Bought an old 45 year house. Had new washer machine and when it drains I can hear it at my kitchen sink. But the problem is that the water starts over flowing out the washer drain pipe so I went and extended the 2 foot pipe to nearly four feet. Worked great for 3 weeks then started to overflow again. So then I figures to cover both sinks completely with plunger while completely duct tapping the washer drainage line to force down the water at high speed, but then black water force it's way up both sinks and smell like hard iron and sewaGe but not sewage at all, make sense? What kind of backup do I have. I'm on city sewage no septic. Help me please !!!!!
