Very Slow Drains

[dbaur]

We have a 2016 Classic and the shower and bathroom sink drain very slow. We have tried baking soda, white vinegar and "Unique" drain cleaner. Nothing seems to work. Will appreciate any suggestions.

Make sure the vent pipe is not clogged with a bird nest or other obstruction. If the air can't leave the grey tank, the water can't get in.

I think both of those drains use a trapless system. I found a couple of them that had the end of the "trapless" part stuck almost closed. I opened it up, and the drains worked much better.

Hmm, not familiar with these and have had no problem so far, but thank you for the info!
