Now I am ready to dump tanks and after looking for a good while I find the blade valve handles tucked away under the frame but without markings.

My question is which one is black and which one is grey? Does anyone have one that is marked? I like to dump black first but am not sure which is which and the manuel Keystone sent does not cover it.

A lot of us have an adapter that fits right on the dump fitting that has clear pipe. Mine is a 45 degree one. For long term use, it allows us to see when the drain water is running clear as we dump and flush. Personally, I would not be without it, and now have accumulated two different ones.

This is one of the ones that I have: https://www.amazon.com/Camco-39847-R.../dp/B006OQ35GU

I also got one of these years ago to build my own dump hose for exactly the purpose we're discussing here: https://www.amazon.com/Camco-39432-D...dp/B000EDSSEI/ That one is my everyday quick dump hose and is still in use.

If you can't determine which handle is which, I am going to suggest that you get one of these and place it in-line when you dump. Briefly pull each handle and then you'll know for sure which handle is gray and which is black.

If you can't get one before you absolutely have to dump, bite the bullet, dump 'em all, flush and clean up extra well, and have the clear fitting on-hand for all future dumps.
