septic tank odor in bathroom sinks

[joker1234]

I just purchased a newer home that has been empty for about 18 months. There is septic tank odor coming from both of the sinks in the master bath. They are the farthest away from the septic tank it self. There is no odor from the showe or tub in the master bath or from the tub and sink in the other bathroom. Any sugestions on how to resolve this?

* There are multiple vents in a house. When a toilet is flushed and water goes into the drain pipe, the space behind the water in the pipe needs atmospheric pressure to force the water down the drain, it gets the pressure through the vent pipe.
* When a vent is clogged, a vacuum is created behind the water in the pipe. That vacuum normally gets the pressure from a vent pipe. If that pipe is clogged, the pressure comes from the nearest source, in your case the master bath sinks.
* Water in the p-trap is sucked out by the vacuum. Therefore, you don’t have the water in the p-trap to block the septic odor.
* Good luck… Adios… Jasper…
