What is this 3rd water connection?

[Piratewithrum]

I have a city water connection (screened) and a water tank fill (open hole). I have a 3rd connection I can't find info about. It says "fresh water connection" and is screened just like the city water connection. No other travel trailers I have seen have this connection (also no walk-thru videos I saw show something similar).

What is it?

I'm thinking that sticker is in the wrong spot, Fresh water typically doesn't have the hose connection, The one by itself maybe the black tank flush ?

I looked at a few videos for your RV year and model and none of them had a black tank flush on them. Maybe a previous owner installed their own. The connection on the panel with your gravity fill is your city water connection.

If you blow up the picture, It looks like the sticker says something about the flush .

Agree, my TT has a similar looking sticker by the black tank flush valve. It warns you to always have tanks empty and gate valves open so you do not fill the Black tank and make a sh—ty mess

Neither of those two stickers relates to a black tank flush. You can open the picture in a higher resolution instead of just expanding it. You can read the wording very easily that way.

It just states to keep the dump valves closed at all times to keep sewer gases from the sewer system from potentially entering the RV.

Here’s a picture of that sticker after I clicked on the original image on my iPad (you would probably have to right-click on the original if you are using a mouse) to open it in its own screen at a higher resolution. I then took a screenshot of the picture and cropped it down so I could re-post it here:

That is the same one that is on my black tank flush, The OP can look around inside see if they see where the hose goes.

That’s odd because that’s the same sticker I have on my RV right above my dump valves. My black tank flush connection is about four feet away from my dump valves and it has a different sticker specifically regarding how to use the flush system.

Also, the instructions on the sticker in the picture are contrary to those for flushing a black tank. My tank flush sticker states to keep the valve open. This sticker is telling the user to keep it closed.

While hooked up to sewer empty the black tank connect hose to the inlet in question. Open dump valve and turn water on. If water flows through the sewer hose then you know it is the black tank flush...

Or just look for the check valve/vacuum breaker (if the system was installed properly) that is installed for any black tank flush system. It’s probably in a cabinet about 1-1/2 feet to 2 feet above the floor. This will confirm that you do have a properly installed black tank flush system.

either the left input is for pressurized/spigot water to fill your Fresh Tank, or it's a Black Tank flush - either way, attach a water hose to it and give it a try with the sewer tanks open to see. If it fills the water tank, voila! Otherwise, it's helping to clean your black tank.

Far left, on it's own, is flush out. Far right is city water and the one in the middle is to fill your fresh water tank.

[Grumpy7159]

The fresh water connection on the left is for your black tank clean out. Connect your sewer hose to your drain pipe and fresh water to the connection on the left. Open the drain valve and then open your fresh water source. Run the fresh water until the drain water is clear. Close the fresh water valve, disconnect the fresh water and close the drain valve if you are done emptying all your tanks. If you fail to open the drain valve before supplying fresh water bad things can happen.

if it ends up not being a black tank flush, the other likely answer is an intake port for sucking anti-freeze for winterizing. That would be a good location for it especially if the water pump is anywhere near there.
My anti-freeze port looks like that and is in a similar position.

Simple. Next time you empty tanks leave black open and hook hose to it and watch the water run out the drain. Only makes sense that it is a black water tank cleaner. You would usually hear the water as it sprays the tank too.


But ummm, I could be wrong. LOL
