Jabsco, Vented Loop, 1-1/2"
Jabsco's 1-1/2" (38mm) vented loop stops water from siphoning into your boat by way its toilet seacocks/thru-hulls. The loop uses one-way valve at the loops top that allows water to be pumped through the loop and out of the hull, but prevents the formation of a siphon that would allow water to flow back into your hull.
