When it malfunctions, it can cause sewage backup and flooding, leading to costly repairs and health hazards. Replacing a sewage ejector pump can be a daunting task, but with the right tools and knowledge, it’s a manageable DIY project. This comprehensive guide will walk you through the step-by-step process of how to replace a sewage ejector pump in your basement.
