Rated 3.1 out of 5 by 18 reviewers.
Rated 1.0 out of 5.0 by Lifetime Warranty excludes "wear and tear" after only a few years. We paid extra ($319 on 9/12/2010) for this because of the "Lifetime Warranty." We never expected that just four years later it would fail completely, and the company would leave us out in the cold. I will never buy a RIDGID product again, nor will my six adult kids, and we'll swear them off for the grandkids too when they come along. A company that won't stand by its warranty needs to be avoided. Period. Time to head to a real plumbing supply house for a reliable brand. October 21, 2014
Rated 1.0 out of 5.0 by Not Impressed Lifetime warranty shuold last longer than four years. September 11, 2014
Rated 1.0 out of 5.0 by DO NOT BUY THIS PUMP IT'S JUNK I paid $200 for this pump 4 years ago and it has already failed. Pump motor is seized. Warranty is for only 3 years. This is the second time my basement has flooded with sewage because of these cheap Rigid pump failures. I've learned my lesson. Purchased top of the line Flotec pump. Much better constructed cast iron pump and better warranty - 5 years. I wouldn't wish this nasty job on anyone and hope to never have to go through it ever again. December 7, 2011
Rated 4.0 out of 5.0 by Pump Replacing a under a year old pump from compeditor . This one cycles more completely and less often. Double cord design requires lid modifcation for gas seal. Best warranty offered anywhere... April 12, 2007
Rated 1.0 out of 5.0 by Pump seized up I only had this pump for 4 years and it no longer works.This pump only has a 3 year warranty. Paying over $200.00 I would think it should last longer. I'm now going with a different brand that has a lifetime warranty for only a few more dollars. Don't waste your money on this pump. July 13, 2014
