We've developed this complete kit for a drain waste collector tee in cases where you have black and gray tanks coming together at the dump valve location. This is the best practice when space allows and is the most compact option available.
The heart of the kit is a Valterra reducing tee that accepts Valterra valves on rotating flanges to allow handles to extend in any direction. The bottom of the tee body is a standard Valterra bayonet fitting for a cap and your sewer hose.
The kit includes 6 components which you will easily assemble yourself.
All kits have these 5 core components:
The 6th item in the kit is your choice. Depending on how you intend to pipe your black tank to the 3" valve on the collector, you can choose from any of these upstream connections to the 3" valve.
