sump pump - best gas powered backup power source option
Long story short:
I built my home 4 years ago and have a full basement. The sump pump runs constatnly. I have had 2 (minor) floods aleady due to sump pump failure. I installed a triple stairstepped system - consisting of 2 electrics and a (pathetic) electric back-up. I have not flooded since although the 2nd electric saved me twice already - once when the primary float malfunctioned and once when the primary float's connector rusted through and the float was floating on the top of the water. I am finishing the basement now and want more security for power outages (the basement can flood in a matter of hours).
I am looking at gas powered backup that comes on automatically when the main power fails. I only want enough power to run the sump - not the whole house. What is the best and most economical option for this? I have a friend who is a certified electrician and can do the install. Any suggestions would be helpful. Thanks
How many sump pits do you have?
I have two pits. The main one is connected to the footing drain tile and then to a dedicated back-up pit.
I now have a decent sump in the main pit ( a 3/4 h.p. Flotec) and a Big Dog AC/DC back-up sump in the over-flow pit.
The Big Dog is not a very powerful pump, but I chose it because it operates both as an AC back-up pump in the event the main pump fails for any reason, as well as a DC pump in the event of a power failure. That kind of eliminated the need to have another AC pump.
For long power outages I doubt any battery powered pump will do for longer than a few hours, but you can always get a second battery. A gasoline powered generator that you could light up yourself or, if you have the budget for it, an automatic Generac natural gas power back would be the best.
I am still hoping someone digs a foundation lower than my footings somewhere or that the water table drops somehow. This is a tough problem to deal with and an expensive one in terms of energy consumption and equipment.
