Maestrini Brass Anti-Siphon Loop (1" BSP / 1/2" BSP Vent)

Part No: 410015

This Maestrini anti-siphon device is made from brass. The anti-siphon device allows fluid to flow in the intended direction but when the flow is reversed, the vacuum will operate the anti-siphon valve which will break the siphoning effect. This anti-siphon loop is used in conjunction with 410023 siphon break valve.

Typical applications for this anti-siphon loop are boat water intakes, exhaust injection lines and toilet systems where installed equipment is below the waterline.
