swimming pool or water feature.

Backflow preventers can be very cheap; such as the hose connection on your home or extremely expensive depending on the hazard and volume of water needs. An air gap is the cheapest and most effective way of prevention. Check out your sinks, bathtubs, showers for a perfect example of air gap prevention.

If you have questions about water backflow safety, you can contact your water provider, public health department or a certified backflow specialist.
