When you are dealing with fluids that can cause pollution, you want to do everything you can to ensure that the local water supply does not become contaminated. Many states require some sort of backflow prevention to ensure that their water stays safe. Our non-syphon air gap return systems protect against polluted water returning to a city system.

Benefits of the Rema Non-syphon Return System include:

  • Protection against water pollution.
  • Engineered to meet all code requirements.
  • An easy-to-maintain mechanical system.
  • A float system with simple maintenance. Since the largest part of the float assembly is outside the tank, it’s easy to work on when necessary.
  • No need to use backflow preventers.

Rema non-syphon return systems use mechanical components instead of electrical ones to reduce the incidence of costly repairs. Inside each tank, there is a hollow copper ball attached to a rod. The rod, in turn, extends out of the tank and attaches to a second rod. The water level inside the tank controls when the tank allows liquids in and when it is shut.

Think of the operation of the tank the way a standard toilet bowl works. As the water drains from the tank, the float ball lowers to allow fresh water in to refill it. When the water level is high, the float ball’s level is, too, to shut off the water valve and avoid the risk of overflow.

The design includes a gap between your water source and the tank’s filling port, making a backflow of potentially polluted water impossible. You can rest easy knowing that your tank is compliant with laws and less likely to cause dangerous pollution.

Rema’s non-syphon systems are available in both horizontal and vertical setups. The vertical setup is an excellent space saver, with a footprint of just 18 inches. It’s economical and sturdy and will retrofit with most existing boiler systems.
