I'm not a plumber, just a long-time homeowner who has personally replaced several sump pumps.

1. The link you gave goes to a Sewage Pump, not a sump pump. A sump pump removes water collected under a home in a basement sump basin, not sewage. You can get a good one for under $150.

2. If you know you will be away from your home frequently for extended periods, I think a battery back-up for your pump (an alternate fuel source to run the pump you have) is a great idea. My friends who own vacation homes have back-up fuel systems. See what your plumber thinks of that.

Good luck!

@honibaker Do you have a suggested brand of battery backup pump? Don't know even where to start looking. Thanks.

@honibaker For sewage, is it also a good idea to have a dual pump in case one breaks?

I'm sorry....I don't have a recommendation. Maybe you could post another question asking for

recs? I don't need a back-up myself, since I really don't travel.

I am not familiar with sewage pumps (never had one), and would not want to guess about them.

Hope you can find a trustworthy plumber to help you.

My friends used to have a dual sewage pump system. Two pumps, two floats, two check valves. 2nd float set above the first so that it would activate if the first failed.
