I'm sorry to hear of the problems you have encountered. We currently offer only 2 water powered backup systems, the Bur-Cam model 300402 and the Liberty model SJ10. Since the Liberty model is capable of pumping a higher capacity at 990 GPH (gallons per hour) as opposed to the Bur-Cam model of 317GPH, I would have to recommend the Liberty system. Please note that you DO need to supply a bare minimum of 20psi of municipal supplied water for these systems to operate properly. If this is not an option, you might check out some of these BATTERY BACKUP SYSTEMS or you may even consider a small STANDBY GENERATOR. The generator would also supply power to other critical circuits like you refrigerator, lights and heat automatically.
