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.

What is the expected life of a backup system? Not the battery--that's about five years--but the pumping system and electronics? Mine is twelve years old. (I have the midrange Basement Watchdog.) Should I replace?
Shane

Answer
The estimated life expectancy of any sump pump or battery backup system is about 7-10 years, though I have heard of some lasting 15-25 years. As long as you keep an eye on it and do as all manufacturers recommend, by inspecting it every 3-4 months to insure that everything is operating properly and the basin is free and clear of any debris that may impede it's operation, the choice of replacement is yours.

How often is it typically necessary to add distilled water to this battery?
Darrin

Answer
You should check you entire system, i.e. primary pump, backup pump and floats, controls, and batteries for the correct acid level and to insure that the terminals are clean AND also the basin to insure that it is clean and free of any debris that may impede the operation of the pump(s) or float switch(es) every 3-4 months according to all manufacturers.

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

Read Response +
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.

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?
Scott Mueller

Answer
Yes, the controller will keep the battery charging and the pump running indefinitely if needed. This is true for the Basement Watchdog model BWE and the BWSP stand alone battery backup systems as well.

Hello Jim, If I purchase the Basement Watchdog BW4000-Kit can I add a second battery and wire them together? Would the charger supplied be sufficient? I'm looking for more backup time. Thank you

What is a reasonable expectation for pump life and battery life? Our environment is occassional pump use during the year with considerable use for 2 to 3 days a couple of times per year during storm.
Bob Peters

Answer
Pump life expectancy should be a good 5-7 years and battery life is typically 2-3 years.

If & when the primary pump fails (hopefully in many years) can the backup pump continue to be used with a 'new' primary or are they connected in some fashion? Also, does this include the battery box? Do the primary & backup have separate plugs, I want to connect them to separate circuits in my basement. Thanks!!
Dave Jarvas

Answer
If & when the pump should fail, you can replace the primary with a Basement Watchdog model BW1050 primary pump with no problem whatsoever. The backup pump is another matter. If any backup component should fail, you would need to contact Basement Watchdog for replacement as we only offer the complete kit. The battery, acid and battery box are included with this kit and each pump does have a seperate cord and plug, so you would be able to connect them to seperate circuits, which is always an excellent idea and recommended.

You say that the battery is a 735 hour battery. Does that mean it will run for 735 hours? That seems like a really long time...something I'd be excited about....but a really long time. Can you clarify?
Steve Brandenburg

Answer
The battery is a 7 1/2 (7.5) hour battery meaning it will run the backup pump for approximately 7.5 hours continuously or approximately 18-24 hours non-continuously on a full charge.

Will this work for sewage? I need a back-up solution for a sewage pump.
Joe

Answer
No, definitely not. We currently do not offer any backup systems for sewage applications. You might try contacting Zoeller tech support at 800-928-7867, Simer tech support at (800) 468-7867 or Wayne tech support at 800-237-0987 for more assistance. Your other option might be to install a standby GENERATOR that would automatically turn on and provide power for your pumps and other major appliances when you lose power from your utility for any reason.

Jim, How long is the battery good for? Hoping 7.5 hours. Can the Big Dog watch monitoring system be added to this? if so how much extra?
Shawn

Answer
the battery is a 735 hour rated battery, however keep in mind that the older the battery gets ans the more it cycles, the more the battery life is reduced as with any battery. In order to achieve the benefits of the Big Dog monitoring system, you would need to purchase the Big Dog System. the components are not interchangeable.
