VICTORY!!!

Below is a photo of a 4" Deringer 20 recently installed in Northern California. This unit is replacing an epoxy coated cast iron unit that had corroded through the body. Even when placed in a confined space like an underground vault, the Deringer's compact design can be easily installed while still leaving plenty of room for the backflow professional to be able to successfully perform the annual backflow test.
