Why did the customer contact us?
My basement is 34' x 25' and we have a sump pump in the corner which is plugged into an electrical outlet and no back up battery. The water ONLY came in from the window well inside the office and in the closet to the left of the sump pump.
We installed a Grate Drain system along with a trench drain and added a high water alarm to the grate sump pump and did a radon test to the sump pump system and added a new window well drain. To complete our healthy basement standard.
