The Sill Mounted Double Water Inlet/Outlet combines a fresh water connection and waste water drain valve on one compact backplate, providing a neat and convenient solution for motorhomes, campervans and caravans.
Designed to mount underneath the vehicle sill or skirt, the kit features a durable 6mm black polypropylene backplate measuring 120mm x 100mm. This keeps both fresh and waste water connections together in an easily accessible position without requiring separate connection points around the vehicle.
The fresh water connection features a 1/2" (12mm) barbed fitting for suitable 12mm internal diameter flexible water hose. The waste water outlet uses a larger 3/4" (20mm) barbed fitting for suitable 20mm internal diameter flexible waste hose.
The fresh water connection can also provide a convenient supply point for a portable jet wash or pressure washer, provided the unit has its own suction or self-priming capability and can draw water from the vehicle's fresh water tank.
For installations where only one connection is required, we also sell separate single fresh water and single waste water sill-mounted versions.
We also sell an optional female blanking cap for the fresh water connection, which can be purchased separately here.
