If the smell comes back within a few hours after pouring water into the drain, it is probably not just a dry drain.
Common reasons include:
- The floor drain P-trap is damaged or not sealing properly.
- There is a partial blockage in the drain pipe, allowing sewer gas to come back.
- The plumbing vent pipe may be blocked, so the gas cannot escape outside.
- There could be a loose connection or a leak in the drain pipe.
If the smell is only coming from the guest bathroom and keeps returning after adding water, don't ignore it. Sewer gas is not just an unpleasant smell—it usually indicates a plumbing problem.
My advice is to hire an experienced plumber through Fixydo to inspect the drain and vent system. Once the exact cause is found, they can fix it properly and permanently.
