Y-valve Installation Advice and Troubleshooting
All waste plumbing hoses should be kept as short and straight as possible with no dips where waste could collect. The diverter valve should be located for easy access to the selector handle and free of other stored stuff that could bump the handle. The handle positions should be clearly marked for no confusion as to tank or overboard. Before mounting, make sure there is enough room for all three hose fittings and hose bends. Use 120- or 90-degree hose fittings where necessary to prevent tight bends in discharge hoses, and make sure to use the correct reinforced hose designed for sanitation systems.
