(AG150-002, 211212, GAP-A-FLO) ## Features - ❤ EASY TO CONNECT: Gap-A-Flo High Flow air gap (AG150-002) has a 1/4-inch FIP or 1/2-inch MIP threaded inlet and 1-1/4 inches outlet. The inlet accommodates 1/4-inch FIP or 1/2-inch threaded PVC adapters, while the outlet can accommodate 3/4-inch threaded PVC adapters. The AG150-002 provides a convenient way to install the air gap which can tilt up to 45 degrees. - ❤ STANDPIPE CONNECTION: Gap-A-Flo High Flow air gap (AG150-002) is a gravity flow device and must have an outlet poly tubing feeding directly to a drain without kinks or bends. It can be oriented in any way between 45 degrees and vertical with inlet port elevated above the outlet port. To ensure easy wall mounting, a Jiffy Clip clamp is included with the air gap. The AG150-002 air gap’s recommended flow rate is 12 gallons per minute. - ❤ SPLASH PROTECTION: The AG150-002 air gap uses rotating splash guards to assure a completely dry operation. Splash guards are an integral part of the design and can be seen through the side air gap window. During water softener operation, an initial discharge surge can create splashing. Splash shield eliminates the possibility of water splashing outside of the air gap. When designing drainage for an air gap, makes sure that P-trap is located minimum 20-inches from the top of the standpipe. - ❤ QUIET OPERATION: When water exits the air gap, depending on the design, it may flow directly into a P-trap. This can create splashing noise that may be objectionable. To avoid excessive noise, it is recommended to use 22 degrees elbow in line with standpipe to avoid direct drainage to P-trap. The pipe elbow should be located at least 12 inches from the air gap to eliminate splashback. - ❤ CERTIFICATION: The AG150-002 is UPC (Uniform Plumbing Code) Listed, IPC (International Plumbing Code) and NSF (National Sanitation Foundation) tested. The testing is conducted for every manufactured lot to ensure consistent performance. ## Images ![High Flow Rate Inline air gap with 1/4-inch FIP or 1/2-inch Thread Inlet and 5/8-inch Compression Fitting or 3/4-inch Thread Outlet.

It works as it should but you do need to keep the vent window rotated around just right or water will splash out.I will get one again if I need it. ### ⭐⭐⭐⭐⭐ Use 3/4 line out *by E***S on Reviewed in the United States on September 2, 2019* I honestly had the same thing happen as another reviewer on the regular version, water just flowed out of the gap. I was pissed. Then I got to thinking about my adapters. Sure, it was 3/4 fip out, but to a 1/2 barb. I realized the backflow made sense as the water was going from smaller id to larger id back to smaller id. I grabbed a 3/4 fip to 3/4 female pvc adapter, used a short run of 3/4 pvc from air gap to drain, and voila. Not a single drop of water out of the gap. Parts were like $6 total from hardware store, for both the drain lines pictured. So with either version, use larger diameter out than in. ### ⭐⭐⭐⭐⭐ Was a very convenient fit for my project *by A***A on Reviewed in the United States on January 16, 2022* Excellent construction, fit, and finish! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/28503671-high-flow-rate-inline-air-gap-with-1-4-inch](https://www.desertcart.co.uk/products/28503671-high-flow-rate-inline-air-gap-with-1-4-inch) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
