Sink not draining, brand new.

[Caligator]

Just install a single drain sink. Professionally installed by a licensed plumber. The sink is a Kurran single basin/drain and the drain is offset. At a low volume of water the sink drains fine but once you turn up the water flow volume, it starts to overflow and slowly drain. This is the first single drain sink we have had and the dishwasher drain line has not been hooked up yet. The plumber has put some duct tape over the hole in the drain pipe. Here are some pics.

You'd be surprised how often installing new stuff on old pipes exposes clogs that weren't apparent before. I'd imagine you just need the line snaked.

Embarrassing that a "professional" plumber would just tape over lines instead of putting caps on them, or finishing the job, though.

Well right other side of the wall of the kitchen is a sunroom with a potter's sink and the drain is using the same drain from the kitchen and no clogs. I was wondering if a single drain in the kitchen with a garbage disposal on it can build up since the p-trap may not allow air to release when water goes down. It drains at first and then it clog when the water volume is high.

Your disposal is blocking the view of the pipes behind it.

Meanwhile, if you used to have a double sink that drained well, it sounds like your new single sink is starved for venting.

With a double sink, the sink that is draining can get some extra venting air from the empty sink next to it.

You might benefit from adding an air admittance valve to your new drain.
