I am getting ready to install a battery back up sump pump system in my basement, and was down there looking everything over before I get started. My sump pit always has water in it no matter what so I am assuming this is normal ? The pump will turn on, drain then will kick off then water fills back in from outside the pit causing the pump to again kick on. I do have a check valve in the discharge line so I know the water is not comeing back in that way. If I unplug the pump the water level stabilizes at a certain level, and does not continue to go up ? I was thinking the float adjustment is off, but it seems the problem is the water line is higher then the travel range of the float. I temporiarly put two blocks of wood under the pump, and the pump has not come back on, and the water level is at it's normal height. Is this Ok to do, or do I have other problems here ? Thanks in advance for any help !!
