We have a well. Over the past month the washer will drain and the toilet will bubble. Would like to know what to do.

You have a partial clog in the drainage line. Let me explain what's happening. Your washer unloads. The discharge picks up speed and bangs into the partial clog in the line and starts to rebound back pushing a bubble of air ahead of it. This is what you see in the f toilet. Then, because it's not completely blocked the discharge drains away before anything overflows. This can only get worse. The drainage line that services the toilet needs to be snaked out or if you're on a septic tank it should be checked to see if it needs to be pumped. Hope this helps and thank you for rating my reply. Tom
