Tanks on 5th wheel, how many and how do they work?

I have had the plastic handles come off. They can be replaced easily. I have used a 1/4" wing nut screwed onto to the threaded rod temporarily to operate the valves.

I'll second the motion, to start looking through, searching youtube videos related to this. It is not realistic for anyone to provide you a tutorial on all this via an online forum, and its very unlikely anyone on here is going to know specifically how your rig is plumbed. Especially considering how old it is.

I would just do some searches on youtube, watch some videos, learn all you can that way. There are soooo many videos out there that explain how to do most anything with RVs. You are definitely on the right path, by getting a mobile RV tech out there. Hopefully you get a good one, and they will be able to help you with these things, and help you learn how these things work.

My rig also has the cables connecting the handles to the dump valves. Not crazy about that approach, but is necessary in many cases. No doubt sometime in the future, I'll have issues like what you're having with the cables, handles.

The more you can learn how these things work and get to where you can handle some repairs yourself, the better off you will be.

Well, there is no way to give you a tutorial thru words. No manual includes anything to tell you how the mechanicals function on any RV.

You will need to browse thru youtube videos for the best kind of 'free' help in the issues you have and just learn as you go!

I hope your situation improves as you move forward with the hand you are dealt..

Good luck! Mitch

Based on your description of the panel, it has 2 gray tanks 1 for the kitchen sink (galley) and the other for the bathroom.

And I’m sorry to hear of your loss. I know what you’re feeling losing your spouse.
I pray things get better for you.
Replacing or repairing the valves is not terribly difficult for anyone with basic skills. But might be a schitty job… Even a mediocre repair man, if honest, should be able to get it done for ya.

Thanks..the plastic handles are all broke and will not pull in or out. That's all I know at this point.

I've owned a few RV's with cables on dump valves. If the handles are not directly connected to the valves, like tucked neatly in a bin, a cable is usually connected to the handle to in turn pull the valve open or closed. These cables can rust and seize, so can the valves/blades themselves. Maybe you need wd40, maybe you need all new cables and valves. Someone would have to troubleshoot it.

Thanks Tyler0215...I have a mobile rv repair coming next week to repair my leaking rv toilet. Been in this rv nearly 2 weeks with no working bathroom. Argh. Unfortunately $$$ is an issue.

I have never used a Dutchman, but your tanks could be plumbed in a few different configurations, mine has the kitchen sink, bathroom sink and shower plumbed together into the grey water tank, the toilet dumps directly into the black tank, Fresh is pretty self explanatory, that's your fresh (drinking) water, some have the bathroom sink plumbed into the black tank usually because of proximity to the black tank, some larger 5th wheels and class A's have 2 grey tanks,(I don't know how they're plumbed).
As far as your monitor, it tells you how much is in each tank, Empty? 1/3, 2/3, full, the battery tells you how much charge is left in the batteries, assuming they work, blank tank gages are notoriously incorrect.
The switch that says Pump is for the pump that pumps water from your fresh tank to your faucets.
As far as your tank dump valves, you've left me in the fog, as mine doesn't have "cables", they are a blade type valve with a straight rod that pulls to open the valve and pushes in to close, I have had to replace a handle as the originals are plastic, the replacement I got is metal.

WOWZA! I think you need to call a mobile RV tech and have help with your problems.
Or find a veteran RV'er that might be willing to help.
