CUSTOMER REVIEWS

Rated 2.9 out of 5 by 51 reviewers.
Rated 1 out of 5 by Bad product The weak part of the product was the outside thin supporting bar. It is easy to broken due to the rust under the water. You will not detect the issue until your basement is flooded. March 11, 2014
Rated 1 out of 5 by Cheap parts This pump looks great for the price until you open the box and install it. The float is of concern, because there is a rubber guide for the float rod. This part is of big concern, because it comes loose easily. October 21, 2014
Rated 4 out of 5 by Good pump, switch easy to fix First, the pump itself...is fine. It is very reliable and quiet in operation. The switch can be problematic as they sometimes stay stuck in the "on" position and as a result, the pump runs continuously and can fail. These pumps are made by Wayne. Either Ridgid or Wayne should revise this switch. My switch failed after two years. Here's how to fix: 1. Remove switch from pump. 2. Remove screws from switch housing. 3. Remove cover. 4. Press on diaphragm to confirm switch is not seized. You should hear it "click" when you press it (switch is "on"), it should "click" again when you let go it (switch is "off). 5. Carefully remove diaphragm. Clean diaphragm and switch housing. 6. If diaphragm is distorted, use a hairdryer to restore to original shape. 7. Using clear silicone caulk, apply sealant to the surface where the diaphragm seats in switch housing. 8. Re-insert diaphragm. Make sure the diaphragm is not concave, and that there is a pocket of air between the diaphragm and inner "click" switch (from step 4). This air pocket is what makes the diaphragm work. It is this loss of air that causes them to fail! 9. Next, apply a "face bead" of silicone to where the rubber diaphragm meets the plastic housing on the outside. This will prevent water and sediment from getting between the diaphragm and "click" switch. Do NOT press the diaphragm or reinstall switch to pump until silicone caulk is completely dried. 10. Once dry, reinstall and enjoy your properly functioning pump. If you just bought it and have not installed it yet, I would recommend doing this procedure first!! Otherwise, make the repair before failure. You'll thank yourself. January 4, 2014
Rated 5 out of 5 by Replacement sump pump! We needed to replace our ejection pit sump pump and this is the best value for that use October 14, 2014
Rated 1 out of 5 by Switch design flaw The switch is the weakest link on this pump. My old sump pump lasted nearly 15 years before it went out. Bought this pump to replace it. The new pump failed in less than 3 months, which caused flooding in my crawl space. The "diaphragm" switch appears to be defective by design. When I plugged the motor in without the switch, it was completely dead. I'm guessing the switch got stuck in the "ON" position, causing the motor to run continuously until it burned out. Fortunately the pump was under warranty and Home Depot offered an exchange. I do not recommend this pump at all, or any other brand of pump that uses a diaphragm switch. Buy something like a Zoeller or Flotec. The only good thing about this pump was that it was very quiet. November 27, 2011
