Kitchen (galley) sinks drains REALLY slow.
We have only had our 2020 Sportcoach for less than a week. The galley (kitchen) sink drains REALLY slow. Washing the dishes will result in three of four inches of water in the sink. After twenty or thirty minutes it will finally drain (leaving scum in the sink. The shower and head sink drain fine. You can hear dribbling to the left of the sink, which is where the shower is located.
The sink is part of a slide out so I am guessing that there is a hose that connects the kitchen sink to the shower drain and it is pinched or something. Using a plunger does not speed or fix the issue.
Hopefully the dealer (we are not holding our breath for this) will contact us this week to schedule a return trip to fix all the items on the punch list. But I was hoping someone had an idea what was causing this and had an easy solution.
