Best Pedestal Sump Pump

Learn More About Zoeller 84-0001
Expert Review
If you haven't heard of Zoeller Pumps before, you probably live in an area where sump pumps aren't needed. They have been making pumps for the last 75+ years, and if you haven't owned one, you probably know somebody who has. Zoeller is one of the largest manufacturers of pumps in the US. They stand behind their products and offer a wide selection of sump, sewage and utility pumps. This Model M84 gets our recommendation for Pedestal Pumps for a few reasons. They don't call it the Zoeller "Old Faithful" Cast Iron Pedestal Pump for nothing. The cast iron pump housing & base construction w/ PVC column minimizes corrosion in high mineral content water and the permanently lubricated upper sleeve bearing w/ lower bronze bushings offer quiet, smoother operation for extended pump life. Pedestal pumps are becoming less and less common, but there are still options out there. Try the M84 Old Faithful from Zoeller, it's the best pedestal pump we have to offer.

Best Cast Iron Sump Pump

Learn More About Liberty Pumps 257
Expert Review
Built in the U.S.A., this Liberty model 257 is a well-known name among plumbers and is a superior pump for the money. This cast iron pump is very efficient with 1/2 the running and starting amps of most other 1/3HP pumps in the same league and with a pumping capacity of 2700GPH at a 5-foot lift and the magnetically operated vertical float switch, this pump is one mean sucker! The 257 will handle any light duty applications with ease. Unlike many other pumps out there, this pump features a 16-gauge quick-disconnect 10-foot power cord for easy replacement if necessary and upper & lower ball bearings that allow for a smoother and cooler operating environment which translates to a longer motor life. Coupled with a 3-year warranty, this pump gets our recommendation.

Best Battery Backup Sump Pump

Learn More About Pro Series PHCC-2400
Expert Review
This system will blow you away for the cost and the features included. The Pro-Series PHCC-2400 Battery Back Up Sump Pump System will evacuate approximately 40 gallons per minute at a 10-foot lift! The 13-amp battery charger has the ability to charge standard & maintenance free batteries and quickly recharges the battery when power is restored. One of the great features of this system is its ability to run on 120-volt AC power when power is on. It switches to 12-volt DC battery power when AC power fails, automatically and it includes an exclusive monitoring system w/weekly self-test. This system can also alert you remotely with the separate purchase of the PHCC Pro Series Connect WiFi Module. With a 3 year warranty, it's easy to see why we recommend this product. Just don't forget the batteries. This system requires 1 or 2, 100 Amp Hour or greater batteries. This is usually going to be a Group 27 or Group 31 Deep-Cycle Marine AGM or Wet Cell Battery.

    Best Smart Sump Pump

    Expert Review
    The Liberty Pumps 442-25A-EYE Battery Backup Sump Pump System is new and not your ordinary backup system. For a small pump, this baby packs some punch and that's why it receives our recommendation. It provides plenty of power to drain your sump pit up to 7.5 continuous hours. Since your pump starts and stops, it can actually back up your pit even longer. Best of all, this kit will handle a maximum 21 feet of head on DC power and a pumping capacity of 1800GPH @ 10 feet on DC power and 2100GPH on AC power. This 442 system includes a heavy-duty fan cooled 25 amp charger that can run as a continuous power supply for the backup pump in the event of a main pump failure. The dual battery box accommodates (2) Group 27 or 31 batteries and will work with wet cell, AGM or gel-type batteries. The cloud-based, no fee NightEye® App alerts you to backup pump notification, high water level alarm, AC power loss & Blow fuse / DC pump issue in addition to also providing 12V battery charge levels and critically low battery warning. Set-up is very easy between App and alarm with BlinkUp technology The advanced notifications will alert you via text, email or push notification to up to 4 different contacts/phone #'s. It will alert you of "Low Basement Temperature" (User defined temp. setting), and also provides loss of WiFi notification just in case the connection is lost. Taking these things into consideration, you can clearly see why we really like this system.

    Best Combination Sump Pump

    Learn More About Pro Series PS-C33
    Expert Review
    If the Basement Watchdog 1/2HP model BW4000, or some of the smaller combination systems that we offer doesn't quite make the cut for you as far as pumping capacity, this system will fill the void. The primary pump offers a very capable 3000GPH and the battery backup pump will handle 2400GPH at a 10-foot head. Not bad for a system at this attractive price! Besides the Pro Series' exclusive monitoring system that "watches" over the battery functions and detects irregularities, it pinpoints problems and sounds alarms as needed, this system also includes their own pump controller model DFC1 with caged dual float switch, for redundancy and extra added protection. This system is designed to operate with one or two Basement Watchdog model 30HDC140S batteries and will operate the 12-volt pump for up to 7 hours continuous with a single battery or 24-36 hours non-continuous. You can double those run times with a second battery if you choose. I'm giving this system our recommendation rating because it's a great contractor grade system and it also includes a 3-year warranty.
