Why You Might Need Water Filter Softener Air Gap
If your home uses a water softener system, you’ve likely considered how to safely drain discharge water. An air gap is a vital part of this setup to prevent backflow contamination. Without it, your system could siphon drains back into the water supply, leading to contamination risks and plumbing problems. You need a device that creates a reliable break between your softener’s drain line and your household plumbing, protecting your health and your home’s water system integrity.
This model is especially useful if you want a straightforward, trustworthy way to connect your water softener’s output to a drain pipe while abiding by plumbing codes. If your setup includes standard 1-1/2 inches or 2 inches standpipes, this air gap fits perfectly with minimal fuss.
First Impressions: What to Expect
Right out of the box, you’ll notice the ET115-002 is compact and thoughtfully made. The 3/4-inch female threaded inlet is ready to mate with standard PVC pipes or compatible air gap adapters. The materials feel sturdy yet lightweight, indicating durability without adding unnecessary bulk. The splash guard is integrated smartly into the design, offering peace of mind that water stays contained.
Installation hardware is minimal since the unit is designed for pressure fit or glue connections. This keeps assembly simple, even if you’re not a seasoned DIYer. The product arrives clean with clear markers for alignment, and its certification under important plumbing codes reassures you of its quality.

Technical Specifications Overview
Design & Build Quality
This air gap is built for reliability and ease of use. It features a 3/4-inch female threaded inlet, making it compatible with standard plumbing fixtures. The connection to the standpipe (1-1/2 inch or 2 inches) offers flexibility depending on your setup. It can either be glued or pressure-fitted, allowing you to choose what works best for your existing pipes.
The splash guard is one of the standout design features, ensuring no water spills or splashes during operation. This means less mess and reduced risk of water damage in your installation area. This detail was praised by customers who noted dry operation even under heavy use, which is essential for installations close to flooring or cabinetry.
One reviewer mentioned:
"Installation was straightforward, and it has stayed dry with no leaks or splashbacks. It’s a solid piece that feels like it will last."
The unit is made from durable plastic that resists corrosion and wear over time. Its certification under UPC and IPC plumbing codes guarantees it meets industry standards, giving you peace of mind that you’re installing a safe and compliant component.
Real-World Performance
When installed correctly, this air gap performs admirably. The recommended installation height, at least 18 inches above your P-Trap, helps avoid splashes from backflow water. The device handles flow rates from as low as 0.5 gallons per minute up to 9 gallons per minute without water escaping the air gap, making it reliable for a range of softener system outputs.
One homeowner shared how they replaced an older unit with this one: "Since installation, I haven’t had a single drop splash or leak. The air gap maintains a dry outside surface even when the water softener cycles at peak flow."
Additionally, the air gap supports up to 15 gallons per minute capacity when connected correctly—well over normal household softener discharge rates—so it’s ready for heavier use if needed. The threaded connection and ability to fit various standpipe sizes make aligning it with your drain system less stressful.

What Makes It Stand Out?
Compared to similar water softener air gaps on the market, the ET115-002 shines for its effective splash guard design and flexible standpipe fit. While some competitors offer only one fixed pipe size, this model works with both 1-1/2 inch and 2-inch standpipes thanks to coupler compatibility. This ability simplifies replacement or upgrading existing setups without the need for extensive plumbing modifications.
Other brands sometimes lack tested certifications, but this air gap meets Uniform Plumbing Code (UPC) and International Plumbing Code (IPC) listings, offering assurances about safety and performance. Some alternatives may not have undergone per-lot testing like this one, which increases confidence that each unit performs consistently.
That said, a few comparable products include extra adapters or fittings for more complicated installations. If your system has unusual dimensions or requires nonstandard plumbing connections, you might consider those. But overall, the ET115-002 offers balanced performance, certification backing, and versatile installation options that many homeowners and professionals appreciate.

Design Strengths and Trade-Offs
Who Is It For?

DIY enthusiasts who handle plumbing repairs or upgrades will find the simple installation design helpful. Plumbers and technicians recommending or installing water softeners could also select this air gap as a dependable choice for clients, thanks to its certifications and adaptable fit.
