Fullway termination valve???

[rogerkathy]

What is this valve and how do I make sure it is open? This is on my new 323 MK Wildcat.

I would think your black tank valve. Probably just another name for it.

That is your black Tank drain valve. If not open it will pressurize black water storage system and cause something to fail.

So how do I know if it is open or closed? And how do open or close it? Is this the rod I pull out to drain the tank?

Yes. You need to have the tank drain open. I occasionally close it for a minute or two to get a little more water in the black tank, but I never walk away from it with the black tank valve closed.

As said, the fullway termination valve is another name for the black tank 'blade type' drain valve.

The disclaimer is there to hopefully prevent you from flushing the black tank with the drain valve closed. Should you get sidetracked while flushing, the tank could fill, bust, squirt crap (literally) out the vent pipe on the roof, or leak inside around the toilet.

A fullway termination valve is a gate valve by its proper RV name. So they are saying that the black tank dump valve must be open during the use of the black tank flush system. This is so you do not have sewage blowing out the vent on the top of your RV, breaking the black tank or coming up through the toilet. All things that you never want to happen. People tend to forget that the water in the flush system is running that is the reason for the warning.

It's also know as the flux capacitor.

Took me a while to find out (from the forum) what they were talking about when the printed that sticker. Doing a google search only brings up references to it on RV forums and sites...nowhere else. I would have been a lot simpler to just say black tank drain valve, but I guess some college boy that just got hired was trying to impress someone.

If left closed while flushing the tank won't pressurize and the only bad thing that will happen is the tank would overflow into the camper...probably come up through the open tube toilet.

After draining and flushing I always close the valve and let water run into the tank for about two minutes. Since I started following other members suggestions here I put water softener and a dash of pinesol in the tank. Having that 3-4 gallons allows complete dilution and also keeps it sloshing around as I drive down the road.

Like Scott said, it's OK to close the valve for a minute (while flushing) to allow a LITTLE water build up in the tank for a better flush of the tank. DO NOT walk away when flushing with the valve closed.

Didn't your dealer discuss the flushing procedures with you during your PDI?

[rogerkathy]

I really LOVE this forum!!! Quick responses! Much better than internet searches! I have found that there is so much nowadays for dealers to discuss with buyers that, because they are human, they don't remember everything. However, I do know I can rely on this forum to provide the answers and support I need to help me out. Even though I am an experienced camper (starting out with 2 man tents, dry camping, hauling my gear in canoes and camping on riverbanks, then working through bigger and bigger tents and ending with my 3rd bigger trailer) I find there is still a lot I don't know. Thanks for all your help!

Here's the process I use when flushing my black tank. This assumes your already hooked up to a dumping station with a clear hose fitting at the drain port.

1. Close the gray tank valve and turn on the kitchen faucet and to put some water in my gray tank.

2. If my black tank isn't full, I'll turn on the hose for the black tank rinse while the black tank valve is closed. While I'm doing this, I'll stand right next to the indicator panel and watch the black tank level.

3. The moment the full light starts to flicker, I run out and open the black tank valve. I'll let the rinse keep going as the tank drains until the rinse water runs clear.

4. Close the black tank valve again with the rinse going and return to the panel and watch the black tank level.

5. Run out and pull the black tank valve as soon as the full light starts to flicker.

6. If the water runs clean, turn off the rinse and let the remaining water drain. Repeat steps 4 & 5 untill you see no more debris coming out.

7. Close off the black tank valve and open the gray. This will both empty the gray tank and rinse your sewer hose.

8. Turn off the faucet that was turned on in step one.

9. Close the gray valve once all remaining water has drained.

You put way more faith into the preciseness of those indicator lights than I care to.

This is very hard on the dump station and the reason why more and more dump stations are charging or closing. If 10 people did this on a Sunday morning it will fill a 2000 gal dump station, not to mention the tie up it would cause. Please be considerate.
