Best Air Gap International in 2026

❤ EASY TO CONNECT: The AG180-002 air gap comes with pipe support adapters for 1/2-inch or 3/4-inch PVC and copper pipe connection. Snap-in retainer provides a simple way to secure 1/2-inch pipes. For larger pipes, use a pipe support adapter and a stainless-steel worm clamp. For pipes to stay in place, ensure they are secured to a support structure within 12-24 inches from the air gap. An air gap is a non-pressurized device, and therefore very little pressure is exerted on the pipes.

❤ STANDPIPE / DRAIN CONNECTION: The AG180-002 installs directly onto a 2-inch standpipe or connects securely to a floor drain using a stainless hook. This air gap can be used with plastic or metal standpipes. If needed, it can be glued in place to a plastic standpipe using regular PVC adhesive. The air gap is designed to drain up to 36 gallons per minute safely. The optimum recommended flow rate is 18 gallons per minute.

❤ SPLASH PROTECTION: The AG180-002 uses a funnel design to assure a splash-free operation. During water softener operation, an initial discharge surge can create splashing. Funnel design and side splash guards eliminate the possibility of water splashing outside of the air gap. Make sure that P-trap is located minimum 12-inches from the top of the standpipe. This is needed to avoid water splashback from the P-trap and to create static water pressure for continuous water drainage.

❤ FLOW RATE: The GAP-A-RO air gap’s maximum flow rate is 1 gallon per minute (GPM). The maximum flow rate through an air gap is the highest flow rate at which water does not splash outside of an air gap. At maximum flow rate, the air gap is dry on the outside.

❤ EASY TO CONNECT: The AG110-004 air gap’s inlet connects to 1/4-inch ID tubing from the reverse osmosis unit, while the outlet connects to 3/8-inch ID tubing which directly feeds to a standpipe through a suitable standpipe adapter.

❤ STANDPIPE CONNECTION: The AG110-004 air gap’s 3/8-inch OD outlet connects to a 3/8-inch ID poly tubing which feeds directly to a standpipe without kinks or bends. Included accessories are provided with the air gap to secure its connection to the standpipe.

❤ FLOW RATE: MR. DRAIN air gap’s maximum flow rate is 12.5 gallons per minute (GPM). The maximum flow rate through an air gap is the highest flow rate at which water does not splash outside of an air gap. At maximum flow rate, the air gap is dry on the outside.

❤ EASY TO CONNECT: MR. DRAIN air gap (AG100-001) has 1/2-inch OD inlet port for direct 1/2-inch PVC pipe connection. The 1/2-inch inlet accommodates any 1/2-inch slip joint adapters. The adapters include a threaded end, barb connection, and a quick connect for PEX tubing. Also, the inlet accommodates 5/8-inch OD tubing that can be directly inserted into the inlet. For tubing to stay in place, it needs to be attached to a support structure within 12-18 inches from the inlet port.

❤ STANDPIPE CONNECTION: MR. DRAIN air gap (AG100-001) inserts directly into the 1-1/2-inch and 2-inch standpipes. The body of the air gap provides stops to assure secure placement. This air gap can be used with plastic or metal standpipes. If needed, it can be glued in place with plastic standpipes using regular PVC adhesive. The air gap outlet is designed to pass up to 15 gallons per minute. The optimum recommended flow rate is 7 gallons per minute.
