Wayne WSSM30V Reviews
Strobe made the following comment on February 2018. This Install Was Surprisingly Simple And Took Me No Time At All.
I have never done plumbing work or any sump stuff before. I bought a 5-foot section of 1.5-inch PVC, pvc cement primer, and pvc cement at the local hardware store. I used a jigsaw (only thing I had) and cut the pipe so it would come up to the 90 degree bend over my pit. I primed and cemented the pipe into the Y fitting and let it sit for 30 minutes to set. Cut my old pump out, dropped this one in, and used a 4-inch long rubber fitting with screw clamps on each side of it to join to my existing pipe. Sure beats the nearly $1500 quote I received to have a contractor put in a battery backup combo system. And it was not difficult to install since it is pre-assembled!
Oval had this to say on November 2016. WAYNE Was One Of The Most Highly Regarded Brands Online.
After 18 years of running, I decided it was time for a new one. And since the battery backup didn't work, it was time for one of those too. I checked online before buying. This was not a time to skimp on quality when the future of my basement is concerned! I dropped the pump in the sump, plugged it in, and poured water down the hole. Powered pump worked flawlessly and was QUIET. Now if the power goes out, I have about 10 days worth of sump drainage because I hooked up two batteries! Highly recommend this pump. Make sure you get a DEEP CYCLE MARINE battery. I checked with Wayne about installing two batteries; they told me it was not tested for such an installation and a problem of over charging may occur. I bought a Battery Tender Deltran Battery Tender (021-0128) 1.25 Amp Battery Charger to it so it keeps them charged and never over-charges them.
SMA writes on April 2018. Recommend 100%
Purchased the WSSM30V last year, but did not feel the need to write a review until we lost power for 2+ days recently. The pump worked perfectly, our basement stayed dry (our neighbors did not).
When power is out, there is an audible alarm. Not quiet, but not blaring either. You can hear it from one floor away. During operation, the pump is very quiet.
Zoeller 508-0006 Reviews
David writes on March 2018. The All In One 508-0006 Unit Makes Sense
My Zoeller pump was eight years old and it was time to replace it. The all in one unit made sense as the back-up unit was much better than the existing one in the well. I hired the installation through Amazon and it went well. One word of caution: Make sure you know the width of the bottom part of the basin. Many times they taper so even though the top diameter may be 18-inches the bottom may only be 16-1/2-inches. For my basin, it is a tight fit in the well due the increased size of the back-up unit.
Tim states on March 2018 Very Good Product This Combo 508-0006
What an awesome product. Everything was boxed neatly, and all parts were with it. Very easy to hook up / assemble. Everything went together as stated and pump worked perfectly. I used the VMAX battery 125 amp and everything is working great.
Ismael provided this review on October 2015 The Combo Zoeller Easy As Pie
Set up was simple. The digital read out gives all vital information. Takes the guessing out if a new battery is needed. I am happy with it.
Wayne WSSM20V Reviews
Roy indicates on September 2017 Awesome
It took 30 minutes to install and get everything the way I wanted it and all I had to purchase was a little piece of extension pipe to go into the WSSM20V and connect to my existing outlet pipe. The entire thing was assembled and ready to go right out of the box and the battery that came separately was fully charged and also ready to go. You really do not need instructions to hook this up. I filled the pit and bam, it sucked the water out instantly.
David states on May 2017 Excellent
While I have been fortunate to never lose power, when I saw the sump pit filling quickly, and the pump cycling every 20 to 25 seconds, I realized that if I did lose power I would never restore it quickly enough to prevent the pit from overrunning. Also, the same problem would occur if I was not at home and the power failed. After research I settled on this system, and couldn't be happier. The install was simple, and both pumps work just as claimed, while also being very quiet. Hopefully I'll never need the backup pump, but have the peace of mind knowing it is there.
Zoeller 507-0008 Reviews
Robert indicates on December 2017 Get A Battery Backup Pump For The Primary Pump
The Zoeller 507-0005 worked great the one time I needed it from several months ago when the electricity went out, I just wished I had it when my basement flooded before that! Because of electricity outage. I like the Primary Backup Pump Combination.
Tom says on April 2018 Five Stars
I have had the Zoeller 507-0008 for several years and it works great. I was easy to install. I made sure I had an eighteen-inch diameter pit before I bought it because the system needs that much room since the bottom of my basin tapers a little bit.
Rob says on August 2017 Awesome Sump
Everything was as described and very easy to assemble. Looks very dependable and well made.
PS-C22 PHCC Reviews
Bob stated the following on February 2018 Easy To Install And Peace Of Mind
The PS-C22 was easy to install in my existing 24"x30" sump basin with plenty of room and the directions were easy to follow.
Victor left the following on October 2017 Very Good Pumps For The Price
I just installed this system. This replaced an old one in the house that was about to die. We had our plumber install it and Its been working well since.

Pentair Water Combination-Sump-Pumps
Pentair Water (Flotec-Pumps) has two combo pump systems: FPCC3320 and FPCC5030. The combo systems with the lowest pump-performance is the FPCC3320 with the primary sump pump FPZS33V with 1/3 HP, vertical float switch, 2,400 GPH at 10-foot, thermoplastic base, zinc housing, bottom suction screen, 1-1/4-inch or 1-1/2 inch discharge, and the battery backup PS17-118 with reed float, 600 GPH.

The FPCC5030 includes the primary sump-pump FPZS33V with 1/3 HP, thermoplastic base, zinc housing, 3,000 GPH, vertical float switch, bottom suction screen, 1-1/4-inch or 1-1/2 inch discharge, and the backup-pump PS17-2005 with thermoplastic housing, reed float switch and a 2,000 GPH, The system requires a 14-inch diameter basin and has a 2 year warranty and can contact a cell phone or computer via Link2O.
Measure the basin top diameter and notice if the basin narrows toward the bottom. Most 18-inch diameter pits narrow gradually toward the bottom which is generally around 16.75 inches wide.
Note the basin size required for the system per the manufacturer documentation.
Know the GPH required to handle the water volume coming into the pit during a heavy rainstorm. If the GPH required is unknown, identify the distance between the ON and OFF point of the float switch. (The manufacturer will include this info in their specifications.) Count how many times the pump runs in 60 seconds (1 minute) during heavy rain. If your basin diameter is 18-inches, 1 inch equals one gallon. If your basin diameter is 24-inches, 1 inch equals two gallon. Multiple the number of inches between the ON and OFF point times number of times the pump runs in 60 minutes times one. For example, if the distance between the ON and OFF is 5 inches and the sump-pump runs 5 times during 1 minute and the basin in 18-inches the primary-pump GPH required is 25 GPM or 1,500 GPH.
Decide the GPH desired by the battery backup. Only a few backup-pumps with a combo system are close to the GPH of the primary pump. The Liberty Pumps using the 442 backup-pump are very similar to their primary sump pump.
Decide the importance of a warranty. Wayne has the longest warranty. Flotec has the shortest. Most pump manufacturers offer a 3-year warranty.
