Product Questions Answered by Jim, the Sump Pump Expert
I've owned and used Basement Watchdog battery backup systems for a long time and they have always performed very well for me but I see all these new systems with notification, self-testing and other nice features that would be great to have in a lower cost system. Will they ever improve or upgrade this system?

Looking down the road, if and when the pump fails / wears out, would I be able to replace it or do I need to replace the entire unit? Hence, would I be able to use the power inverter or controller with other pumps? Thanks.

The sump pump is in small room in the basement with poor ventilation. This system has a battery with a charger. Doesn't charging the battery release gases? Are those gases harmful when inhaled?

Hi Jim, I am looking for a battery only sump pump that will pump 1500gph and I see the watchdog. I am looking to use this with battery only because power is not available for this project. I want to connect two batteries in parallel to give me more amperage. I am going to tie solar panels for charging purposes. My question is will it run if AC voltage is not there or will it turn on and off as water come in and raises the float? Thanks

Hi Jim, can I use the Basement Watchdog BWSP - Special Backup Sump Pump (1730 GPH @ 10') with a pedistal pump? I have considered the submeriable main sump pumps, but I like the ability to control the float on/off more with the pedistals for longer run times. Thanks!

I have a customer who wants to install a Sump Pump w/ Battery Back-up in an open stairwell. The battery and controller will be approximately 14' away inside the residence. Can I cut the control cable and splice the same gage wire to the inside location? Or will I new a heavier gage because of DC voltage?

Is the PeakFlow 12v maintenance free deep cycle 120ah AGM battery compatible with the WatchDog BW4000 pump system and charger ? Will it last 7.5hrs in continuous mode like the battery sold with the kit? What is the shelf life if used 2x a year intermittently for 1hr. for

If the backup pump is activated due to heavy water flow (to help the main pump) and the AC power stays on, will the system keep charging the battery to allow the backup pump to keep running indefinitely?

will the watchdog special backup pump work with an existing sump pump? A few years ago we tried to add a battery backup and it wouldn't work with our current pump. So all I need to buy is the battery backup and install to my current sump pump? Thank you, Shari
