Gray Water Valves

[darlingtontrio]

I am curious if gray water valves are universal in size. I have to go to Charleston tomorrow and was planning on stopping by to pick up one tomorrow if they are universal. Does any know.

I picked up a gray today. Before I left this morning I looked and my gray is 1 1/2 and the black is 3. Now comes fixing it.

Yep, gray 1 1/2"
black 3"

Mine is 1.5"

The grey water is usually 1 1/2"; the black is normally 3"

Valterra has two sizes; 1 1/2 inch and 3 inch. You would probably be OK with the 3 inch.
