Not you again. Unthread the 1/2 quick connect hose adapter from the ball valve, thread a 1/2nipple into the ball valve, thread a 1x 1/2 bushing on that, thread the irrigation valve on the 1x1/2 bushing, thread a 1x1/2 bushing in the outlet of the irrigation valve then thread the 1/2 quick...

That drain looks deep enough to accomplish that. It can tie in less than 45 degrees vertically.

The whole group must be on the same elevation. Look at my drawing again.

That's not your problem. Call them back.

Find a happy medium for the height of both drain outlets. If they are both lavatories they should be the same heights...

The lav drains should have been installed with a double sweep. The lower drain is breaking the vent.

Also, I don't trust anyone anymore that say their a plumber. A lot of areas don't even require a license, you should ask them if they have one. One little mistake will cost you big time. Alot of people think anyone can do plumbing.

Draw a sketch of what you're doing and then you will get the correct answers.

By the way you have to be certified to work on it anyway. Just call a plumber that is certified to fix and test it.
