3 Hoses under camper by stairs? 2020 Kodiak Cub 198BH

[DuckPen]

I'm NEW to trailers and the manual doesn't have pictures as to what hoses and parts are what. It assumes you know already so sorry for the stupid question.

There are 3 thin hoses coming from underneath the camper that are about 1/4" wide. There are no markings on any of them. I assume they're drain hoses? But for what? There are 3 of them. A red and white on the left and a white one further over to the right. (see picture)

When are they used?

The two together are likely low point drains.
red for hot water lines, and white for cold water lines.
The lone white would be the fresh water tank drain.

THanks SO much. All the videos and other docs showed blue and red lines. I don't have any blue lines and couldn't find anything to explain.

Issue --- the two hoses together - OK for red for hot, but the white one with it is the drain for the freshwater tank, however, the pump MUST be running or water will only drip out. Is this normal or should there be an alternate action. The manual indicates the pump should not run when the tank is dry. Nor does it say for this model if the pump has an auto shut off.
The stand-alone hose in the rear seems to do nothing. It only drips water so I don't know where thats coming from I haven't found any actions that increase that drain level. The manuals don't have any information

Don’t you have a switch for the water pump on the control panel?

Yes. However, I need to ensure that running water pump till takes dry isn't only way to empty fresh water tank.
My understanding is that the one hose under tank should gravity drain.
It's clogged most likely based on comments in this thread

Wait! What?

When you pull the drain for the fresh water tank, you don’t get water out of it? I’m confused!

The white hose next to the red hose is your cold water drain line, the red one is the hot drain line…. The one in the center is the drain for the freshwater tank (which is usually empty unless you deliberately put water in the tank). Open the faucets then open the drains. Keep in mind that those do not completely drain all the water out of the system. Don’t depend on them for complete winterization (although living in Orlando should not be an issue)…

You are correct. I have a full freshwater tank and when the tube is opened, no water comes out. There are only 2 ways to drain the tank and both require me to run the pump. 1> run faucets into gray water tank 2> open cold water tube and run pump.

I think the suggestion that the tube is clogged may be the issue. I moved the RV to a concrete pad so I can more easily crawl under and see how to remove that tube. I assume I'll be getting wet fast if that's the issue!!

That doesn’t make sense to me! The pump is connected to the fresh water tank. If there is water in the tank the pump will pump it out. Fortunately, those shut off valves are easy to replace. Cut it off and reinstall it. It’s just a pex fitting. Once you cut it off, run a wire up there… you may have some debris in there from the former owner.

Get a boroscope for your cell phone and run it down there for a look-see!

As Franktafl stated the red and white hoses that are together are your plumbing low point drains. The lone white hose would be the fresh water tank drain. The valves are ball type and when the handle lines up with the inlet and outlet the valve is fully open. Those valves are quite low and close to the ground, you could have some debris in the valve outlet. With the valves open poke a stiff wire up the valve and hose. I would suggest, putting some type of caps on the valve outlets to keep debris, bugs, etc from accumulating in the outlet tube.
Also quite important, when there is water in either hot or cold water lines through out the trailer, when you open the valves, you need to open all water faucets to allow air in the lines. Otherwise the water will only drip out. I would also suggest when you attempt to drain the fresh water tank to open the water fill cover, to also allow air to enter system.
The fresh water drain hose should be a short hose attached directly to the bottom of the tank. Fairly rare, but I have seen foam or plastic debris in water systems from careless workers at the factory. That usually occurs with new trailers. Which, I did not see if you said your rig is new or used.

Hello everyone. YEA! I crawled under the carriage with my trusty wire hanger and did a poke up the fresh water tube. I will not discuss the crud that intially came out onto my hand. However, that WAS the issue and the fresh water tank is now draining!!!
I'm going to run a few cleaning fills and let it drain to ensure I see clear water.

Thanks for ALL the support in figuring this out. My trusty hanger will stay in the camper. I have a filter but this is a used, but new to me camper, and my first one.

 

[Franktafl]

Happy dance!

Well at least that was the crud in your freshwater tank.....

Just years of whatever sediment was in city water settling to the bottom. Whatever it was is probably in all of ours too.
