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?

Answer
Thank you for your interest in Sump Pumps Direct. And funny you should ask, Simon! Basement Watchdog has recently updated the controller in the BWSP. The newly updated system has been on the shelves and in circulation for about a year now. According to Basement Watchdog, the updated controller has proven its reliability, having sold over 10,000 systems - with only 5 defective units to date.

While this new controller has some similarities to our previous one, some significant hardware and software changes have been made. Those changes include:

• Remote Notification - We have added in terminals which allow for remote notification. This system is now able to communicate with an Auto Dialer, Home Security System or other device, to alert home owners to problems or required maintenance

• AGM Compatible - The most popular revision allows the customer to utilize wet cell, or AGM maintenance free batteries

• Improved Charging System – Improved battery monitoring and charging system

• Weekly Pump Activation – The system will run the pump for a few seconds every week to not only test the pump but to also exercise it which will help prolong the life of the pump

Can you recommend an ACpowered sump pump with battery backup that would fit into a 14 deep x 12 diameter well? My current sump pump is a Ridgid Model SP500 12 hp, 60 hz, 120 volt, 3.8 amp. Thanks. Rick

Thank you for your interest in Sump Pumps Direct. The Basement Watchdog 1/2 HP Combination Primary and Backup Sump Pump, model BW4000 will fit in a sump pit as small as 12” wide and 14” high (the size of a 5 gallon bucket). It measures 18“ inches from the bottom of the pump to the top of the "Y" connector where it will be attached to the discharge pipe.
The Basement Watchdog 1/3 HP Combination Primary and Backup Sump Pump System, model DFK-961 will fit in a sump pit as small as 10” wide and 14” high (the size of a 5 gallon bucket). It measures 17-3/4“ inches from the bottom of the pump to the top of the "Y" connector where it will be attached to the discharge pipe.

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.

Jim, do you recommend placing a Sump Foot beneath a Basement Watchdog BW4000 - 1/2 HP Combination Primary and Backup Sump Pump System?
Bob S.

Answer
The only time you need to raise your pump is if you want to allow the basin to fill a bit more before it activates and you do not have float switch that can easily be raised instead of the pump OR if you have a dirt or loose gravel base in your basin and are afraid that the pump will get clogged easily. If you have a standard sump basin with a clean, flat bottom it is not necessary.

After the battery back up system kicks in and then the power comes back on, does anything need to be reset or does the primary pump automatically go back in to service?
Mark S

Answer
No reset needed, Mark. Your primary pump will return to service and the controller for the battery backup system will start re-charging the battery.

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
Walter

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.

Can I use 2 batteries connected at the same time for extended extra protection time on this Glentronics BW4000 unit?
Zach 
from Maryland 
October 29, 2011
Read Response +
Answer
Unfortunately, the BW4000 is not designed to accept 2 batteries. The only Basement Watchdog system designed for that application is the BIG DOG. This system is capable of accepting 2 batteries in parallel for twice the runtime, up to 15 hours continuous or 3-4 days non-continuous. If you should opt for this system, you would need to purchase a seperate primary pump.

The discharge pipe on this system is 1 1/2" and there is a rubber 1 1/2" union included to attach the system to your current or new discharge pipe.

Jim, Can I use a regular deep cycle battery with this system or do i need to use their specific battery? Also, what is the function of the battery probe, and can that be used on a deep cycle?
Chris

Answer
Per the instruction manual:
• The use of automotive batteries is NOT recommended.
Automotive batteries are not
designed for this application. They will only
run the pump for a short time and will have a
shorter life than a standby battery.
• NEVER use a maintenance-free or sealed
battery with this system.
• The battery fluid sensor and cap are designed
to fit the Basement Watchdog batteries.
Measuring the battery fluid is one of the most
important features of the system; since about
80% of backup sump pump failures are the
result of a battery that has dried out.

How often does the back-up battery need to be checked and/ or replaced. How do I know when it needs replacing. My basement has flooded twice in the past 6 months. Prior to that, we have had little trouble and have been in the house 9 years. My sump pump runs every five minutes on a rainy day. I am torn between purchasing this unit and the one glentronics offers called their Pro-Series. The problem with that one is that only plumbers can purchase it and install it. The first one that came out wanted $1,500, which included the product and the install. I do not know if their Pro-Series is worth it? Any help you can give me is greatly appreciated. THANK YOU!

Answer
The Pro Series is an excellent quality and is manufactured by the same company that manufactures the Basement Watchdog pumps. Any primary or backup pump system should be checked at a minimum of every 6 months. You should check to make sure the pit and the pump(s) are clean and free of any debris that can cause your float to stick and cause your pump to fail. Battery backup systems almost always will have alarm systems to warn you if your battery needs water or if it needs to be replaced. Some systems will even run your backup pump for a few seconds to verify it is operating correctly and warn you by another alarm if it is not. Also, please note that we do also carry some of the PRO SERIES pumps.

Jim, what is the difference between the pumps, (primary and back-up), in the BW4000 combination primary and back-up ($399.99) versus the model SPD-BW4000 costing $639.99?
