If your sewer pipe exits the house above the floor line and you have fixtures in the basement then you have a ejector pump. Regards, Tom
Could the sump pump be involved? Your thoughts? Tom

OK, I know I have a sump pump, but will look today and see if I have a sewage pump.

Meaning, making the noise? No, definitely not coming from the sump pump. Not sure if you meant something else though.

Just for your information. Sewage pump will look like sump pump but will have more pipes.

One more time!
If your sewer pipe exits the house above the floor line and you have fixtures in the basement then you have a ejector pump.
Don you have such a pump? Back to you, Tom

It do not believe I have one. I only have a sump pump, and believe my main sewer line is in the basement.

Could it be a "banging" that you hear? If so it could be the check valve c losing. Your thoughts? Tom

OK, if that is the case I would be able to hear the knocking standing next to the sump pump? I thought the sump pump was for ground water, not drain water from the plumbing pipes? Please advise and Thank you.

Sump pumps are ,indeed, for ground water. I'm just exploring possibilities. How about an PRV (pressure reducing valve, (see image) do you have one of those next to where the water enters your house? Let me know, Tom
