Universal Multi-Drain Air Gap for Condensates, Water Softeners and Water Filters with 1/2-inch and 3/4-inch PVC and Copper Pipe Adapters (AG180-002, GAP-A-DRAIN)

Very easy to install, but larger than expected in person. Wish the clips covered more than just 3/4" lines, but I used the zip tie version to zip tie a 1" drain line and two 1/2" drain lines to it. So far it works quite well, with a bit of water escaping when my water softerner starts its backwash and initially burps water out. I took a 6" round tube and fashioned a bit of a guard around the sides (while still maintaining air separation)

this worked great for our basement subpump.

Great product

Won’t work for our application. Max of 36 GPM in description and optimal 18 GPM. Packaged documentation says 7.8. Can’t imagine how water coming out of a 1/2 hose at anything greater than 1/2 GPM won’t completely spray out of this thing.

Hooked nicely onto my floor drain.

Works well so far
