Basement water due to heavy rains... no sump pump presently.

Project Location in Lafayette

We noticed that the basement was flooded as of this morning- June 7th. Had not been flooded prior, even though we have had an excessive amount of rain We have a sump pump in the laundry room that is encased in a concrete trough. It is full to the brim and the water in the sump pump is blue from the water draining from the washing machine. We tried bucketing out a lot of the water but it would just keep filling up Also, there is water all over the basement floor that is not blue - it is clear. A good half of the basement is flooded. At this point we don't think it's coming from the sump pump not working because of the difference in color. It is flooded in the workshop, the laundry room, part of the storage room and a good part of the family room downstairs. The house relies on well water and I don't know if it's a possibility that the underground well has become overfilled and is possibly oversaturating the house

Sump pump itself appears to be working fine, though it looks older than it is and covered in sediment, so maybe it should be cleaned/serviced. Check valve may need replacing, we hear water run down it after the pump runs for 10 seconds, but pump doesn't cycle too frequently so it must not be too much water that returns. There is a very strange gurgling sound though that continues for around 30 minutes after the pump runs though, which is mysterious. The pump discharge point is super jenky and freezes up when it gets cold out, looking for a solution for that. The sump pit does not have a sealed cover and we would like to add one that prevents radon gas from escaping while allowing it to still work as a floor drain. Finally, we don't have a tile drain system, and wondering if we should and what that would cost. The sump liner is old corrugated metal and maybe eventually needs replacing, want to understand what kind of an effort that is. Thanks!

Sump pump is "backwashing" Basement is leaking

Project Location in Lafayette

We had flooding in our basement last week in a finished bedroom. We've already ripped out all the carpet and padding. There was visible mold on the carpet right against the wall, which leads us to believe there have been issues for many weeks. But that area was behind the bed and it wasn't until last week that it was suddenly wet across the entire floor. The water all seems to becoming in at the "seam" where the walls meet the floor along the east side of the house. There doesn't appear to be any wetness or damage in the walls. We don't know if it's hydrostatic pressure and coming from below or coming down from the surface (about 6' up). But after we ripped up the carpet and repositioned a downspout that we discovered was dumping right above, it has stayed dry--and we had two solid days of rain. So it may be that it's coming from above. We need someone to diagnosis the problem/cause and provide an estimate for repair. This may also involve mold remediation?? THANK YOU!

Have a "floating" wood floor in my basement. water is coming in-from where?- and newly laid carpet and pad are wet. Have a sump pump which is working or opposite side of basement. Maybe leaking in from foundation walls??? Don't know.

Some moisture gathering along cove joints in basement after heavy rain. Already have a sump pump and drain tile system.

We are buying a home that has a lower level door/landing that has a drain to a French Drain on the landing that is either plugged or just cannot handle downpour situations. Current owner has a sump pump on the landing over the drain to pump water to yard if drain backs up but we would like to put in a pit/pump such that water directly flows in the pit (to the side of the door) and gets pumped out to ensure no flooding could occur with water flowing into the lower level door/room

Hi, My home is a split-level house and I am having a water control issue on the lower floor. In one closet, water is soaking the carpet. I have talked to a plumber and they said there were no pipes that could be causing the problem. The walls are also dry -- I suspect water is entering the house from underneath (if this is even possible). The carpet is so wet that pushing down on it causes water to squish out. Is this something you can take a look at and/or help with? Thanks
