Pipe clogged - weird going down
Hi everybody! It's a 1 story home, no cellar, old iron pipes. There was a hole with a leak,in a pipe in the outside wall, which I patched and it's not leaking anymore (opened the outside wall and just patched the hole. this only leaked when the washing machine ( not a new one) was pumping out the water. After the hole was closed, the water comes back up in the kitchen sinks when the washing machine pumps the water out, which are above the former leak. First you can hear it bubbling a bit, then it comes up about 1/2 inch in the sink, stalls for 2 sec and the drains out just fine. Smells bad and the water isn't clear with bits of stuff in it. No other back ups in the house. And there's no water backing out where the washing machine hose is stuck in the drain pipe.Is that a regular clog and I need to get someone to clean the vent?
