I have a2022kw29,the kitchen sink is in the slide and both drain and water are slow, has anyone increased the size of drain and water lines to help with this problem?
Please be sure and have at least a 1- inch downward slope, to the drain pipe, if it is too level from the sink, to the drain , it will drain but very slow.
I also suggest that you remove the two large drawers under the cooktop and hope that you don’t find a situation like this where the kitchen sink drain line runs between the back wall of the slide and the bedroom floor toward the gray tank.
With the kitchen sink in the slide you have to have some sort of flexible drain hose, probably corrugated and not the typical hard pvc. Check the routing of that flexible hose and make sure it isn’t getting kinked or pinched while the slide is open.
FWIW, on my 2021 Axis Thor’s installers kinked and pinched the suction tubing from the fresh water tank and the outside shower hot water tubing. Both were easy to fix by rerouting.

Good luck

Our sink is in the slide I would check for kinks you could have a collapsed line. Unfortunately on ours the heater hose came loose and melted our line cause a nice little flood.
