Kitchen sink won’t drain

[Cannon915]

Hello everyone. We have a 2020 Alante 29s. Took it out for The first time. Everything’s great - except - the kitchen sink will not drain. This is the first time it’s been used. A little frustrating. The rest of the plumbing seems to drain fine. Any suggestions?

Did it drain at the dealer during the PDI? Are you sure the tank is empty?

If tank empty try running one of those plastic snakes down thru the p trap.

Check your drain vent. Mine is under the sink, but I have a 35S. If your vent is stuck closed, the sink will drain very slowly.
