Warranty? Can’t remove Air Admittance Valve

[FirstAscent]

Looking for some input here on my 2021 381M although this really applies to any model.

I’ve been wanting to replace my AAV in the main bathroom sink but when they assembled it at the factory they left no clearance to actually remove it. As you start to unthread it it goes up against the glued on counter top so the only way to remove it is to cut it off.

Typically this is any easy swap, unthread old valve, thread on new valve.

I told the dealer about this expecting them/GD to fix it before my warranty is up and they submitted my claim as I asked but did tell me they don’t think it would be fixed under warranty.
To be clear, I haven’t been told no yet but I want to gather info on this so I’m prepared as I fully expect them to fix this.

IMO it’s just bad quality control. Things happen and as long as things like this are taken care of then I’m ok but the dealer didn’t make me feel too good about it.

You can see in the photos it is directly touching the bottom side of the counter top as I start to unthread it.

Let me know what you guys think and also let me know how yours was installed from the factory, did you have plenty of clearance?

Just cut the dang thing off below the collar and glue another collar on and thread on the new AAV. I can't see how in the world you would want to take this to a dealer to get changed out.

Exactly. Might take 2 minutes and 2.99

When I replaced the one under my kitchen sink I had to disconnect the pipe from the P trap. I was then able to tilt the pipe out and replace the AAV.

If it hasn't failed I don't think it would be a warranty repair. And do you want your trailer sitting at the dealer for 5 weeks to change something you could have done?

[FirstAscent]

All valid points! And I’m comfortable repairing it myself too.

It’s gotta go back to the dealer anyway so I basically just made a list of all the items I do want them to fix. They are working out all the details and ordering all/any parts I would need BEFORE I drop it off. This way when I do drop it off it’ll only be there for a day or two.

Agree with the above. I cant see why the factory thought this was a good way to install it all....must have been built on a Friday with the backup quality guy on shift.

I just want to add that August 2021 I purchased a brand new Imagine xls 21bhe.

I have noticed that my gray water drains slow and then when done, the remaining water in the hose seems to be held in with a suction. PLEASE NOTE: we put nothing down the sink except clear soap water. All dishes are wiped clean before washing. So there is absolutely nothing to clog our tank.

So, it seemed like a venting problem. Checking admittance valve under bathroom sink, I reasoned that if I removed it I could see if that open vent would help with draining gray tank.

Alas, I found that my Admittance valve was NOT REMOVEABLE for the same reason mentioned above!

YES - I will cut it off and replace BUT....

BUT BUT BUT - Most people that I know could not do this and shouldn't have to. I check my kitchen valve and it is nearly impossible to even get at. With a mirror and flash light I was able to see that it too was right up to the counter top. I pray I never have to deal with that issue.

STILL - I have to find out about slow gray tank draining. Any ideas?

Thanks

I agree with you that we shouldn't have to cut a pipe to replace a part that is screwed on. We are also careful with goes in the tank. On ours, when I want to completely drain the grey, I refer to it as the never ending trickle. It will initially have a good amount of flow until it gets to near empty then the trickle never seem to end. We're lucky that we can dump at home so I just leave it open and go do something else. I think that it has to do with the placement and pipe angle. At least in our case.

Just curious and new owner. Why do you want to replace it? Is it defective? How did you know?

Thanks.
