Question:

I measured a 1.88 inch grey water pipe and a 3.48 inch in black water pipe. Is there an industry standard on what size these older RVs would have? Sewer Waste Valve 1984 Citation 34 Trailer

There is no industry standard for RVs when it comes to the pipes, except that the black water pipes are larger than the grey water pipes. We have a large selection of waste valves, and the pipe size as well as the type of fitting you need will determine which you should get. I've added a link to our page with each of our waste valves for you to take a look at.
