Sewage gas smell coming up in Master Tub
Hi everyone,
I have seen similar questions but am not sure if answer applies in my case. We recently built a house and began noticing a sewage gas smell coming up from our master bath tub. Shower is separate from tub. I also notice a gurgling sound in the master tub when we flush the master toilet, don't know if this is related or not. We have only been in the house 1 1/2 months, and the plumber suggested we fill the tub with water and let it drain, thinking that the p trap was empty, allowing gas from our septic system to come back up. We tried that and it worked for about 2 days and then the smell was back. Often I notice the smell most strongly when someone takes a shower, but also at other times. I saw on several posts that the roof vent could be the culprit, could we have a clog in the roof vent so soon after building? Any other suggestions? I should maybe mention that we have a 2 story house, and the master bedroom is on the second floor.
Thanks,
Stacey
