Bathroom Plumbing Matthews, NC
The storage room was rarely used, causing the water in the floor drain p trap to evaporate, and when the trap dried, it lost its water seal, leading to a sewer gas leak. We added a lot of water to re-form the water seal, and installed the waterless trap seal, so that even if the water evaporates again in the future, it will not cause leakage of sewer gas.
