Answer: 
When I bought mine in December 2008, the warrant was lifetime. Home Depot confirms this. If/when the pump dies, bring it in for a similar replacement.

Answer: 
Kathleen - Ridgid states it will do 75gpm at 10 feet TDH. They do not have a complete TDH/GPM pump curve listed, so you may have to "guesstimate". If you are pumping out an open ended pipe, your most significant head loss is in the amount of lift you are trying to achieve. If the discharge pipe or forcemain is over 20' long or smaller than 1.5" diameter, you may also need to calculate some significant Read More

Answer: 
First - Unplug the pump & verify you have power at the plug for the pump.
Second - Disconnect the pump discharge pipe at the lowest possible elevation where you can direct the flow back into the tank or basin.
Third - Plug the pump back in and start it by manipulating the on/off float or turning it on manually. If it flows fast and steady, reconnect. If it doesn't flow at all, disconnect from the power

First - Unplug the pump & verify you have power at the plug for the pump.
Second - Disconnect the pump discharge pipe at the lowest possible elevation where you can direct the flow back into the tank or basin.
Third - Plug the pump back in and start it by manipulating the on/off float or turning it on manually. If it flows fast and steady, reconnect. If it doesn't flow at all, disconnect from the power again and check the impellor to see if its bound up by debri. If the impellor will spin easily, but the pump still doesn't discharge water, it may be the pump. If it ran water when disconnected, but still doesn't run when connected, you could have a bad check valve upstream or the pump can't discharge against the head (back pressure) on it. Consult a plumber, pump service company, or engineer at that point.
Hope that helps. Read Less

A previous question asked what type of oil is appropriate for this pump. A response said that the oil used in the pumps is dielectric or transformer oil. Does this pump need to have oil added to it?

1/2 HP Submersible Sewage Pump is rated 3.4 out of 5 by 23.
Rated 5 out of 5 by from The pump was a replacement for the same one that lasted 10 years before the rubber/plastic inside... The pump was a replacement for the same one that lasted 10 years before the rubber/plastic inside decayed away, hopefully this will also last that long. Product is lightweight and functions better than sump pump.

Rated 1 out of 5 by from 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.

Rated 1 out of 5 by from 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.

Rated 5 out of 5 by from Great Clear Water Pump Great pump for use as a basement sump pump. Just retired it today after 11+ years of regular and heavy use. Still worked, but a switch became somewhat unreliable, so decided to pull it instead of risking total failure.

Rated 4 out of 5 by from 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...

Rated 1 out of 5 by from Crapped out after 18 months Crapped out after 18 months". This pump is not worth it's weight to what it supposed to pump. It literally stopped working after 18 months pumping effluent fluid. I am going to see if I can return it to get fixed and have it as a back up when then the new pump fails in the future.

Rated 1 out of 5 by from 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.

Rated 4 out of 5 by from Warranty We purchased this pump about 6 years ago to service a lower level bathroom and bar drain that is used only occasionally. It quit working during the recent holidays. It just hummed, but would not engage. The float switch was not the problem. We called our local Home Depot, we were told to cut the cord off the pump, bring just the cord in and we would receive a new pump. The lifetime warranty worked great at the store, no need to send anywhere for warranty service! It cost us nothing. We even got a new receipt with the replacement date, also showing the new (higher) price for any future warranty problems. The warranty on this pump is great.
