Really think your tanks will suffer any affects for the pumps being off 2.5 hours? $270 seems quite a bit for something that's probably a non-issue. I've done maintenance that lasted close to that with no problems.

Might want to consider something that would last longer such as Niloc suggests.

BTW my backup plan is an inverter I can plug into a socket in the car. Run a extension cord into the house and start the car when necessary. Will be picking up a small genset this spring for the travel trailer so would then have that available. Realize any of this would only work if someone was home.
