This waste water wye (Y) or ell (L) allows for your gray water (sink, shower) and black water (toilet) to flow together and then continue on through additional piping before reaching the hose connection.
Both the 3" black waste side and the 1-1/2" gray water side are flanged. The flanges are designed to bolt to modern Valterra slide valves.
Instead of a hose connection outlet, the outlet is a standard 3" plumbing spigot which fits inside a standard hub. We offer another version, VTS-993, if you want to immediately connect a sewer hose to this ell.
We recommend purchasing a 3" valve and a 1-1/2" valve at the same time.
