what does this mean (flush valve)

[rp53]

look at mt TT this afternoon i must not be very observant first time I've see it and i really don't know exactly what it means, could it mean you should have your black tank valve open ?

[BandJCarm]

That's what it says.

I have my outside shower hose connected to the black tank flush inlet. I let it run sometimes (attended) with the valve closed to build up some quantity of fluid, then open valve to flush. I don't use the outside shower for anything potable.

So I'm a bad man, I guess. But that's what I do. Hard enough to get the stuff out of the black tank...........

A lot of words to say: when flushing have black tank valve open.

[rp53]

I'm not sure that is what it means to many reference to valves

They are commonly referred to as a gate valve.
Fullway termination valve is a new one to me. Must be an engineer's term.

When you use your blank tank flush, you must have the black tank valve open or the poop water will come out of the vent on your roof creating a unsanitary condition.

They can charge more for campers if they have Fullway termination valves in place of Gate valves.....please don't confuse the two just because they look the same, are made out of the exact same materials and perform the exact same function!!!

I jest of course

OK - Totally guessing here, but most units have a shutoff for the gray water tank and a shutoff for the black water tank - both leading to a capped outlet. Could the sticker be referring to the cap?

No referring to the valve. The thingy that opens/closes with the pull thingy handlemajig for the black tank.

All hoses should have a vacuum breaker at the source/post. We usually use a "Y" at the post for faucet water and a different color spare hose. Have made the mistake leaving the spare hose connected to the Black tank flush. I realized if the Black Tank filled up ,it could back flow through the "Y" into the fresh water, that is why I have vacuum breakers on all water connections.

No it won't.

The black tank is at least 40 gallons. If I pour water into it via the black tank flush when it's nowhere near full, it isn't going to even fill up until it gets close to 40 gallons. If I put in, say, 10 gallons, into a mostly empty tank and THEN open the valve, what the heck is the bad thing that will happen???????????????????????????????

What you say might happen if I walk off and forget I have the flush operating for two hours, yes. But if I don't forget and it only fills up for a bit, there should be no issue.

Nope,Crunchman is Correct,if you leave the BTF Water on long enough you will have "Black Tank Contents on Your Roof"! Erase this if it offends! Youroo!!

If your black tank flush was factory installed then it already has a vacuum breaker installed.

[dalford]

It is just a typo... the word valves after tank flush should not be there. No such thing as a tank flush valve.

[Herk7769]

Least common denominator sticker.

Safest use of turboflush is with the black tank shutoff valve open.

Sorta like:

I agree the factory would have installed one, but ... I bought my TT used and the previous owner removed the vacuum breaker valve. It must have broken (the cheap plastic ones that the factories install are know to do that). He replaced it with a 90deg fitting. I use a vacuum breaker on the fill port for the flusher.

Sorry the picture turns on its side.

I have a backflow preventer on my black water tank that I installed. I just hook my outside shower to the black water flush. I just turn on the shower cold water to flush out the black water tank and sometimes I use hot water to flush out the black water tank. I leave the valve closed so I can fill up the black tank and I usually fill the black tank three times to clean out the black tank. I also go inside and flush the toilet to put water in the black tank faster. Works for me
