No doubt this thing is made well. No complaints there. I will say that the rubber gasket is not a great match for this. You are forced to leave the locking nut a little bit looser than you would like, otherwise the rubber gasket will bleed/ squeeze out from around the nut. Since this is not a high pressure/ sealed line, it is fine. There is not a back flow flap in this. It has the pegs in it for one to be snapped in, but it does not come equipped with it. Mine is installed well above the water line so that is not an issue unless a bug builds a nest in there and plugs it up.I am very happy with this product.
