When I flush the toilet, the bathtub drain makes a gurgling noise. There is not any water coming into the tub, but is the sign of a future problem?

Good morning Corole,

When a toilet discharges and runs down your pipes it creates a suction. This is why there are vent pipes to relive the suction and allow the water to run smoothly. When a vent pipe is blocked, the suction vents through the nearest fixture. In this case, making your bath tub "guirgle". Your going to have to get on your roof and check the exisiting washer vent. I have found everything from birds nests to dead critters blocking a vent. Shine a light down the washer vent and see if you can see anything that may be down there. If not you will have to run a snake down the vent. I would recomend renting a Rigid K-60 sewer machine for the job. Open the 4" cleanout located just outside your house and run the snake out from the roof vent untill you're past the cleanout. Hope this solves your problem, but if it don't, I'm as close as a click. Good luck, Tom
