Can't figure out how to drain fresh water tank

[dedmiston]

I need to drain my fresh water tank. The monitor says the tank is full and I know that I didn't fill it. Before we take our first dry camp trip I need to drain the tank and fill it myself to be sure.

I've had mixed info from the folks at Crossroads. By email they've told me that yes, there should be a large fresh water dump handle under the belly. But there isn't.

I spoke with another gent yesterday who says there isn't a dump valve. He said I just need to use the low point valve.

Since I live in So Cal I've never winterized any of our RVs before, so I'm not to clear on the whole low point valve thing. I understand in principle, I think, but I've never done it before.

I fiddled with the blue lever in this photo. I didn't want to be too forceful though. It would easily turn a quarter turn from 6 o'clock to 9 o'clock and then stop. I couldn't get it to pull out.

I'm pretty sure that's the right valve though. I opened the blue low point valve next to the red one and only got a few gallons out. I assume that only drained all the plumbing lines and didn't have anything to do with the fresh tank.

I can't figure out where I'm going wrong.

I don't anything about your rig, but every one I have seen, or been around has a small pex tube with a cap on it sticking thru the membrane on the bottom, right under the fresh water tank.

X2. Look for the white cap/fitting sticking out below. It is similar to low point drain.

Depending on conditions, moisture/humidity may affect sensors. Mine has shown a full tank even though it is empty.

I wonder if it's covered by the belly blanketing?

The only things I see poking through that blanket are the sewer dump line and two small blue breather lines back by the axles.

I would think they would have the drain line sticking thru the membrane.
Do you know what the (two small blue breather lines back by the axles) are for?
Are they the low point drains?

I can't tell. With that belly sealed up, everything is black-box.

[Lloyd]

The belly on mine is sealed up also, but the drain line is visible coming thru that black membrane. Right under the fresh water tank.

One of the guys from Crossroads just emailed me back and said to definitely use that low point drain handle in the photo. He didn't say whether to pull or twist. I'll give it another try. I hate forcing something like that when I don't know how it works.

[Lloyd]

I don't understand how a low point drain handle can/will drain the tank.

Look close to the frame of the rv. Sometimes the drain is hidden behind the frame. The low point drain doesn't make sense to me, just like Lloyd said.

[travelin texans]

The blue valve that says low point has to be it, there should be 2 low point drains hot & cold underneath somewhere.

low point is only for the actual hot and cold pipes. the fresh tank will have its own drain under somewhere. look in the spots you would not think of. maybe behind the wheels? gotta be hidden somewhere.

Mystery solved. The dealer removed the belly cover and found that Crossroads hadn't installed a drain. The line coming from the tank was capped and covered up.

The dealer is haggling with Crossroads to resolve it.

Firdt off ,that simple screw up should not have left the factory ...If they actually ever figure how to add a quality inspection station,...
Also should have been caught at the dealers ,as that should be shown on the pdi.
