Customer complained of a sour/sewage smell from basement bathroom and utility area connected to it. The old lid was its gasket, and excess concrete was also keeping the lid from making a tight seal, leading to a sewage smell. We removed excess concrete, disconnected pump and removed the lid. We noticed an excessive amount of gravel in the ejector pump’s lid pit, which likely entered the pit during construction of the home. We gave an option to replace the pump with a high quality, liberty pump since we already had everything disconnected. The customer declined to have the pump replaced at this time. We added a high water alarm, replaced the lid, and reconnected the pump. We ran water until the pump cycled 8 times to ensure proper function. We then unplugged the pump and let water run to test the high water alarm. The high water alarm worked as intended. We then plugged the pump back in and ran water until the pump cycled two more times as a final test. Thank you!
