Legal Question in Real Estate Law in Maryland

I assume you are asking if you can try and force the sellers to rescind the transaction. The answer depends on whether you can prove that the sellers were aware of a flooding problem in their basement when they put the property up for sale, and failed to disclose it. You would also have to establish that your inspector could not have discovered the problem during his inspection. You can be sure that the sellers will deny they ever had a flooding problem if confronted. You can check with the neighbors to see if they ever acknowledged having one when they lived there, and if so, that might give you some basis for a claim.
