terrible design
I have the earlier version of this sump pump. There are three 1/8 inch bolts that hold the pump together and to the base. Duh this item is made to pump water and the base is always covered in water since the float cuts the pump off when the base is still submerged. The bolts are not stainless steel and they rusted to the point that when I lifted the pump it fell apart and all the oil leaked out. Only owned the pump for a little more than 3 years, just enough time for the warranty to expire. Not going to bother to try to rebuild it as the parts and aggravation are not worth it. Beware of this poorly designed product.

    This pump is so quiet you have to look at the float position to see if it is on. Installation was EZ.

    easy install and actually a fun project
    This install was a fun little project. Previous pump started getting stuck on and cleaning it out didn't fix the issue. I thought I could reuse the PVC out of the old one, but it was stuck on pretty good, so I bought new PVC and cured it together no problem then just screwed it into the new pump. Dropped it down and made sure it was level, reconnected all the pipes then it was plug and play game on. This thing is twice as big as my previous one but HALF AS LOUD (aka this is quieter), so that's nice. Seems to be good to go now, on autopilot. (Before installing the new pump I cleaned out the pit of as much sediment as possible.)

      I am very satisfied with the performance of this brand. I purchased this as a backup because I need reliability to discharge 24/7 year - round. This unit has performed flawlessly and has a fair price and a good warranty.

      Super quiet pump! No weep hole needed! ONE FLAW!!
      The only complaint is that the power cord is too short! My outlet was in the ceiling and the old pump reached fine. I have a Zoeller pump on the other side of my basement and that power cord is a couple feet longer and reaches the ceiling outlet. I had to relocate the pump outlet and drop it lower with a piece of wood. See image. For that reason, I had to knock off a star!

        Initial product review. I will try to remember to update later, if needed. I installed the sump pump on 1.25.20 to replace a Flotec (FP0S2450A) 1/3 HP sump pump. The Flotec lasted 15 years, so I got more than my monies worth out of it. Installation was easy and straight forward with no gotchas. The unit is very robust and feels really solid compared to the Flotec and the handle is very handy to aid installation. To test the pump, I drained the water heater discharge water into the sump basin (over 100 gallons) and if I did not see the pump actually working, I would have thought the pump was defective...this pump is crazy quiet. I did notice there is only 1 power cable vs 2 cables on the old unit. The Flotec set the bar very high, but I hope the Ridgid last at least 10 years.

          This sump pump was very easy to install. It runs very, very quietly. I do not hear it running any longer throughout the day like I did with my old one. It looks like it will be much easier to keep clean compared to my old one as well. How long it lasts remains to be seen, but at least there is a 5 year warranty. Highly recommend this product.

          Previously had this same sump pump over 10 years. She finally died before I bought the same one. Was reliable during the time it worked. Pumps out water fast, quietly and efficiently. I highly recommend
