In any case, it appears we have a situation where as much as an inch of water at the far end (give or take a little) would have to run UPHILL to reach the sump. Now I should also mention that this basement is built on pure sand (literally - there is a sand mine just a mile or so down the road) and drainage is very good, so I don't really expect that there would be too many situations where the basement might flood - but on the other hand, if the unforeseen ever did happen, it would be much easier to deal with the problem if the water naturally ran toward the sump. I should probably also mention that this basement was constructed with extra headroom, so pouring more concrete over the existing floor would be doable (in terms of not losing space). And, the general contractor seems like an honest person, but I'm not sure that he's aware of this problem yet.
So I have three questions:
1) Realistically, is this anything to worry about? Or am I concerned over nothing? Should I keep my nose out of this?
2) Would this violate any codes or building standards (in other words, is this something a local government building inspector would take an interest in if they knew of the problem? This is in Michigan, if that makes any difference).
3) If there is a problem here, what would be the best approach to take with the contractor? Should my family member insist that a new layer of concrete be poured that slopes toward the sump, or would that create other problems? Would the excellent drainage of the soil indicate just leaving well enough alone? If you are a contractor, would you categorize this sort of defect as "serious" or "minor"?
4) If additional concrete should be poured, is that something that the homeowner would have to bear the expense of, or would that be considered a serious enough flaw that the concrete subcontractor should be required to fix it on his nickel?
Neither I nor the family member in question have ever done anything like this before, so I guess what I'm wanting to know is whether this is a significant problem, or something fairly normal? I have a feeling the contractor is not going to think it's anything to be concerned about, and if that is the case, is it worth making a fuss over? Time is of the essence here - if the situation is going to be rectified, it will be much harder to do so after another week or so.
