Tool Sets

Buy on Amazon Find on eBay

FLOW RATE: The AG200-004's maximum flow rate is 11 gallons per minute (GPM). The maximum flow rate per port is 5.5 GPM. The maximum flow rate through this air gap is the highest flow rate above which the air gap will overflow. At maximum flow rate, the air gap is dry on the outside.

INLET PORTS: The AG200-004 accepts two standard 5/8-inch inside diameter hoses from a dual dishwasher. The hoses from the dishwasher slide onto the side ports and are secured using stainless worm clamps (not included). Make sure there are no kinks in the hose and that water passes freely. Both sides of the dishwasher can be operational at the same time. This air gap is compatible with all dual dishwashers.

OUTLET PORTS: The drainage side of the air gap connects to a 7/8-inch inside diameter hose, which routes discharge water to the side drain connection on the garbage disposal. This hose is available from Home Depot (search for “PVC Disposal Discharge Hose”). When installing this hose, make sure that there is no sagging or loops. Any sagging will create standing water and will restrict the proper draining of the air gap. Secure both ends of the hose with a 1-inch stainless steel worm clamp.

THREADED BODY: The AG200-004 has a body with a thread that enables air gap mounting through a standard countertop. Countertop thickness can be up to 1-3/4 to 2-1/8 inches, and it does not require any special modification to accommodate this 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 inline 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 AG130-001 is legal to install in any state. It is UPC (Uniform Plumbing Code) Listed, IPC (International Plumbing Code) and NSF (National Sanitation Foundation) tested. These certifications assure that every product is safe to use.

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)

Buy on Amazon Find on eBay

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.

DRAINAGE CONTROL: When water exits the air gap, depending on the drainpipe design, it may flow directly into a P-trap. In some cases, this can create splashing noise that may be objectionable. To avoid excessive noise, it is recommended to use 22 degrees elbow inline with standpipe to avoid direct drainage into P-trap, but instead, let water flow on the side of the standpipe. The pipe elbow should be located at least 12 inches from the air gap to eliminate splashback.

UNIVERSAL AIR GAP: The AG180-002 is a universal air gap that can accommodate flow rates below 36 GPM. The AG18-002 tested for strength and to make sure that every joint and connection will withstand at least 40lb of force and not break. The AG180-002 can accommodate up to 5 different discharge pipes and can handle the simultaneous flow from a water softener, RO filter, condensate, and iron filter. All discharge pipes should be pointed to the center of the air gap to provide the best drainage.
