Washing machine drain- skip the sink?

I have a washing machine that drains into a utility sink. The sink is always a problem, and Id like to get rid of it. Can I just run a pipe up the wall and attach the washing machine hose to it or do I need more parts? If so what do I need?

Hard to say as you did not give much info.

The pipe has to have a trap and be hooked into the plumbing.
So my guess is yes you will need more parts.

Pretty hard to tell you what you need when we cant see what you've got.

A washing machine must be hooked up to 2" pipe. If you dont have 2" pipe, that's a problem right there.

So far very helpful!

Since the washing machine was draining into the sink, Ill venture a guess that this setup circumvents the 2 drain requirement... but I want to fix this properly. My guess is the sink uses a bathroom drain so it is way too small. Since the washing machine is directly over the 4 PVC and I have access from underneath very easily, its probably a little more work than I thought but it would be worth it- so I just need to add a 2 drain with a P-trap into the 4, right?

It's not quite that easy. Yes.... you may have a 4" drain line below the floor but if that is a wet line.... not a vent.... you'll need to tap in and then add a vent line.

Does the sink have a vent line? You may be able to use that vent line for new drain.
