Chuck, my dealer told me that I had to order the entire black water flush assembly to get the exterior fill connector (which is what I needed at the time), and the brass vacuum breaker came as part of the entire assembly, to the tune of about $80 as I recall. I was also told that only an Airstream dealer could get this part.

Of course, when I received the part, I located the mfg. here from the paperwork enclosed:

Home Page

The two photos below show the schematic with mfg. name, and the brass vacuum breaker as a separate part, at least to these eyes, with its mfg. name clear on the top.

Maybe you can get a brass vacuum breaker on its own from a plumbing supply store? It sure looks like a standard item IMO.

Good luck!

Peter

PS -- When I have time to remove the rear dinette seat, this will open up clear access to the plumbing space under the lavatory counter in my FC20, and I intend to swap in the brass VB.

Peter - Thanks for going to the trouble of sending the information. I'm now headed to the McMaster Carr, Grainger, and a few plumbing websites. This vacuum breaker is definitely different from the cheap looking clear plastic one I received from Out of Doors Mart.

Interesting Lakeview RV Supply, resource listed on the instructions for your brass valve, is also the supplier of the clear plastic device. Looks like the brass valve itself is sourced by Cash Acme in Taiwan from reading the top of the valve.

Hopefully the brass valve will prove more durable than the plastic one.

Happy to help. Note that the spec sheet says the VB is 1/2" IPS:

https://en.wikipedia.org/wiki/Iron_pipe_size

so hopefully you can swap in something easily, even maybe an identical part.

Curious what kind of access you have to this space. Do you have to do something as crazy as moving half of the dinette seating as a unit?

My VB is buried about as deep as you can get in a 20' trailer and still be inside!

Good luck.

PS -- here ya go:

http://www.cashacme.com/product/v-10...acuum-breaker/

The part number is identical V-101. The geometry compared to the plastic one may be different, but hopefully where the water makes a 90 degree bend (inside the unit) will be the same, so that the two female connections are in the same places. The photo in Post No. 2 suggests this may be a swap-out IMO, but you may need some short 1/2" brass nipples etc. to make up for the way the plastic sticks out on the left in that photo.

I have a 27FB. The valve is located behind a panel on the side of the trailer inside the main closet. All I had to do is remove everything from the closet, unscrew 10 screws, lift out the panel and the valve appeared on the wall. Removing it was simple.

Looking at the photo of the diagram for the assembly with the brass vacuum valve I'll also have to use a check valve. Any specs on the check valve used in conjunction with the brass vacuum valve?

Agree on the the need for some connectors. The plastic valve connectors are 3/4" and male. The brass are female.

Too easy a location!



Will check parts that came with VB later. OTRA now.

Sure enough the box of parts for the entire assembly from Lakeview RV Supply (link in Post #16) included a 2" gray plastic check valve, with 1/2" male threads on each end, so it looks like we are on our own to make the new brass vacuum breaker fit inline with the rest of the pipes here.

Looking at the photo in Post #2, this will mean replacing the elbow on the left, adding a check valve inline horizontally, and then the vacuum breaker on the right (above the vertical run back down to the actual backwash spray head mounted in the sidewall of the black water tank).

There is enough play in the two vertical pipes that it should be fairly easy to get some combination of stock brass/plastic parts to work, but my plumbing knowledge is limited so I won't guess about part names.

Plus I have never dealt with PEX lines and fittings . . .

Good luck!

Just wondering if you have tackled this project yet? I am thinking of trying the brass vacuum breaker soon. Thanks.

Due to some personal timing issues I decided just to install the clear plastic replacement valve Out of Doors Mart sent. I needed to get the trailer winterized and put into storage quickly so I didn't a couple of days to source parts and put what appears to be a better solution in place. I've saved all of this material for when the plastic valve requires replacement in 3 or 4 years.

Thanks for your help. If there is a replacement in the future I'll know what to buy and put in place.
