1.5" ABS Hub used in Class A Customs Gray Water Tanks
Due to the smaller outlet it is not recommended to use this for Human Waste tanks, use with Shower - Dish Washing - Hand Washing Tanks.
Do Not over-tighten fittings damage will occur
Dump valves do not hook directly to the 3" ABS fitting, from the outlet run PVC or ABS piping to the outside of the trailer, a dump valve is added to the piping.
Please note that Class A Customs Waste Water Tanks ABS fittings are installed during the manufacturing process, this will be difficult to remove if you are needing to replace this item.
We recommend seeking a certified technician for removal and installation of ABS fitting.
Class A Customs uses a speciality adhesive during installation, we do not sell this. You will need to do an online search for available ABS/PVC adhesives to use if replacing the outlet fitting.
