Product Questions Answered by Jim, the Sump Pump Expert

Does this back up pump have similar specs to the Main 257 pump?

Zack T.

Answer

It's actually pretty close Zach. The main 257, 1/3HP pump is rated at 2250GPH at a 10 foot head lift while the 441 backup pump is rated at 1830GPH. In most cases, the backup pump will have a slightly lower pumping capacity than the main or primary pump. Also, since the backup pump is powered by 12 volts, the pumps are generally only rated in GPH capacity and not in HP.

I'm confused about battery specification for this. Your site says not to use AGM battery, but Liberty's site says you can. Why the difference in advice? Thank you.

If the 120 v pump can't keep up it sounds as if the battery backup pump will kick in---but the units share a common pipe so how can you add water /flow to an already maxed out pipe?? Would this not just increase head pressure on the battery pump causing it to work even harder????

Answer

Thank you for visiting Sump Pumps Direct. You bring up a very good and important point, Mark! Most primary (1/4HP - 1/2HP) and battery backup pumps discharge to a 1-1/2" discharge pipe and will be installed separately but due to the discharge system already in place, be piped or "Y'd" together. In MOST cases, the total pumping capacity by both pumps at the same time will be handled by that 1-1/2" discharge pipe and will not cause any extra stress or back-pressure on those pumps. That being said, for optimum performance of both pumps, they should be connected to separate discharge pipes. Again, that is not always possible. In cases of extreme high water tables and frequent possible flooding where high capacity pumps are required, you should definitely run a separate discharge pipe for each pump you have installed.
