Which is the best back up system for this pump ?

Asked by: Anonymous
Depends on how much room you have in your sump pump basin - I am looking a a couple of models from Basement Watchdog. If you have a generator on your home for power outages and you only need intermittent battery back up support until you can hook up the generator then you may not need as robust a system. Cost will vary depending on the features, pumping capacity and potential length of time needed for battery backup.

Customer Reviews

1/2 HP Submersible Sump Pump with Vertical Float Switch is rated 3.0 out of 5 by 155.
Rated 2 out of 5 by from 3 of these pumps in 4 years..... When I decided to to put in a Watchdog back up sump pump 4 years ago I decided to change out my original sump pump that had been working just short of 20 years(yes, 20 years). I figured I had gotten my money's worth out of it and was due for it to quit at any moment and why not change it out while I'm re-piping for the WatchDog. The first Ridgid lasted just 18 months, but with their warranty they just swapped it out for a new one. No big deal right? Well the next lasted 2 1/2 years and this time it took a little convincing for them to honor their warranty because they didn't do any paperwork on the first exchange. But they did and I appreciate it and their customer service gets an A+ for that. So the good about the sump pump - it installs easy, is quiet, has the power to do the job, and if you like to change out the pump every few years the warranty is good(note that the the original lifetime warranty is now 3 years). The bad - a sump pump of this price should not have to be replaced every few years. The first pump just stopped working and the second pump the switch went bad. If you do buy this sump pump get the WatchDog Back-Up with it - the second time this pump went bad I was on a 10 day vacation and the WatchDog did its job perfectly.

Rated 1 out of 5 by from Bottom line: don't let this pump get wet The switch initially failed to close after about 18 months; I managed to get it working again; and the switch failed again after another 18 months. I installed a simple tethered float switch to hopefully last through the Northwest's rainy season so I can replace the whole thing with something more trustworthy. Many of its parts have substantial rust, so it might not last that long. To the pump's credit, it ran continuously for 12+ hours to pump out the water it had let in, twice. But I expect a more reliable overall unit when it costs as much as it does. I can't imagine how this pump could be better than cheaper options.

Rated 2 out of 5 by from Something that's made to spend it's life SUBMERGED IN WATER....... Should NEVER rust! After about 4 years it died.. Not the motor, not the switch but the metal rods that connect the whole thing rusted through and it came apart. I'll be looking elsewhere for the replacement. Unacceptable cheap engineering on this model. Any machine is only as good as its weakest link.

Rated 1 out of 5 by from Failed after 2.5 years Heard a noise in the basement and went down to find the sump pump running with no water in the pit. I unplugged it and unbolted the pit cover. When I removed the pump I noticed the float in the bottom of the pit. I went back to Home Depot and looked at how it was supposed to work and discovered the float goes up and down on a steel rod. The bottom of the rod has a small ball on it to hold it in a rubber flap. The rod being steel and living in water rusted. the bottom portion was missing. This all could have been avoided by using stainless steel or something that don't rust. Fortunately I had saved my receipt and Home Depot exchanged it no questions. Seems like several others have had the same problem. I paid a little more to get the Rigid name and now I have to wonder why??

Rated 2 out of 5 by from Rusting Sump Pump Parts - seriously? The Rigid SP-500 worked for 3 yrs before the bolts that secured the base to the top eroded. This caused the pump to run continuously, not able to create suction to remove water. Timing of the failure during hurricane Sandy made for anxious days until it could be replaced.

Rated 2 out of 5 by from Rusty components I had this pump for about 3.5 years. The pump worked great until the guide wire for the floater rusted out after less than a year and allowed the floater to get stuck causing a flooded basement. I replaced the wire with one I made using a rust resistant material from a local hardware store. That worked well but then the long screws that hold the pump together rusted out and the top part of the pump separated destroying it and resulting in another flooded basement. The pump works well but it's puzzling why a submersible pump would have critical components made out of rust susceptible materials. Rust resistant screws and wire can't possibly be that much more expensive to use.

Rated 5 out of 5 by from This pump has worked great for me :) I have had this pump for about 3 years. It has worked great for me. I just installed a flood sensor in my sump pit in case the power goes out, or the pump breaks. Then I decided to go onto Home Depot's website to buy another one of these pumps to have as a backup and seen all of these bad reviews :( I called Ridgid and asked them what is going on with these pumps. The guy was real professional and nice to deal with. He explained to me the reason why so many people have had the switch go out is because they did not install a check valve, or waited to long to change out the switch like it says to do in the manual (every 2 years). I took the time to install mine right in stead of using the geturdone method most people seem to be using these days. I plan on buying another one of these pumps for backup, despite all of the bad reviews because in my experience Ridgid makes quality products and they stand behind them ;)

Rated 1 out of 5 by from Don't Buy One I've had to replace this RIDGID sump pump 3 times in the last 4 years. 1st one lasted just over a year, the 2nd one didn't even work after I installed it (took it back), this one just over a year and it broke! I switched over to a Flotec from Home Depot on 1/02/12. Am HOPING this Flotec will last at least 4 to 5 years! It seems like the switch in the Ridgid stops working, if you tap it with a hammer it will start to work again. How long, your guess is as good as mine. Could be for 1 or 2 days or weeks. So before replace it tap the head a few times to see if it starts worrking again. My next job is to see if I can find replacement switches for to 2 Ridgid pumps I have. Just so you know Ridgid warranty DOES NOT cover any moving parts! That leaves only the housing! lol
