In order to create more storage space under my head and galley sinks, I would like to re-route the drain hoses. This would involve several 90 degree bends in 1 1/4 " tubing and I would like to use commercially available ABS plumbing fittings to make the curves. There seem to be many more types of fittings available in ABS than in bronze and there is a considerable price difference. I am planning to make the final connection to the throughhull with flexible hose. Is there any reason why ABS plastic cannot be used in this drain application? If it is not acceptable, are there any other sources for 90 degree sweep or street ell drain fittings other than bronze?
