I have a new home being built.
The drainage pipes for the Kitchen Sink were placed about 12-14" off from what the plans showed in the slab.
The plumbing contractor used a 90 coming out of the slab (had to stay below the bottom of the island, so it is quick 90), attached to a 12-14" straight pvc pipe, and used another 90, attached the 90 to a short straight, and then attached to the kitchen faucet connections.
My concern is that the kitchen sink and garbage disposal drainage will have to go through 2 - 90degree connections before going into the slab.
Does anyone know if this meets any form of code or if they have an opinion that this is not recommended or this is normal practice for these types of issues?
Any info would be appreciated.

Be prepared to have a chronic problem with stoppages. It takes a certain mindset to use PVC ells (short radius) fittings when a decent plumber would realize a 2" CI Iron sweep would allow for better drainage

Also when coming out of the slab the installer could have used sanitary tee in lieu of the ell with clean out plug on the top of the tee (called the run) or possibly after the ell short a small piece of PVC and a TEE with a CO on the Bull to allow for easier rodding (snaking of the drain)
