i have one it seems to work pretty good. even has a drain line which is nice.
have to clean the intake on the pump occassionally or more than i like but does pretty good none the less. when the intake gets crud in it you get an
overflow issue in the collection cup. the cup wont overflow with the drain line
in a bucket but the waterline in the tank will drop. my hands get wet a few
times a day so mine is monitored pretty constant. if you are the same should be no problem if not could be as much as dropping the water level as low as you mount the pump. it would take awhile to drop so as i said if monitored
regularly you should be ok. just for reference i do have a job so being gone for 8 to 10 hrs a day has not been an issue.
