works better than expected
was skeptical about how well this inline valve would hold up for our boat setup since older ones gave trouble, but it actually keeps the line primed nicely and stops any drain back. packaging was a bit crumpled when the order arrived, but the part itself fit the one inch pipe smoothly.
