Snaked the standpipe but it stops approx 2-4ft in and won't go any further. Im guessing it is a lint clog that is causing it to overflow whilst washing cloths. Read some other posts and compression fitting was mentioned here and there so I figured id try it.

Hi Neatooz...

Is there a PTRAP (u shaped fitting) in sight? If not, then the resistance you meet at ~2-4 feet in is the PTRAP and that will need to be negotiated to get into the drain line and snake the drain. The trick with negotiating PTRAPS is to continually push on the snake as the snake turns and eventually you should get past the PTRAP. Another issue arises, however, that once you get past the PTRAP the snake can go UP the vent as often as it will go DOWN the drain so that can complicate things abit more... ;)

If you have a flat roof with a laundry room vent pipe going out the roof you may want to consider snaking down through the roof vent.

Anyway, that's my thoughts with the information you provided. I would NOT recommend installing the compression fitting in this case, OK?

I don't know if there is a PTrap or anything down there. Its all blocked by sheet-rock. All I can see is the standpipe hole and the hot and cold nozzles that sit in the Safe-T-Drip pan.

Ill try again and use more force.

There is definitely a PTRAP as they are installed at every fixture... it's what keeps sewer gasses from entering the home. Let me know how you make out... ;)
