Zurn Wilkins Model 950XLTDAF
Designed to take the place of existing 2" water meters (17" lay length standard) on water connections in fire sprinkler systems to protect against both backsiphonage and backpressure of polluted water into the potable water supply. Allows the system to be upgraded to having a backflow preventer in line and still have some minor metering capability with the by-pass. This becomes an ideal retrofit product since no re-piping is necessary, making it a significant cost savings method to add backflow protection. Change out will be performed by both utility and fire protection contractors. Model 950XLTDAF shall provide protection where a potential health hazard does not exist.
