Hello,

I recently purchased a 4 yr old home. During inspection, Home inspector raised a concern that basement drain (which has clear out) always has standing water in it. We took some water out (almost a bucket) and it came back again. We called the plumber as he said there might me some blockage in the pipe and whipping tile and want to run a camera test.

My question is, is it common to have standing water in the basement drain? Where does the water came from even when we removed it? Should I be worried and get it more inspected?

What kind of drain is it ? Can you post a picture of it ? Is there a pump that pumps out water to the outside of the house ?

Back to you

You need some water in there for the trap. However, a bucket full is suspicious. Where does this drain line go? Is it connected to a basement drainage sump?

Yes, it is suspicious to me as well. Bottom of the drain is connected to main drain for clear out which is capped. Other end goes to sump pump, which I think is blocked. My concern is where is this water coming from? Is my Basement full of water!

Call your local plumbing inspector and ask him if your house might have a HOUSE TRAP. Here, it isn't common, but there are still some towns that require installation of a house trap... keeps sewer gasses from the sewer mains in the street out of the house. There is usually a cleanout or two associated with these... see image.
