UPDATE thanks all for the comments, just a few clarifications and updates:

• all electrical work is work-in-progress, we’re finishing it up tomorrow, it’s still an active worksite. The old outlet and old bx wiring is being removed, we’ll only have the newer wiring (and of course all outletd will be in their gangboxes and covers will be on)

• the dryer vent will be changed and installed without sag when we finalize

• the 4" abs drain connects to the old one with a rubber fernco gasket, those do require hose clamps and they’re up to code (though the top clamp could be straightened!)

• the water lines are pex, they’re all good

• we don’t have a choice but to push the water up with the washer pump - the drain evacuates to the city sewer around hip level in that basement

The worries for me are really the 90° out of the sump pump and the other 90° into the drain column, shouldn’t that be a downward Y? And the double S p-trap, is it creating some risk?

For the record he also connected the sump pump pipe like this, with a 90° - shouldn’t it be a downward Y instead?
