What new technologies are influencing back flow preventer design?
8 answers
For smaller type RPZ and Dbl Check devices, I see the recent change to partial plastic bodies that will lower the cost to consumers to be helpful. The lower cost of a new installation will allow consumers to be more understanding of the requirement and need. On all devices large and small, I'd say it has to be "Cartridge Design" which enables quick and successful repairs.

I would say all of the companies are trying equally hard to come up with innovative ideas. With the National and World Wide requirements accelerating quickly, I am sure we will see many innovative changes in design, materials and clever new ideas.
