What is the maximum diameter of this pump? If it doesn't fit next to my wired pump, how does it get mounted above? Also, I plan to have it installed in a combination pit fed by my laundry washer as well as the drainage pipes. Is it suitable?

Answer
The dimensions for the Big Dog backup pump with the elbow, are 7-5⁄8H x 9” W. The installation instructions, including the mounting configurations that can be used can be found HERE. Battery backup systems as well as primary sump pumps are not designed to handle the chemicals associated with laundry discharge and in most cases your warranty will be voided when installed as such.
I recommend diverting your laundry discharge to a LAUNDRY/DRAIN PUMP SYSTEM as these are designed specifically for this application and they will also greatly prolong the life of your sump system.

Answer
If you are somewhat familiar with plumbing and working with PVC, primer and cement, you shouldn't have much of a problem. The pdf of the owners manual is available for download on the PRODUCT PAGE to give you a look at the installation process. It can be found on the right side of the page under the "Specs" tab.

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

Answer
Per the instructions for the Basement Watchdog battery backup systems, DO NOT use a maintenance-free or a sealed battery. They are made of different materials and
will trigger a false “Battery problem” alarm.
A new Basement Watchdog 7.5 Hour Standby Battery, model 30HDC140S will run this system for a minimum of 7.5 hours continuously. However, most of the time the pump will turn on and off, and the battery will run the pump intermittently for days. In addition, the unique materials in the battery enable it to last for five to seven years in standby service.

I'm considering the Basement Watchdog SPD-BDKIT for $675. I see what appears to be the same pump (BWD12120C), without battery, for $479. So I figure the battery and acid must be about $200. I see the battery (30HDC140S) for $140 and the same battery with acid (SPD-WDBATTERYACID) for $250. Does that mean you're charging $110 for the acid? In one of the Q&A's, you say auto parts stores should have the acid for about $20. OK, what am I missing?

Answer
Everything that you see is true. Due to the corrosive and hazardous nature of shipping the acid, the cost is elevated. We sell the kit as convenience to those customers that want everything delivered to their door at the same time and we also offer the other options for those that don't mind making a separate trip for the acid to save a few dollars. And yes, most auto parts and big box stores should have the acid available for about $20. You do want to look for 1.265 specific gravity battery acid and it will come in a 6 quart box.

what is the minimum diameter and depth of the sump pit in order to use an existing plus battery backup unit?-

Answer
Due to the design of this system, it can be installed in a couple of different ways. For narrow pits, approximately 12 inches in diameter, it can be installed to sit just above your primary pump as long as you have enough depth (22-24 inch minimum). For a standard sized pit (18 inch diamer by 24 inch depth), it could be installed to sit next to your primary pump.

I have just had a Little Giant pump installed along with the drain tile. On installation they have installed a 2nd line to the outside for a battery backup pump. How hard are these to intall? the company I used want $995 to install the battery backup. Please let me know do you have instructions that I could look at?

If you are handy at all, they really are not that difficult to install. Instructions are available to download and view at http://www.sumppumpsdirect.com/Basement-Watchdog-SPD-BDKIT-Sump-Pump/p1902.html. Once there, click on the "SPECS" tab and locate the "Download Documents" box on the right side of the page. There you can download a pdf file of the instruction manual which includes the installation instructions.

Answer
The battery charged and charging LED’s will alternate during normal charging operation. This is normal. If you're concerned about the loud humming, you could call Basement Watchdog tech support at (800) 991-0466.

Is the 6hr or 7.5hr battery included with the Big Dog kit?
Rob Johnson

Answer
The Big Dog kit includes the 7.5 hour battery and acid. You also have the option, with this kit only, to add an additional battery, connected in parallel for additional battery run time, however keep in mind this will also lengthen the charging time.

a couple of questions for you Jim..... Shopping for a battery backup system and considering either the Stormpro 2100GPH (SPD-STORMPRODCKIT) or the Big Dog (BWD12120c). I have read reviews including some mixed on the Big Dog but like the idea that I can add a second battery for extended pumping time if needed. Can you add a second battery to the Stormpro and if so what is the projexted time/life? Any thoughts or concerns with either one system over the other - I have read the reviews. Thanks Jim, David

Answer
Yes, you can add an additional battery (in parallel) to the StormPro system. It would extend the battery run time to between 15 & 20 hours, however, please keep in mind that it will also take longer to charge both batteries.
Both systems are excellent and I would recommed either one.

To be completely sure your backup system is fully functional during a power outage or weather event, these systems need to stay plugged in at all times.

If I buy a Basement Watchdog pump do I need a Basement Watchdog battery?
Karen

Answer
You can use any deep cycle marine battery, as long as it is not maintenance-free. However, there are several advantages to using a Basement Watchdog battery. The Watchdog battery accommodates the system’s fluid sensor which will sound an alarm when the battery needs water…a very important feature, since a dry battery will not perform. In addition, Basement Watchdog batteries run longer per charge, and last years longer. A typical marine battery will last 2-4 years, while the Watchdog battery will last approximately 5-7 years. Basement Watchdog batteries are shipped dry (without acid) so they stay fresh on the shelf indefinitely, while wet batteries have a short shelf life.

Update 11/16/15: Basement Watchdog has changed this requirement around 2013 and their backup systems will now accept maintenance free batteries. Please refer to their updated installation manual for instructions on the proper method for this battery installation.
