We built our home in 2000 and last Sept we had to replace the pump in the dedicated sump that drains the stationary tub and washer and is tied in to the floor drain. All is ejected up and out of the basement and into the leech field. Problem is when the pump fails the water comes up through the floor drain and floods the basement which is to be expected, but the water pools under the hot water heater, the basements stairs and in front of the steps. Does that mean that the basement floor is pitched wrong? and what can we do about it? Thanks.
