Pre-assembled double rotating waste valve that combines your RV's black and gray tank drains into a single T-configuration, cutting your dump time in half. Rotate each valve to the angle that works best for your setup, then connect your sewer hose to the included bayonet cap fitting.
The Valterra T18 is a San Tee double rotating waste valve assembly that merges the flow of wastewater from your black and gray tanks into one T-configured outlet. Instead of running two separate valves and hoses, you get a single connection point, cutting your dump time in half and eliminating a lot of the mess that comes with older, single-valve plumbing.
Each valve rotates independently, so you can angle them to whatever position is most convenient at your mounting location. The included bayonet-style cap covers the lug fitting when not in use and stays tethered to the assembly so it won't get lost.
T-configuration merges both tanks into one outlet
Angle each valve for easy access at your mounting spot
Integrated strap keeps the cap connected, so it won't get lost
Factory tested for leak-proof, long-lasting reliability
The 3" hub slides over your black-water line and the 1-1/2" hub slides over your gray-water line, with a 3" bayonet lug fitting for connecting your sewer hose. This valve uses hub-style connections — if your existing waste valves have spigot ends instead, look for Valterra's T18B kit instead. Part Number: T18 | Configuration: 3" Hub x 1-1/2" Hub x 3" Bayonet Cap
ABS solvent cement is required for installation and is sold separately. Confirm your existing waste valve connections are hub-style, not spigot-style, before ordering.
