Basement flooding - sump pump on continuously
I have experienced some small basement flooding in my 1.5 year old home. The sump pump has been working continuously and with all the rain here in the midwest it would go off every 3 to 4 seconds. Now it is going on every 10 to 15 seconds as the rains have stopped.
A few days ago we had small puddles in the low spots in the middle of the floor by some seams. This was weird as it was not by the sump pump or near the wall or corners. I dried this up with towels, fan, and a dehumidifier. The builder said that there is too much "pressure" and that the sump pump could not keep up and that the moisture cam up from the ground through the seams.
Does his explanation sound accurate? Is the builder responsible for fixing this? What can I do about this to prevent future problems when I end up finishing my basement?
Any help / suggestion is appreciated.
Thank you,
Will
