Why would a brand new BC 20X black tank flush clog?

We just got our new shiny BC 20X. It's one beautiful trailer. I might post a separate review on all the pros and some nit pick cons. There are so many things that Airstream has done really well.

I do have one minor glitch - the black tank flush is not letting water inside the tank. I tried everything (increased water pressure; kept the water knob open for several mins; towed with full tank to clear the inside nozzles, etc. but nothing worked). I don't want to blow air, because I don't know how delicate the inside nozzles are structured. The unit is an out of state delivery. I should have checked this feature when I got the delivery. We checked everything except this feature. I'm not too worried because there is warranty.

I can understand if this happened on older units. The inside nozzles might get blocked with periodic build ups. But why would this happen in a new unit delivered directly from factory few days ago? How did the quality checks miss this issue? Black tank flush system is a new feature added in BC 20 models. So it's a bit disappointing to see this feature not working.

Any suggestions I could try before I loop the service crew and invoke warranty? Appreciate any pointers. Thanks!

Why is difficult to answer. Installed wrong? Faulty part?

I would just let it be handled under warranty. Maybe wait a bit to see if anything else comes up so you can get everything handled at one time.

Sorry for your troubles. Good research IMO.

Air pressure at 30 PSI should not hurt anything IMO, and you should be able to hear the air escaping from the spray nozzles on the top of the black water tank. [with the trailer and surroundings very quiet -- which includes the compressor being off]

Guessing a plumbing error, or a defective anti-siphon vacuum-breaker valve?

"Quality checks?" . . . . . . see here . . . good company.

Ditto to last comment to let a dealer check under warranty after further investigation per above.

Good luck.

We just got a BC20X in January and the SAME thing happened with ours. It's currently at the dealer waiting on warranty/part. They said the black flush valve was "faulty".

Thank you for that report, and welcome to the forum. When you get the details of the repair, and the parts removed/installed, please update us. Our new 2014 FC20 came with a defective valve, and the dealer sent us a new brass version, because we were not able to get back there for a warranty repair. The new brass valve is sitting on a shelf above the bed, because this part is in a hard-to-reach location.

If there is a 2021 Basecamp 20X fleet-wide problem, it would be good to let everyone here know IMO.

Thanks.

Per the recent Post #6, is this a 2021 BC20X fleet-wide problem?

Thanks.

Dealer confirmed the valve was faulty. They didn't say it was installed wrong or backwards, just "faulty". They are replacing now. They also said the winterization kit was sucking antifreeze into the fresh water tank and not through the pipes. Yikes! They are placing that as well.

Easy fix. Drive side cabinet, behind bathroom, open the door, take out 4 screws (covered in white). Remove back panel of cabinet. Just over the wheel well is an anti-siphon valve that protects the black tank line. They have also added a check valve, it is a grey 2" 1/2" part coming off the right side of the anti-siphon valve. This check valve is most likely backward. Mine was. Unscrew the bottom of the anti-siphon and check valve, unscrew check valve. Flip so arrow goes the way the water should flow, into tank.... re-install.

Thanks for keeping us posted. I'm glad it's getting fixed, along with the winterization kit.

Wow! Thanks so much for the tips. I'll try this out tomorrow. I hope it's the same issue with my unit as well. By any chance, do you have a picture of the correctly installed valve? Appreciate your help. Thanks!

Thank you very much for the post and replies. Found it last night when doing a pre-first trip trial of the various systems and realized the inlet would not add water to the black tank. Our trip will start with a detour to our dealer to flip the valve. I was not confident after opening the panel per Mtstarr1's instructions that I'd get it right without assistance from the service folks but at least now I know exactly what to tell them to do! I will also have them show me where it is and what's what behind the panel.

photos of check valve repair

Okay, so I went from not knowing we had a problem with the black tank inlet until last night and not even knowing what a check valve was, to replacing it this afternoon myself without having to see the dealer. Here are some photos for anyone considering doing it yourself.

It's the gray plastic piece in the upper left of the close up photo. It was installed with the arrow facing the wrong way. I unscrewed both ends, flipped it, added some plumber's tape and screwed it back in. That's it. This is the panel immediately to the left of the bathroom, lowest level. Good luck and thank you to all who posted here!

Thanks for sharing the pictures. Did you replace it or just flipped the direction of the valve? If you replaced it, did you order the part from the dealership or picked from a local store?
