I am planning on changing my washing machine from draining into my laundry sink into its own stand pipe. My laundry sink did not have a vent but wet venting up through the kitchen sink drain. I plan on adding 2 AAV's to take care of the venting for both the sink and washer drain. Does this make sense? Is the 4x4x3 wye correct on the kitchen sink drain? Are the 2 4x4x2 san-t's correct for each fixture? I assume the horizontal fitting to connect the AAV's would have to be a combo wye + 1/8 on its back facing the stack.

Did you know some Redwood Pipe is still in service today.
Pumped? As in pumped out from the washer? If so then what?
If an AAV is not allowed on the washer then a vent would have to be tied in above the kitchen sink. Check your local code!
