Pulled the washer to replace the two AAVs. On my coach, a wall is very close to the washer cabinet, so a bit more difficult.
Refer to pic #1:
I took both lower doors off, removed the door catches on the middle shelf from both top and bottom. The top catches make it difficult to remove the top cabinet floor, the bottom latches can catch on the washer removal and install. At very bottom of washer is a carpeted retainer board. Take it out to pull washer drier forward and out. It has 3 screws under the top carpet, one middle and one each side about 3" from the edge. When I put the board back I used no screws - it is going to stay put just fine w/o screws.
Pic 2: Access to water valves. Mine did not want to turn at all, and I did not force it. I went outside and turned off the water at the manifold.
Pic 3: Removed floor of top cabinet. I had previously permanently removed the ceiling of the bottom cabinet - see no need for it.
Pic 4" I left water hoses and drain hose attached as they were long enough. I took off the drier vent hose from the washer side.
Pic 5: new AAVs installed - both serve washer drain system. One close to the loop the drain hose makes (forms a p trap) and one close to the actual small p trap. Two probably because other wise each p trap will syphon, plus more water volume in one shot from the washer than other locations.
The old AAVs had curling rubber seals as in pic from a previous post. While I had the drier out I cleaned the vent hose to outside, and the actual drier vent. On drier remove hard outer plastic ring and shine light down rubber vent boot. I used long needle nose pliers to pinch out some lint, and used vacumn with crevice tool while operating the drier for more air flow. Pulled a pretty good size lint ball out.
For this location I would use only the more expensive Studor AAVs because of the hassle of pulling the washer drier. Longer lasting solution.
