just like the tunze stream pumps can take the adaptor that allows for a battery to take over if the power fails, tunze has a new range of return pumps that george now has on order. basically it will be the same....a return pump that you buy, purchase the extra battery connector, go to a1 radio buy a house alarm battery and trickle charger and you away...... the pump will run on mains power and will be trickle charging the battery the whole time......if the power fails the battery kicks in and the pump keeps running........no down time. i ran a 6055 stream on a 12volt battery on itls lowest setting for 5 days....it could have run longer but i was on my way to mauritius so i had to turn it on again to charge incase something happened when i was away |
