Toilet plumbing (sanitary) versus shower drain connected wrong?

[JMitch]

I am doing a minor renovation and I changed the pipes for the plumbing. When I spoke to a plumber who happened to be passing by, he said the work was done incorrectly.

The 3 inch pipe has a toilet above it. The 2 inch pipe comes from a shower.

This is in DC where 2012 ICC plumbing codes apply.

If this is incorrect, what changes are needed to make it ICC compliant? I'm thinking perhaps the 2" pipe should connect to the 3" (or maybe it's 4"?) vent stack in the rear corner.

The shower should have connected to the vent in the right corner. And the trap arm is limited to five feet from the vent.

You are also not permitted to have one of these "low heel" fittings for drainage:

They are thinking that solids are not given enough of a head start going the right way and could get into the drain line for the shower. In practice it probably works OK, but it would be flagged in the inspection.

Thanks - I appreciate the tips!

I've pulled out santees on their back below a toilet and it didn't work out well for the homeowner. I would never install one that way.
