Sewer and Drain Odors

Are you noticing sewer odors in your home? Besides being very unpleasant, it can also be a symptom of a plumbing problem.  If you notice sewer odors in your home there are several things you can check:

1. Dried Out Floor Drain Trap. Like the trap in your sink drain, a floor drain has a curved section to allow water to rest between the inside of the pipe and the outside air. This "trap" of water is designed to prevent sewer gas odors from entering the home. Pour a bucket of water down the drain to refill the trap.

2. Missing Clean-out Plug Inside the Floor Drain. If the floor drain trap does not stay filled the reason is usually a missing drain plug. Remove the grate covering the drain and check to see if there's a drain plug inside the drain bowl. If the plug is missing you can purchase a replacement plug at most hardware stores.

3.  Unused Toilets. When toilets go unused for a long period of time water in the trap can evaporate. Flush toilets at least every couple of weeks tol refill the trap.

4. Worn Toilet Wax Ring. When a toilet is attached to the floor a wax o-ring seal is used to create a watertight connection by sealing the toilet flange to the toilet base. If the wax ring cracks, sewer gas will escape from under the toilet. If the ring is broken, the toilet will need to be removed and and the wax ring replaced. Always install a new wax ring when replacing or moving a toilet. Also check whether the toilet is loose on the base, if it is, shims can be used to ensure that a rocking toilet doesn't break the new wax ring.

Other possible causes of sewer odors include a broken or cracked sewer line or, less frequently, a loose pipe joint in an interior wall. If you've checked all the possibilities above, M/R Plumbing can help you track down the cause.
