Two water drains?

I have a new 23D FC that has the white plastic fresh water drain behind the tires. It also has a brass fitting about a foot away. This one sticks out quite a bit and is the lowest point for ground clearance.

Is the brass fitting a second tank drain? The low point water drains are near the rear bumper accessible from inside the storage area. The manual addresses both the white plastic and low point drains but says nothing about the brass one.

Could this be removed or rerouted for more ground clearance?

Welcome..
Pictures 3-1!!! Pictures!

The brass may be the tank plug. That can be removed to drain all water. But usually any water left in the tank after draining with the white valve behind tires, won't expand enough to damage.. And you can you don't have to worry about rodents or bugs getting into the bigger plug hole during tow or storage.

Low point will be where water drains out of plumbing fresh water lines.. Don't forget your Water heater or under sink filter. Also, antifreeze in the P traps!!!

No, not likely you can "relocate" the tank plug.

Pictured above are the two drains. Does anyone know the purpose for the brass on the left? Can it be removed?

Did you purchase this AS 'new'?

That appears to be the drain for the Fresh water tank. ... but, so is the white valve to the right... there is usually a 'plug' in the bottom of the freshwater tank... and if someone replaced, then that 'arrangement' would make some sense.

So if you do not see another 'plug' in the bottom, then this might be a 'low point drain'.

When you open the valve, with no water attached and no pressure on the system, does any water come out? Does it come out faster if you open one of the valves in a sink?

In my personal opinion, a brass fitting like this would be inconsistent with all the other plumbing fittings on a new Flying Cloud (mine is a 2014 20-footer). It looks more like a propane fitting.The red handle is consistent with this possibility. Is the left end threaded and curved/convex, as if to accept the flared end of an LP compression fitting with a nut on the end to complete the connection? Can you get a better photo of the left end?

A number of questions come to mind. Does your owner's manual say anything about this? Was your coach perhaps prepped at the factory or dealer for an optional propane appliance of some kind? Does your paperwork list any options which might apply? Please send your photo to the dealer and ask them what's up.

It is my understanding that the metal pan being shown is actually a protective box around ( and separate from ) the actual plastic fresh water tank. Mine looks very similar FWIW, but without the brass fitting. If so, the drain plug at the bottom of the fresh water tank, mentioned by cwf, is probably buried out of view, again in my opinion. Also these drain plugs are more nearly flush-mounted I believe.

Inside the coach above this area, is there some corresponding brass fitting, perhaps buried under your toilet or lavatory? I think your bathroom is the same as mine? See floor plans here:

2016 Airstream Flying Cloud Floorplans & Specs | Airstream

If you remove the aluminum cover plate to the right of the toilet, on the raised floor box supporting the toilet, you can see what is inside this space. You will need a flashlight, and it helps to take some photos looking up also, with the flash on, in order to see what is under the lav counter. [OT comment -- You may need this information for other reasons later on down the road, as my vacuum breaker for the water feed for the black water flush system leaked IMO, as it is the old style plastic unit. If yours is all brass, you may be OK. -- end OT comment]

Curious to know what your brass fitting is, as we all try to figure out our new units. Please keep us informed about what you learn from the steps suggested above, as well as in the comments by others during the day today.

Thanks and good luck!

Peter

PS -- edit -- is there anything like this brass fitting under your rear corner bed, as I believe you have one or two exterior access doors to this space?

PS2 -- edit window expired -- Any chance the brass fitting is for a BBQ to be used outside the aft end of the coach? Any mention of this possibility in the manual, or in your delivery paperwork list of options? If you open the red handle, does propane come out (propane tanks on)?

Hum.... Looks like a gas fitting but why would that be there? It is rather low.

Did you open it to see what came out? Gas or water?

In our 23 Safari, there is an access under the wardrobe closet near the water pump but deeper, where you can see the front low point drains and fill pipe going to the FW tank. There are no gas lines there.

Who would put a gas or water connection underneath the trailer in such an awkward spot.

I can only think it is a drain for the FW tank enclosure, but that shouldn't have water in it.

I agree, it is too low and just something to shear off from road debris.

That brass thing looks like a propane valve, and if so, I would not want it to be the lowest point on the trailer.

The white plastic valve appears to be the fresh water tank drain. The brass valve appears to be one of the water line low point drains. The brass valve doesn't look like an original valve. Someone probably replaced a damaged low point drain valve with the lever handle ball valve shown in picture.

Ditto to the recent comments, and one further thought if it turns out to be a propane valve: no propane lines should go into inaccessible spaces such as the one above the sheet metal pan which also houses the white plastic fresh water drain.

Hopefully your dealer can explain this if the brass valve is not OEM or a listed option. Do the pan head screws holding on the sheet metal protective pan (under the fresh water tank) look like they have been removed and re-installed after factory assembly?

Plenty of breakfast comments for you to digest on the West Coast, 111 !!!

With water in your fresh water tank, open the valve and turn on your 12v water pump. My International Sig has two similar valves side by side in the same position that is for pumping the 12v pump system dry.

Is your second valve also brass, and maybe intended for an air fitting with pressure supplied to bleed the system dry? You'd think the owner's manual would cover this . . .
