I am looking to replace the manual pulls for the gray and black tanks with electrically operated valves. I need to know the size of the 2 existing valves so I can order the correct size replacements.

The trailer is a 2015 Voltage 3200.

black valves are all 4". I THINK the grey is 2". If you OD of ABS is about 1/4" more than "nominal" size (ie 4" ABS is 4 1/4" OD).

Thanks for the replies, but one of you has to be right and the other wrong or maybe a combination. Have either of you actually done the valve replacement on a voltage?

Go measure yourself, then you will know.

35 years Colorado Master Plumber. I can assure you the valves are 3” & 1.5”. Sad when individuals don’t know the correct answer they just throw something out there.

Well, I got under the trailer, removed the covering and located the 2 main dump valves. The 2 valves are the same size, that being 3" and about 18" apart. both dumping into the main 3" pipe. I also have a 1.5" pipe coming from a rear gray tank that is only used for the kitchen sink and that valve is working. RV tech will be replacing the current 3" valves with electrically operated 3" valves next week.

Ditto. LOL

Also worth noting, The valve sizes are an RV industry standard, they aren't specific to a Voltage, or different sizes on various other RV.
