We have a 1999 Xplorer 230XLW and noticed that the shower will not drain (very very slowly) if I also use the kitchen sink at the same time. I would guess that water going down the kitchen sink will restrict the shower drain from flowing.
At first I thought there was a clog, so I used the baking soda/vinegar treatment and poured down hot water. Needless to say this didn't solve the problem
Does this happen to your RV?
Thanks,
Chuck
