Backflow Preventer


City water check.

Most commonly located attached to the rear of the city water inlet.

The one way check valve keeps water pressure inside the plumbing when using the water pump. If your pop up is losing water out of the city water inlet when drawing from the fresh water tank, then this part is likely the issue.

1/2 inch male to 1/2 inch female piping.
