About six months ago we had our entire sewer system pipes replaced in our home. Everything good until now. When the clothes washer is draining the toilet bubbles as do other drains. We had Roter Router out yesterday and they used a water jet to clear the pipes and the water was flowing correctly. The toilets flushed and all seemed fine until I tried washing clothers this morning. During the drain cycle again the bubbles. Our plumber checked the drain vent on the roof and it was fine. This Village is on a septic system and the septic is cleaned out once a month. So where do I go from here? The people in the house next to me say that the toilets are slow flushing and they have to flush them several times. All upstair toilets in both houses have no problems. What do I do?

I'm confused! In your title you say the drains "gurgle" which indicates a vent problem.
However, in your post you inform us that it's "bubbles" that the toilet and other drains are producing. Ya can't have it both ways. Gurgles indicate a vent problem while bubbles indicate a drainage problem. Would you care to clear that up for us before we continue? Regards, tom
