Maestrini Brass Anti-Siphon Device Kit (25mm Hose / 10mm Vent)

Part No: 410033

Maestrini anti-siphon loop and breaker valve kit supplied with hose tails for a complete hose line anti-siphon installation. This kit is supplied with the following parts to create a working anti-siphon device:

1 x brass loop with two 1" BSPF ports and one 1/2" BSPF port (410015)

1 x brass siphon valve with one 1/2" BSPM and one 3/8" BSPF port (410043)

2 x brass 1" BSPM to 25mm hose tails (404054)

Once assembled, these give a complete anti-siphon device suitable for 25mm hose lines and a 10mm vent hose. This will only allow water to flow in the intended direction and will create a vacuum if the flow is reversed. Typical installations for an anti-siphon device are sea water intakes, exhaust injection lines and toilet systems where the equipment installed is below the waterline.
