Q: 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
by Walter from Michigan on March 12, 2012

A: 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.
by Jim, Product Expert

Q: Is the installation manual and dimensions available on-line so I can se if this will fit in my application?
by Ralph Hirsch from Massachusetts on December 02, 2011

A: Yes it is. Please click HERE, and then scroll down a bit and click on the "Specs" tab. You will then see a "Download Documents" box on the right side of the page where you will be able to download a pdf file of the owners manual, which includes all of the dimensions and installation instructions.
by Jim, Product Expert

Q: Can I use 2 batteries connected at the same time for extended extra protection time on this Glentronics BW4000 unit?
by Zach from Maryland on October 29, 2011

A: 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.
by Jim, Product Expert

Q: Is the exit pipe 1 1/2' pvc? does it have any
fittings attached?

by Al Bielunis from Massachusetts on May 04, 2011

A: 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.
by Jim, Product Expert

Q: 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?

by Chris from Connecticut on April 19, 2011

A: 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.
by Jim, Product Expert

Q: 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!
by Chad DiFranco from Ohio on April 08, 2011

A: 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.
by Jim, Product Expert

Q: 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?
by Pete from New York on March 23, 2011

A: The BW4000 comes with a 1/2HP BW1050 primary pump rated at 32000GPH at 10 feet of head and a BWSP battery Backup pump rated at 1730GPH at 10 feet of head. The SPD-BW4000KIT also includes the battery and battery acid.
by Jim, Product Expert

Q: How small of a footprint does this unit take? My sump hole is square shaped and 11in by 11in.
by Mike from Connecticut on February 01, 2011

A: This Basement Watchdog combination system is compact and 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.
by Jim, Product Expert

Q: Do I need a check valve with this unit?
by Elliot from New Jersey on January 27, 2011

A: These combination pump systems from Basement Watchdog have built-in check valves. An additional float switch is not needed.

NOT A GOOD SYSTEM

First of all I've had this system in my house since September last year 2011, I am currently on my 3rd pump!! If you have a crock that fills up with a lot of water during a rain storm THIS SYSTEM IS NOT FOR YOU!!! This system has in my opinion a very serious design flaw, the float switches are not long enough. Meaning that the pump will cycle on and off far too many times during a storm, leading to a pump failure and a flooded basement. This is suppose to be the best system they sell but the backup pump isn't even the best backup pump they have, so save your money look for a better way or ... more

Great Company & Product

We received in the pump system in 2 days, and since the old pump was acting up we were happy to see that it was here so fast. Was very easy to install. Very happy with company.

Ready For The Next Irene or Power Loss....Whichever Comes First!

Okay, so I had a basement watchdog backup in my hand back in January of this year. I put it back on the shelf thinking that I'd wait until 'later' when I may actually need it. Well, 'later' came in August in the form of Irene. After losing power, and hence my sump pump, Irene felt the need to flood our finished basement. Our basement is now back to normal with my BW4000 standing guard. My BW4000, Sumppumpsdirect, and the installation video are all AWESOME!!! Don't be like me and wait until 'later' to be prepared. You will regret it if you do!!

Who Let The Dogs Out?

Pet dogs sometimes make a watery mess on floors. Even a good watchdog has accidents. They all require training, bonding time and plenty of food to keep them strong and healthy.

But there is one watchdog that I just placed in our basement that for the most part I can leave unattended and know that he will not leave a mess on the floor. He even trains a smaller dog to back him up when necessary.

We have two separate, independent sump pumps in our large basement. While neither one had a battery backup, we would use a generator should the electrical power go out dur... more

Combo Basement Watchdog

Fortunately I haven't had to test this unit as I could have used during Hurricane Irene but installation was easy & instructions were very clear. The whole system seems well designed & sturdy & in testing manually, ( haven't had a lot of rain since the hurricane!) pumps were strong & much better than my original system. I am confident now that this system will protect my basement even when no one is home or while sleeping & gives piece of mind.

Watch the Installation Video

I purchased the Basement Watchdog BW4000 (primary and backup combo) and installed it myself. The installation video is very helpful (aside from the really annoying music), but chances are your installation will not go as smoothly. I have a radon vent fit into my sump and that complicated installation (not accounted for in the installation video). If you have basic plumbing skills you'll be ok, but even if you don't have a radon vent in your sump, don't kid yourself - installation will take longer that what the video says.

Highly Recommend

I just installed the Basement Watchdog sump pump unit prior to hurricane Irene and thankfully I only had a small amount of water in my sump pump well.

The following week my area in PA got another 7" of rain from the tropical storm Lee and again the pump only turned on a few times to empty the sump pump well.

I am not able to provide any long term use report, but I am very happy with this unit. It is well made and it was easy to install and I am glad that I got the battery backup unit and the optional battery. It certainly gives me peace of mind that I will ... more
