I have an old pipe in the basement that was used as a drain off from a washing machine. When I flush the toilet upstairs I can hear the water gurgling in this old pipe. Why is that and how can I stop it?

Thanks,

Mike :confused:

Hi Mike,

A gurgle tells you that your system has a blocked vent and the system is venting thrrough the washer trap. Snake out the lavatory roof vent and I bet the noise stops. Good luck, Tom

Thanks Tom. One question, where is the lavatory roof vent? Is that the pipe on the roof of the house?

Hey Mike,

The lavatory roof vent is usually located on the roof directly above the bath room. Good luck, Tom
