3/8″ flexible tube, on the drain pipe.
The air gap faucet itself requires, therefore, three tubes instead of one – the initial one is for your upward drain water, the first is for the downward drain water, plus a third is made for the unit’s product water, that you simply drink. Consequently it has to have got a wider base and may need a larger hole inside the sink for installation. This means a more complicated installation.
The faucet itself features a small hole in their body to ensure that 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 just not pressure-driven and even a small component of food or some other debris lodged inside the inlet of your drain connection can stop in the line and permit the reverse osmosis unit’s drain water to flow out onto the countertop.
Another frequent complaint of air gap faucet users is noisy performance. Some faucets put out a gurgling sound when the unit is filling its storage tank.
Plumbing codes in numerous areas require the usage 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 feature non-air gap models if no air gap request is manufactured.
