What do you mean by running trap? Is that the dip in the 4 inch pipe before it goes into the floor?

The 4 inch that goes into the wall in the third picture just goes to a vent in the side of the house? what is the purpose of this? Is it a venting system for the pipe?

thanks

The u-bend in the 4" cast is your house trap and the 4" line next to it that goes through the wall is the trap vent. The connection of the washing machine hose is someones idea of how to tie it in which is competely wrong. You need to install a trap and vent on that line. I don't see what you have pictured as a DIYer's first plumbing job, it looks over the head of most newbies. I would either call a professional plumber or take your time and read up on the plumbing code for your area.

What is the purpose of a trap? And why is it dangerous to not have one on the washer drain pipe? And does the whole house trap that is 2 feet away, cover the need for a trap on the washer line?

thanks

Ok, I found out that a trap is used to prevent dangerous sewer gases from entering the home. The water that is trapped acts as seal to prevent the gases from getting through.

So, as the above poster stated, is the trap that is in the 4 inch section enough, being it is so close to the washer and sink drains?

NO i did notice the running trap and yes i know it protects the house from city sewer
but "DO'ES" not protect from gasses in house waste lines,
per plumbing and health codes,

Hey Mikey...Wow, lots of hysteria. Normally there is a trap on the washer drain and the hose from the washer just sits in an open pipe that drops into the trap and yours has been improvised with a hose clamp to prevent the hose from coming lose and will also prevent gases from escaping....it is not what is normally done but when your house was built a lot of areas did not enforce plumbing code. It looks like the pipe going up off the wye after the washer clamp is probably a vent. It is still safe at this point and I was trying to get you a sink without cutting everything out.... because then you will be in over your head. Testing the floor drain with a bucket of water is a very good idea before you decide to use it...as it may go nowhere or simply be stopped up.

Incidentally, I did notice there was no trap on the washer drain and I would insist on installing one if you were to cut the wye out in order to add the sink (which would also have its own trap) and loop a vent pipe back into the small pipe going up as it appears to be galvanized pipe and would be easier to cut.. but you say it is too low, but I think you mean too high.
The running trap is there to prevent gases but if everything else in the house is trapped and vented properly it is a redundancy and not needed. But there is no need to cut it out and recreate the wheel the way it would be done today.

I have dumped plenty of buckets of water down there, and have not noticed any of it coming back.

Maybe not in Texas but a whole house trap is still required in many locations. He needs to have a trap on the washer discharge in any case. The last thing you would want to be in the area of an open frame motor is methane gas from the drain piping. I think he needs to call in a pro because there is no easy solution to adding a sink drain to the current set up.

It is true we don't have running traps in Texas and for the most part no basements either. In order to install a trap on the washer drain he would have to cut out the wye (blue and white 4 x 2) and the 4" 90 below it and pipe in the sink and washer drain at that point. He wanted to add a sink and is going to drain it to the floor drain (think of it as a trap primer for the floor drain...another protection) and leave everything else as is. Not perfect or attractive, but functional. To tell him he needs fancy pumps or that he is putting his family in danger and his house could explode because he doesn't have a trap on the washer drain is extreme. His house has been there since the 50's and has probably always been like that.
