Hello, I have a rather large home and there is a sewer smell in my most used bathroom. I poured water in the tub and sink drain and the smell went away for two days. Everything is also draining properly. I tried to snake the vent pipe and it stopped at the bottom before it 90's over. Someone wants to replace all the pipes but I have heard it is an easier fix more often than not. Thanks for any help in advance.

The odor can usually be traced to a bad wax seal on the toilet, scum build up in the sinks overflow, or a dry trap on a fixture that's not used regularly.

It's a new wax seal. I replaced that a few weeks ago. It's all rather new pvc pipe but with very little existing cast iron that is tied into the pvc. I tried pouring water in the tub and sink s and it did go away for two days. Thanks

Next time it smells just pour water in the sink, not the tub and see what happens. You'll need to find the problem before it can be rectified.

If you have a septic system, try CCRL. I use it like every two weeks, and it supposedly puts the necessary bacteria into the septic system to eat whatever smells.

Is there a shower and/or tub that is not used as much? I have an old bathroom with shower, separate tub and sink with the same symptoms.
If the toilet and drains share the same line, it is possible that flushing the toilet pulls the water from the traps in the other lines. Maybe not in one flush, but several, or one fixture gets used less and suffers the loss of water in its trap over time more than the others.
EZ, cheap fix is to run water down the drain after every flush,... or when you smell it. Since it goes away with just some water in the traps, this is more likely than the next possibility of cracked line letting gas in the room.
