Deringer™

Deringer backflow assemblies are the smallest, lightest, and only all-stainless steel backflow in the industry. Boasting the shortest lay length and lightest weight for cost-effective installation and shipping, Deringer™ provides superior corrosion resistance and minimal head loss to ensure the maximum possible water pressure after the backflow preventer. Backflow Xpress sells the most popular Deringer™ assemblies, including the 20, 20x, 30, 30x, 40, 40x, 50, and 50x models.
