I have some plumbing on my overboard discharge from the y-valve thet is a real pain because of all the 90 degree fittings on it. It is where it is, so replumbing isn't an option. there is a 90 degree to the y-valve, a 90 degree to the vacuum break, a 90 degree from the break, a 90 degree to the discharge hose and a 90 degree to the thru-hull. The marine fittings are a hard 90 degrees, not radiused. Additionally, they employ the smaller ID of the barbs. Almost guaranteed to clog with the first guest offshore (not much of a problem into the tank). Any suggestions for sources for barbed 90 degree fittings that are radiused? I have never found such an animal in marine catalogs. I know that when the boat was re-commissioned, the guy installing a new mascerator tossed those fittings and used big PVC elbows. The overboard discharge doesn't have room for that and I wouldn't like PVC that close to raw water anyway. Rick D.
