laundry room remodel

[Ricci]

We purchased a home built in 1963. When we took possesion we found basement(lower level in split level) waterproofing issues which caused us to tear out the walls in the laundry room. While I working on the room I wanted to lay it out in a manor to maximize space since its only about 5' x 9'. In one of the walls i tore out it has the main stack for the upstairs. Here is what I have so far. I think my vent connections are over kill and can simply be 3 way but I will let you guys tell me. The sink on the left is new and the water softner use to feed into the washer drain with no air check. I am trying to do everything right and just want some help becuase this is the most complicated job I have handled. I am unsure if I have the 4 vents on the left connecting properly. I am sticking with 1 1/2" on sinks and water softner and using 2" on the washer. All venting will be 1 1/2".

Thanks in advance

Here is what is in there now. It is all copper 1 1/2" on everything but the stack. The p trap is 2" from a recent remodel I assume. All connections are old 3 ways no tee/wye technology.

You can drain the water softener with the washer drain if there is an airgap before entering.

The sump would enter using a check valve. Not everywhere lets you pump ground water into a sewer system though.

Every trap needs a vent, somehow. Your drawing reverses some of the fitting directions.
Currently, on new work we use combo or wye fittings to vent if they are on their back. Santees on the vertical.

Terry thank you! That "sump" is my bad handwriting and is a sink in the other room. Which connections do I have reversed? This is all great feed back thank you very much

It is also probably hard to read my writing yet again but all the fittings on their back are combo tee-wye.
