Top Reasons Your San Antonio Home Has Sewer Smells Indoors
If your home suddenly smells like sewage, it’s more than an inconvenience — it’s a sign something in your plumbing system isn’t functioning properly. San Antonio homeowners frequently experience indoor sewer smells for the following reasons:
1. Dry P-Traps
Unused sinks, tubs, or floor drains allow sewer gas to rise into your home.
2. Blocked Vent Pipes
Plumbing vents release sewer gases outdoors. When blocked by debris, animals, or weather, gases instead move inside.
3. Damaged Sewer Line
Tree roots, cracks, or collapsed sections of pipe can cause odors.
4. Loose or Faulty Toilet Wax Ring
A deteriorated wax ring lets sewer gas leak around the base of the toilet.
5. Clogged Drains
Organic buildup in kitchen and bathroom drains creates strong odors.
