We have some friends that just bought a used 2022 37k that’s different than our Seneca 37HJ. Is there only one black valve for both bathrooms in the 37k? Do they both empty with the pulls of the one black valve?
In My 2021 37K there is a valve for each of the black tanks. One is in the bay just in front of the rear wheels on the passenger side. The other is in 2nd bay behind the rear wheels on the passenger side.
