Tapco 738050-0070A Backflow Preventer Without Vent

Product Description

The TAPCO 738050-0070A is a backflow preventer without vent, designed to protect potable water supplies and fluid systems from contamination caused by backflow or back-siphonage. Backflow preventers are critical components in plumbing and HVAC hydronic systems, stopping reverse flow that could introduce non-potable water or system fluids into supply lines. This unit weighs 60.9 pounds, indicating a robust, heavy-duty construction suited for commercial or industrial plumbing applications. Licensed plumbers and mechanical contractors typically specify and install units of this class.

The TAPCO 738050-0070A is appropriate for installation in plumbing distribution systems, hydronic heating loops, irrigation supply lines, and other fluid-handling applications where backflow protection is required by code. Its vent-less design makes it suitable for installations where a standard relief vent port is not required or where vented discharge to atmosphere is not desired. Consult applicable local plumbing codes and standards such as ASSE and AWWA to confirm suitability for the intended application.
