The Single Waste Water Sill Mounted Drain Valve Kit provides a neat and convenient external drainage point for waste water tanks in motorhomes, campervans and caravans.
Designed to mount underneath the vehicle sill or skirt, the kit features a durable 6mm black polypropylene backplate measuring 100mm x 100mm. This creates a tidy, discreet waste water drain point that is easily accessible when you need to empty the tank.
The waste water connection features a 3/4" (20mm) barbed fitting, designed for suitable 20mm internal diameter flexible waste water hose. The integrated valve allows the waste water flow to be opened and closed directly at the sill-mounted drain point.
For installations requiring both fresh water and waste water connections in one location, we also sell a double sill-mounted version, combining both connections neatly on a single backplate.
