Southside Plumbing was out previously to mitigate a sewer gas smell. An empty p trap was found under the stairs and filled on the previous visit; the trap still currently has water in it. The sewer gas is still coming into the structure through another location. There is a sewage ejector pit with 2 pumps also located under the stairs. The sewage pit was cleaned off with a shop vac and a cover for one of the pumps was found to be loose and not sealed to the main lid. Every opening was sealed using silicone sealant to create an air tight seal and the loose lid was tightened.
