Hi All,I'm new to full timing. I've had my TT about 6 wks.I noticed this hose (see pic) had a slow drip. No mention of it in the manual and I'm on city water. (Fresh water tank is empty)About a week ago it became a steady stream. Its fresh water. I disconnect ed the water and left for a biz trip. Upon return it's OK with a slow drip again.Trailer is a 2012 Crossroads Zinger 27RL. The house is a LONG way from the hot water heater and the water pump which is off.This trailer has 2 water inputs - 1x for fresh and 1x city water. 2nd question if you're still reading, is what adapter can I get to fill the fresh tank from a regular (drinkable cert) water hose?Many thanks in advance.You should be able to view the pics here: https://photos.app.goo.gl/I25iFW3RoGDXUvzI3Chris.

Fresh water port fill....Valterra Model (Camco makes one...its yellow)Attach to your hose, stick it down into gravity fill port and turn on water (caution ---the tube on the Camco came off and went down my fill line) As for that ONE blue drain line ?Could be fresh water tank drainCould be Low Point Drain but usually there are TWO (one for cold and one for hot water lines)

This should work to fill your Fresh Water Tank with a water hose,second picture will show how.Click Here

I fill my fresh water tank with one of those brass hose nozzles you turn to get a spray or stream of water. I push it in and it stays.

Are you talking about what looks like a hanging blue pipe? Pic is deceiving as it looks like big pipe rather than hose (maybe my computer?) Looks too big to be low point drain valve - maybe prior owner McGyver'd alternative drain to gray/blackwater tank? Collect the drip in a cup and give it the "smell test" - should help determine whether you have FW issue or something else.

Not sure what the blue hose in your pic is. I don't think it's a low point drain, since there doesn't appear to be a valve on it. Looks like it has a threaded hose connection end. My initial reaction was a black tank flush connection.Mike

On my TT, the commercial RV fill nozzle was too short and water would back out the port. I cut one end off a washing machine supply hose and it works very well. It also has a secure attachment so you dont have to worry about dropping the hose in the tank.

I cut off one end of an old fresh water hose, longer than the commercial kind, also cheaper.

Thanks all. I'm going to try and find a cap for it.

The hose is quite small, smaller than a garden hose. Possibly 1/2 in.

I'm also going to toss some water in the fresh water tank and see if it leaks out right away. My gut feel is that it will, and that this is for draining the freshwater tank.

Saw a pic on another site of a similar hose with a cap. It was for freshwater drain. So, I suspect you (and those who said that) are correct.. and it's just missing the cap.

If your check valve in the pump has failed as previously mentioned as a possibility and you cap the blue line the tank will fill up over a couple days or more and begin to flow out through the tank vent at the tank fill cap and run down the side of the trailer. As long as it is just a trickle you are probably okay. If it stops trickling and continues the fill the tank then you may rupture your tank. The previous owner may have known the fresh water was leaking back through the tank and left the cap off so the tank wouldn't fill. You may need to repair or replace the pump if it is back filling the tank.

My money is on that. My 2014 Denali has no valves on the end of the drains (my '08 Jayco had valves), just caps, and the hoses look like yours. I bought PVC ball valves at Lowes to put on mine.

That blue pex pipe looks to be a gender changer, male-male instead of the female fitting it's attached to. It may have been used to connect a garden hose to drain the fresh water system or as an auxiliary outside water supply.

Hey Guys,

Well the filler tube for my fresh water tank showed up and as many of you guessed, I was able to confirm that it IS a drain for the fresh water tank.

The second water was put in, it came out. So, I ordered a Pex valve for it which should be here any day.

As for why it's dripping, I opened up my plumbing cabinet and there is some sort of cross over in the system and that seems to be how water is making its way into the fresh water tank.

I'm to sure if it was designed this way, or if the previous owner decided to plumb the pump into the City water feed.

Thanks for the help!!
