Leaking low point drain

[drchef]

We have a 2015 Cherokee 264L with two low point drains just forward of the outside shower on the slide side of the unit. The blue one has a shut off the white one does not and it drains constantly. What is this from and can or should we try to cap it? Thanks.

Are you using the trailer?

My lite is set up like that, both lines have a cap on them, could you have lost one?

Any low point drain I've ever seen are RED (hot) & BLUE (cold), never a white one. I'm wondering if you are calling the white drain a low point drain when it may be draining something else. I have no idea what it might be draining, unless perhaps something like the defrost function on your frig. Do you have any info in your owners manual (probably NOT) that might shed light on this white drain? If there is not a drain valve on the white tube, perhaps it's missing the "washer and cap" that fit on the end of the tube. That is a strong possibility if the white tube is threaded on the end.

Both of my low points are white below the liner, above that they are red and blue.

The FW tank drain and overflow are white as well.

Could it be the holding tank vent (overflow)?

Is there any kind of threaded connection on the end of the leaking white line? If there is, then I'd install a valve or a cap. If there isn't, then I'd agree that it's probably not a low point drain, but something else.

Mine does it also. It's the vent/overflow for the fresh tank. There is a write up on the forum somewhere for rerouting it so it won't siphon. Could be the issue.

A loop in the line will work also

Thanks! It seems to drain more on really warm days and we actually keep very little water in
the fresh water tank as we are always hooked up to city water. I'll look into this.

Do not kink it when you make the loop.

Low point drains are typically red and blue and side by side and capped. Fresh water drain should be opposite side of fill area and should have a valve on it.

You may think there is very little water in the F/W tank but hooked up to City water and a "Bad check valve in F/W pump allows water to Backflow into F/W Tank" and out the overflow/vent! Youroo!!

Not all overflows have valves. In fact, I would venture to guess that most do not. Lots of threads here about people adding the valve to stop siphoning.

OP said it drains MORE on hot days. Could it be condensate from the AC or refer?

A/C condensation comes off the roof, no idea about the fridge.

My money is here with youroo.

I have a Cherokee 274RKS. My two low point drains are just to the left of my door entrance (this is the only door on the trailer). One is red, one is blue, and they both have black caps that screw on to them. There is a label on the side of the trailer just above the drains that states "low point drain". On the other side between the two axles, there is a blue hose with a valve on it so you can open and close it. Next to it is a white hose with nothing on it, so it is open all the time. I assume that this blue hose is the fresh water tank drain, and the white one was a vent for it. I could be way wrong. Makes me curious now.

Put a little compressed air to it and listen....

[Dennise]

Two things.
1. If the valves are the pull up-pull down type, make sure they are FULL down (off).

2. You may need to flush any debris out of your valves. Fill your freshwater tank with clean water. Now cycle your drain valves fully up then full down .... about 5-sec up and 1-sec down each time. Do this for about 5 cycles and leave the valves fully down,

Do the same procedure if your valves rotate on and off instead of up and down.

Hope this helps. It worked for me.
