I have a 1960's (early) home with an unfinished, utility/storm basement which is 10' x 20'. I have owned the house for 8 months, and had a home inspection that did not find any problems with the plumbing. The water heater is located there as well as a furnace. There are two holes in the concrete floor, one has a float/ball valve in it. Where the furnace hoses run to. The other one is about 1 ft. up the grade and seems to hold water down about two inches from the cover/grate.
I have noticed a foul smell at times and recently after a large rain had an inch or so of water covering the floor.The water dissipated after about 4 hrs. and having a plumber snake the outside clean-out to the manhole 150' away.
The Plumber did not know what the second drain in the floor was for, and said I could fill it in with cement.
I started to get the water out with a sponge and small cup, took out a gallon and the water level did not change.
I then noticed a 3-4 inch pipe on each side of the standing water in the middle, like it was cut out or something.
I then had my wife flush the nearest toilet (upstairs) and I noticed the water level rise, or flow through the gap between the pipes or what looks to be a piece of pipe missing.
Is this some sort of vent that is allowing gases into the basement?

"I then had my wife flush the nearest toilet (upstairs) and I noticed the water level rise, or flow thru the the gap between the pipes or what looks to be a piece of pipe missing."
Have your wife flush down some toilet paper. This will tell you if you have a open sewer main in your basement. The hole with a float switch is a sump. Where's the sump pump? The other hole's somehow connected to the sewer line and until I found out more about it I wouldn't be filling anything with cement. My biggest concern would be to find out where the connection is that allows water to enter the hole when the toilet's flushed. Please let me know what you find out. Good luck, Tom

Thank you for your response. I have tried the test of having the wife flush the
Toilet paper. I saw no paper come through and today not a lot of rise in the water,
But a little, maybe a few tablespoons. Here is some more detailed info: the
Second drain (hole in concrete with what appears to be horizontal pipe on each
End with standing water in the middle) is 20" from the drain with the ball valve
and cleanout plug. the ball drain opening is 6.5 " hole in concrete and the
Second drain is the same diameter. Up the wall from the second drain is
Electrical outlet (conduit attached to concrete wall) is looks to be old or
Original due to it being two wire (no ground).
Could this be where the sump pump would be, did I mention that there is not a
Sump pump in the basement? The plumber (s) that I have had look at it says the
Hole is not large enough for a sump pump?
Thank you again for your attention.

It would be helpful if you would tell us what size3 the holes in the floor are. I think your plumber's wrong. A float switch just shouts sump pump at you.
The other sounds like a gravity sump to drain away any water that may built up in your basement. My concern is that it may not be trapped because it's for sure it's tied in with the main and may be allowing sewer gas to escape into your house. I would have that checked and corrected. Good luck, Tom
