The four window well drains sound localized with the drainage problems. The situation with your pump would be likely the location of where the new pump was set or different float config that is allowing the pump to pump out the water table differently. It's always better to have a pump run continously for long stretches removing water than constant start and stop, start and stop. Not only hard on the float switch but it costs more electricity with that setup. I couldn't tell you how many sump pumps I have replaced where people think that you can set the discharge line 4 feet outside the foundation wall. They think water stays on top and never goes back to the lowest point, the sump pit.
