The Valterra RV Waste Valve, part # T1001B has an inside diameter of 1.9 inches and the outside of the port measures 2.37 inches.

I went to our warehouse and measured the waste valve for you. I have attached a photo of the valve with the dimensions noted.

My handle broke off on the gray tank inside and it's not leaking. Could I replace the handle only or would I have to replace the whole valve?

@EstherG If you have the Valterra Waste Valve for RV Gray Water Tank item # T1001B, like the question above you can just replace the handle with the Extension Rod Kit for Valterra Waste Valve item # T1046-12VP.
