Can I run my sink & disposal into my basement's sewage pump?
My basement has a bathroom in it that uses an ejector pump. It works great.
Meanwhile, my kitchen sink & disposal are in the opposite corner from my sewer line to the city. The long travel distance causes it to get backed up. (The kitchen's sewer line is practical flat in various places.)
If I can safely run my kitchen line into the ejector pump, it should significantly reduce the tendency of my kitchen to get backed up - assuming the ejector pump itself can handle it.
