Brand new drain pipes, but my sink drains slower than paint dries. What should I do?
We renovated our kitchen and my husband installed a double sink, a new garbage disposal, a diswasher, and the drain pipes that remove all that waste water to the wall where the old pipes now begin. Why are we experiencing this super slow drainage? The drains worked with no problems before, so I don’t believe I have clogged pipes.

have him disassemble the drains to inspect, and re-assemble. there has to be traps for each basin. you should not need to consider “vents”, as none were removed.
something doesn’t sound right.
one way to troubleshoot this kind of problem is to disconnect the new pipes from the old. Then pour water down the old pipe even if you have to use a hose to do it. If a few gallons drain just fine then you know it is in the new pipes.
If not you need to look at the old pipes. As somebody else mentioned before it almost sounds like a venting issue.
You need to install a vent pipe at least 2″ pipe. When you changed the plumbing you created a siphoning effect in the drain line much like the water in a p trap. When we redid our plumbing I had a plumber come to give me advice and that was the first thing he told me was I needed another vent pipe even though everthing was close.
