is this acceptable?
If not let me know what's wrong and/or what could be or should be improved.
It goes out through foundation to septic.
Original piping was a copper dwv, galvanized copper?
Let me know if you can tell, house was built in the 1960's I think, or maybe early 1970's.

    Seen a lot worse... other than being not really happy about the venting of what I assume is a wahsing machine outlet standpipe (it's wet vented, and I'm not sure just where and how) I'd be OK with it.

    yeah 3rd pic down shows where the washing machine drain empties to.
    Is there any better [looking] way that could be done for dealing with the washing machine drain?

        Acceptable and somewhat typical with an A plus for the tub / shower trap & its correctly plumbed vent; I discover dry horizontal venting at tub drains frequently during bathroom remodels and the vent is usually  plugged.
          We always prefer verticle to horizontal waste connections via a wye, but there are millions of ty's on their back & sides accepting waste; this helps Plumbers stay busy.
           Never used any side outlet ( inlet ) 90's, so not a fan of those. 
           The trap & standpipe could use an aav even though as Jamie Hall points out - that trap will almost always see atmospheric pressure.

    i prefer the washing machine in that situation be run to a pump. 
    The drain hose should be just above max fill in case of solenoid failure.

    Looks like they had a bunch of short pieces of pipe and glued together with couplings Washer stand pipe could be taller but if it works, let er rip.

    The closet 90 with the side inlet (second pic) should only be used to accept a wet vent below a toilet. But if there’re no issues, I’d leave it alone.
    There're a lot of things that have been done to plumbing in old houses that don’t meet code, but seem to function okay.

    In my area, UPC codes, that would not pass at all. I assume the larger copper pipe going in to the main is the toilet, in which case it is not vented properly. Also the washing machine is not vented properly. That side outlet 90 is illegal in the UPC code.
    But, that being said, I bet it all performs just fine.

    Will it work yep, Did a pro do it Nope

    Laundry isn’t vented, toilets aren’t vented, side drain 90- never meant to be a “drain”. No hangers.

    Of all the code violations  that wash machine is probably the worse. Not vented and way too high

    At least the top of the pipe is above the water level in the washing machine. Always look for the positive.

    with the pipe at about 4 feet above the floor going through the foundation out to the septic, how can a washing maching p trap drain be located at 6 - 18 " above the floor?

    I don't remember how that was installed there 30+ years ago when it was done at house build time,
    and from what I was told "a pro" i.e. licensed plumber did that piping when the new tub was installed just above it, apparently the definition of pro is subjective. While I don't remember how it was plumbed when I was a kid before it was changed I do remember there being a washing machine in that exact location.

    Do I need to remove the washing machine and start going to the laundromat?

    How can/should the washing machine drain be plumbed given the layout in the pic? Someone said they prefer washing machine be run to a pump... is there a way to do it without putting in a pump up?
