Help

Help! We are using the TT for the first time this weekend. We have. 318bhs. If we have sewer hook up do we need to do something so the tank does not fill? Feeling stupid

I hook up the sewer hose, and close the valve until the indicator reads 3/4 full. Then I empty the tank.I belive you want enough fluid in the tank to flush out the solids when you empty the tank, other wise, leaving the valve open could leave solids in the tank while the liquid drains out.

I don't hook up the sewer hose until we are leaving so it wont become a trip hazard or get damaged. Dump when your ready to leave or at least 1/2 to 3/4 full (more is better). Dump the black water tank first, then the gray to clean out the line. NEVER leave the black water valve open or the solids will stay in the tank and harden and it will be hard to get them out.

.
If you don't want it to fill up, keep an eye on the little lights that tell you how much is in the tanks.
Shut the water off when brushing your teeth or shaving. Same thing when taking a shower or washing dishes. Don't leave the water running as you might do at home.

You actually *do* want the tank to fill up. The black for sure. The gray is a personal preference (some leave it open for showers and stuff; others close of and dump as necessary).

The reason that you want your black tank to fill is that you need the water to float the poopies down the tube and into the hole. The poopies go down the hole. If you don't have enough water, you can build a pyramid that causes you angst, hate and woe later.

X2. Keep the black tank shut to prevent a pyramid of poop and tp. I keep the gray open until the night before, and use the gray to flush the hose after dumping the black.

on a trailer your size, it would take many days to fill the black tank. many newbies focus their fears on the black tank, when it'll be the gray tank that will fill WAY faster.

as was said, keep the black tank valve closed until you are at least 3/4 full or when you get ready to leave.
leaving the gray tank valve open, is up to you. i usually leave it closed and as it fills up, i then dump most of it but leave enough to rinse the sewer hose after dumping the black tank.

I keep both tanks closed and will usually connect the sewer line while setting up camp. I have waited to connect the sewer hose a couple of time but there have also been a time or two that I needed to move the TT closer to the sewer dump. My grey tank tends to fill up really fast so I like to empty it as needed during my stay so having the hose connected is easier for me.

I always hook up the hose as well. Valves closed until I need to dump them.
I always fill a partially full black tank with water before dumping it.

When the "full" light comes on you still have several gallons of space available.
The red wire is the FULL light.

NOTE - One light means EMPTY; the 1/3 light means NOT EMPTY; the 2/3 light means about 1/2 full; the FULL means about "7/8 full".

NEVER dump unless the 2/3 light is on (1/2 tank) and it is always better to wait till or fill to full before dumping black.

Remember, also you have a thingy that allows you to hook up a fresh water hose to flush out your tanks.

I usually keep the grey water open, but then close it the night before we leave. Then when we are packing up, I open the black water, then after that is drained, I open the grey water. After that has drained, I move the fresh water hose to the flush thingy and run fresh water through both tanks. I then close the grey and black water valves, right before turning off the water. This way there is a little fresh water in both tanks (I do not have to worry about freezing temps in my area) and I can add a bit of sanitizer.

Laura- I'm too germophobic (surprisingly- given that I don't use gloves for any of my sewer antics) to use my fresh water hose on my black tank flush. I know there are back flow preventers in-place, I still use a separate green hose for that flush.

As well, with a clear elbow at the sewer outlet, I've found that it takes 2 or 3 good emptyings in a row before I stop seeing a poop-show. I usually empty my black, close the valve, then run 4-6 minutes of water via the flush into the black tank and the empty that- repeating as necessary until I stop seeing brown come through.
