Position of high loop adequate?

[Skinbabwe]

Recently had a new sink installed by a handyman. There were issues with his install (leaks, slow drain, smell, and the dishwasher backed up). Following some rework, he left the plumbing in this state, without the high loop. After continued issues (slow drain, smell, standing water in dishwasher), I installed the high loop as shown in the photo and the loop is 33" above the floor.

I also snaked the drain twice to remedy slow drains, water backing up in the sink and foul smells. During snaking, I can smell sewer gas release inside and outside the house. Though I can't visually confirm, I assume that the p-trap vents to the roof as there is a pipe outlet on the roof and I can smell the gasses during snaking outside the house.

I am wondering if the high loop is still not right - is the high loop drain considered on the p-trap as it sits below the p-trap outlet? Do I need to move it up so it is above the horizontal on the p-trap outlet?

I still get some foul odour and standing water in the dishwasher, especially after not running for a few days.

Thanks!

The high loop is fine. The trap is not, it is way to deep and likely the cause of the slow draining and smells. It is also glued together with no way to access the drain for cleaning. I would redo it all in tubular with the dishwasher draining into the horizontal arm from the other sink using a branch tailpiece with a directional baffle. Similar to this setup.

Thanks GR. I'll follow this design. Much appreciated.

Asking this just to learn.....in the OP's photo, the branches coming out of the front wall and side wall are, of course, currently in fixed locations, and he appears to have a single basin sink. What fitting could he use for the dishwasher discharge that would shorten the depth of the trap? From what I've read, the dishwasher discharge needs to be before the trap, so other than putting the discharge fitting on the branch coming out of the front wall, which I'm not sure is permissible, what fitting would work and allow the trap to be shortened without having to do a major relocation of the front wall branch or side wall branch?

No, it appears he has a double bowl sink. Do it like GReynolds929 said.

Confirmed double bowl sink behind the partition.
