2014 Classic Anthem AAV replacement

[NowGo]

After reading several threads regarding the OEM Air Admittance Valves and their failure rate, I have determined I need to replace mine.

I have a 2014 Anthem 42DLQ.

There are 2 parts to this thread

Part One
I learned that the male threads where the existing AAVs are attached are 1 1/4". The new Studor valves are male 1 1/2"

After seeing the solutions others have had to come up with (couplers added to bushings, etc.) due to the lack of adapters (female 1 1/4 to female 1 1/2) at the likes of Home Depot, etc. I kept searching for a solution.

I have found adapters that I believe will work at Replacement Boat Parts (pic attached). I have ordered 3 of these adapters and they should be in next week. The 2 AAVs under the sinks are no issue at all, with easy access. Not so with the laundry cavity.

Part Two
I have created a procedure (PDF attached) that I plan to use when I replace the AAV in the laundry closet, unless someone has an easier/better method!

All of the posts I could find referred to removal of the washer and/or dryer, and not just accessing the AAV. Those were a big, big deal, and I do not have the appetite for that. Also, I could not find any posts where the DLQ model was addressed.

So... I created this procedure and sent it to Entegra for their feedback. Entegra replied that both service and production could not see any issue with my procedure working.

Now, as soon as I can work up the courage I plan to try to access the AAV using the method in my procedure.

If anyone has accessed their AAV valve in the laundry cavity please feel free to weigh in. I am not eager to use my procedure to access that area but I cannot think of another way to do it.

good find on the adapter, I had one book marked on ebay and it has been out of stock for a year or so, I also checked the Arylette link posted years ago for the 1 1/4 AAV and the link is dead ( i bought 3 a while back).

when I was at Entegra I went to all the surplus places and dug thru the bins looking for the 1 1/4,s non were found even the big totes around the back of the buildings.

I too looked everywhere for an adapter & finally gave up, so this is good news. I have one under the kitchen sink also. Haven't looked in the laundry. I will be watching your progress. Thank you for your determination.

My 2014 Anthem didn't have one in the laundry, it had the actual roof vent pipe. While I was in there I sealed the washer drain tighter in the pipe to prevent odor leak there.

Seems like my 13 worked with the Studor with the included adapter (from Home Depot) on my AAV's in the motorhome.

My Aspire 44b is set up like Rays’. Washer vented out to ceiling
IIRC, when I replaced mine under the sinks, the Studor came with an adaptor and was a simple plug and play.
As for the washer, plumbers putty around the discharge stack is all you need to keep gray tank smell out.

I sealed around the washer hose where it goes down into the discharge pipe. I used putty and tape to stop smell there as it can appear in that area to.

Update: The adapters arrived. I changed out the 2 washroom/vanity sink AAVs. The adapters worked great, I could not have put the Studors on without the adapters.

I am thinking I will indeed use some plumbers putty around the washer discharge hose where it enters the abs pipe. I may be able to do that through the side access door in the closet. Can’t hurt and may be where the grey tank smell comes from (when the bathroom fan is exhausting air more than 10% and no windows open). That would be a lot simpler than removing the wood trim (as I described in my procedure)

I just read that you are not to use plumber's putty on ABS or PVC.

So much for that idea.

I put a reducer on that got it close to washer hose size and just taped off the gap.

Just found this:

I remember some of the washing machines in the "Classic" year Entegra's had a drain hose too long so that it was pushed down into the P-Trap causing some of the gases from the gray tank to back up into the coach.

I used the putty that you buy a roll of RV Butyl seal tape on Amazon it works for a bunch of stuff. Even the pipe at washer
