How do you drain fresh water?
How can I drain my fresh water tank? They filled it up during PDI and I never boondock, so I don't ever use it so its just extra weight I'm hauling around. Suppose I could run sink and dump into grey tank and dump grey tank.. Just curious.. 369 bus

There should be a fresh water drain sticking down below the water tank. There's no need to run it into the sink and through the grey tank. Just open the fresh water tank drain valve and let it run onto the ground - it's just water.

DocP, I see no drain anywhere. I see the hot and cold low point drains down near the kitchen, those are the only drains I see anywhere.

Our fresh water fill is thru an inlet on the side and it is above our fresh water tank. Below that fill port, under the trailer, there is a water line extending down below the coroplast that has a valve on it to drain the fresh tank. I don't know how yours is oriented but you should have 2 drain lines, maybe blue/red, together for you hot/cold low point drains. Somewhere under your fresh water tank you should have an individual water line extending under the trailer with a valve.

Yea from what I can see, I see no drain at all. Nothing hanging down.. I see the gas line running from the propane.. I must be missing something.

My fresh water tank drain is behind the rear tires on the drivers side. I need to get on my knees to see it. One white valve near the fresh water tank overflow and vent hoses that should also be sticking out, but hard to see.
I’m not aware of any rv that does not have a fresh water tank drain. It’s there hidden somewhere. The water will go bad over time, it needs to be changed a couple times a year or it will start stinking. An occasional cap full (don’t glug it in) of bleach will help if needed

If you have that plastic stuff on the underside, it isn't inconceivable that it was installed OVER your fresh water tank drain(s). I have heard this can happen.

Best advice I can offer is look under the rig in the vicinity of the fresh water input port. The fresh tank will not be far from that, and the drain will be directly out of the tank.

My first TT had the drain valve out the side right underneath the water fill inlet.

Look behind your axles. It may be towards the middle. Hopefully not. It will most likely not be by the hot cold low point drains. If it is black, you may need a flashlight to see it.

If the surface you park on permits, I highly recommend getting a garage creeper for rolling around under your rig. There is a lot to see on these units and it makes regular inspections of the underbelly and suspension not only possible but even somewhat less than miserable. That fresh water drain is there somewhere. Good luck.

Success!!!
I found it, it was all the way at the back, near the rear bumper (first pic).
Drained Im guessing 50 gallons or so out.
But Im also wondering what these are.. and what they go to. Second Pic may be coming from rear ourside kitchen sink, but my other camper ran that into the grey tank.
The bottom one is on the main dump for the grey and black tank. It has the dump valves up front on the control panel, What is the little one on the smaller pipe, maybe a refrigerator drain or something? I dunno.

Ron, You might note almost everyone has a description of tow vehicle and trailer in their signature. This helps folks come along with more educated guesses to questions about a particular trailer. If you have a rear kitchen, your trailer may have a galley gray tank on top of the gray tank that serves other sinks in the trailer. Galley tanks typically have 1 1/2" pipes and not 3" as are more common on black and some main gray tanks.

A lot of owners think that the factory does things in a "strange and thoughtless way" but usually there's a reason why trailers are built the way they are. That reason is often not quite understood by a new owner. That is, until he gets into the situation where the "ah-ha moment" occurs and he realizes why that extra valve or that piece of metal is bent a certain way, but not used for anything is actually intended to do.....
Trust me when I say that Keystone wouldn't install a valve that costs them $3 in a place where it's not needed. They are far more "cost efficient' than that.
Before you start removing things that "don't seem to make sense" be sure that there's not a "intended purpose that you don't fully understand the factory's rationale"......
That doesn't mean there isn't a mistake in installation and something is installed incorrectly. That does happen, owners think far too frequently, but the factory thinks it's within their "failure rate" (according to the "bean counters")

My Cougar 30RLI had a drain right under the fresh tank with a valve on it.

Having owned a Cougar until this year I thought I was fortunate to be able to crawl under the trailer to open the fresh drain valve. Well, I bought a competitor's model and there is a pull handle attached to a rear leveling jack that opens the fresh drain. No crawling under the trailer. How novel...
