Q: 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.
by Dennis H from Virginia on September 01, 2016

A: Liberty did recently upgrade the charger in this system so that it would be compatible with wet cell or acid base AGM batteries. I apologize for any confusion.
If you have any other questions, please let me know.

Q: 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????
by Mark F from Wisconsin on April 10, 2013

A: 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.

Initial Impression Is Very Good
The pump arrived 1 day after I ordered it, Fully assembled model thus it was very easy to install. Quite operation, Appears to be of very good quality, and was a relatively good price compared to other US made pumps of similar design and function.
Pros: Price, Easy To Use

Verdict Still Out
Bought for the battery back-up and thought I would have no problems if I bought he combo pump. Very easy to install and worked right away. However the following week the main pump would just hum but not move any water. The back-up pump and alarm worked great. I pulled the unit but could not find any problems and reinstalled it but the main pump still only hummed. I unplugged the man pump as I had other things to do for a few days. When I got back to handle problem and plugged in the main... more

John,
Sorry to hear about the issues you're having with your pump. You may have been experiencing air-lock, based on what you described.

A 1/8” anti-airlock hole should be drilled in the discharge pipe just above the pump’s discharge outlet to prevent pump “airlock” Pump Manual

Great Combo Setup
I replaced a very unreliable Basement Watchdog combo unit with this -- I like it much better!!! Primary pump is extremely fast, the backup is good. I like the float switches much better. Hookup is very easy. It comes with 3 sets of instructions -- one set for each pump individually & 1 for the combo -- found myself jumping back & forth a lot. One comprehensive booklet would have been better.
Pros: Price, Features, Quiet, Reliable
Cons: Bad Instructions

Peace Of Mind....buy It!!
I moved into a house in the winter so i didn't know how much the pump ran in the spring. let me tell you, it runs a LOT in the wet season. As soon as I saw how much it ran in the spring I wanted to replace the cheap (and loud) Walmart pump with something reliable. Good thing I replaced it with a quality pump and battery back up pump. 2 DAYS after I installed it the power went out and the back up pump worked great all night. Worse yet, in the first 6 WEEKS we lived here we lost power 4 times... more

Combo System
The pump and backup system was easy to install. I did have to trim the pipe to match the height to my output pipe and the instructions want you to put the battery controller on the battery case and I wanted to locate the battery controller near by but not on the case. The wires from the battery to the controller were a bit too short so I couldn't put the controller where I wanted it. Also I thought the alarm would notify me of excessive water during a power outage and instead it goes off if the... more
