Omni Gap of North Salt Lake, Utah, has released its eponymous air gap product that’s used on drainage of water softeners, filters, reverse osmosis and other devices in need of protection against syphoning. The device was named for its flexibility of uses. Made of PVC plastic, you can adapt it with many different and readily available PVC pipe and fittings. Plus, it can be installed right off the softener valve. It can also be clamped to plumbing pipes and you can run drainage tubing to any drain’s air gap.
