1.) Water-powered sump pump (http://www.basepump.com ). Has anyone used/heard good or bad things about this product? Would you recommended another brand? I checked with my local water department and they said in the event of total power loss in my area (say in a hurricane), I have two 3 million gallon water towers servicing my part of town (he said we'd have AT LEAST several days or more or normal water pressure). I prefer this method as it don't have to worry about batteries dying, needing maint. etc. Once my pump does start to run it runs fairly often, about 20 seconds every few minutes, so I don't think batteries would last too long (7-12 hours tops).
2.) Battery backup sump pump. Watchdog seems the popular one here. If I hear bad things on the water powered pumps I would go this route. Installation would be easier (no water service tie in). However run time concerns me. If my pump runs 20 seconds every feew minutes I think that's on the 7 hour time frame for battery life.
I come to this group looking what my best option is. Once you factor in batteries both solutions cost nearly the same. Thanks!!
