The California Fire Marshal approved and listed the ENTIRE Deringer Product Line today. The approval included all sizes and models...specifically 2 1/2",3",4",6" & 8" Models 20/20x, 30/30x, 40/40x and 50/50x.
We recognize this was a big project to complete all at once and we would like to thank David and DeeDee for their assistance in making this project a success! To learn more about the deringer product line, please visit our website at backflowdirect.com |
