What happens when you overfill tanks.....
I know if you overfill your fresh water tank, generally, there is an overflow and it dumps on the ground. What about your grey and black? Does it just start to come out of those things that drain there?

If your black tank has a tank flush on it, if you leave that run by mistake yes, it will overfill and will come out the vent pipe on the roof. All tanks have a vent of some type so they will drain. Be very careful you are not distracted when you use the black tank flush and forget to shut it off.
I ALWAYS SET THE TIMER on my phone!!!!!!!!!!!
Distracted dumping can end up being a real SH!TTY experience. :B- All you need is a twist on drain valve. Permanently attached it and get rid of drain cap altogether.
With valve closed and both tanks open tanks will equalize and you can allow black tank to fill with some excess grey water

My gray fills up long before the black. I put a valve on the main drain pipe where you connect the drain hose. With that valve closed I open the gray valve, wait a few second, then open the black valve to move some gray water to the black tank. Then close both valves. That gets me at least another shower before to the dump we go.
Do you have a picture of that setup?
Both of mine go to one main drain with drain valves for both tanks.
You can do this trick by just leaving the cap on the end but you will have to deal with the “extras” when you pull the cap to connect the hose at the dump.
DO NOT TRY THIS WITH JUST THE CAP IN PLACE!!!
People really should think before they post this stuff. If you want to use this method get yourself one of the twist on valves for the end of your drain line. That way you can attach the hose before you let the c r a p fly.
That valve looks better than just letting it fly...wnjj wrote:

Sounds nasty. Best left for times of desperation.swimmer_spe wrote:

- As mentioned when the black tank is getting near full it will burp when you flush.
