If you buy one of these, do yourself a favor and throw out the flex drain hose and PVC it.
Mine has been running for around 8 weeks. Came home from work tonight to my pump wheezing and a sump with about an inch of water in it. First I think maybe it was due to evaporation so I start putting water in the sump. Then it hits me I just looked at it last night and the level was fine??? So I keep putting water in the sump then I hear water splashing behind the stand.
Pull the overflow off and there are 2 spots on the flex hose that are separated allowing water to poor out. 
Emergency trip to Lowes and now the drain is PVC'd.
