I need to install lift pump for utility tub to drain to sanitary.

So, after a whole lot of work in my basement, I found out now I need to do more.

My sump pump and ground water go to the same location, and then are pumped to the sanitary by the sump pump. This is how things have been at my house since I bought 15 yrs ago. Apparently that isn't correct, or allowed.
I need to put a lift pump for my utility sink to push that water from the sink, laundry out into the sanitary piping.
I have to separate the laundry from the sump. So I'll also have to go through the wall and then trench out to the ditch and run a pipe.

I did some searching, but I'm looking for people who have done this if you have any photos. Also any good reading for doing. I think it is fairly self explanatory, but now since my city is involved I feel like I'm trying to hit a moving target.

Probably easiest is to buy a packaged pump, like this one: https://www.amazon.com/Liberty-Pumps.../dp/B001DEOFLW

It's essentially a sump pump in a watertight box. Installs like a sump pump too, with a check valve on the outlet. Run the inlet to your utility drain, the outlet to a check valve and then to your sanitary, plug it in and you're good.

Thanks for that info, I finally got the pump.
Have you used this one before? You say it has a check valve on the output already?
I have a 1.5" male fitting, but it seems too small to fit the pump....(at least thats what she said).
Anyhow, I opened up the box last night to make a plan, but my fittings don't work in the pump.
Curious of the size I need to thread into the pump.

No you have to install a separate check valve on the output. Use the same type you would use with a regular sump pump. I like to use the clear ones with integral unions so it's easy to see if the check is clogged or blocked open by something.

The packaged pumps are available with both 1 1/2 and 2" inlet and outlet, so size depends on which brand/model you bought. Most common is 1 1/2. A schedule 40 male adapter should screw right in.

Ok...
I have a 1.5" check valve that I was trying to screw into it but it was too small.
I have the 404 which says 1.5", but maybe I need a reducer or something.
I'll get it, thanks for your help.

The Liberty 404 is definitely a 1.5" fitting.
