Pump mechanism does NOT last long...would NOT recommend
356978
This item is a POS- only lasted 2.5 weeks.  I was bamboozled by all of the 'positive' reviews here, in the end I'm stuck with a POS soap dispenser that has a poorly designed pump mechanism that no longer works!!!

I've had this pump for about 2 months but have seldomly used it. After about the 5th or 6th use (first set of batteries still run the motor with power and hardly used the car adapter) the cam on the motor wore completely down due to friction. The cam and diaphragm drive arm should be made with better materials like Teflon or something that doesn't wear so easily. I would've paid an extra buck or two just to have this part not wear so quickly. Previous reviewer had the same problem. I will not recommend buying this pump for this reason and question the reliability of the rest of their line of aerators. Look elsewhere unless changes are made to improve the design with better and longer lasting materials.

This pump regularly runs 250-350 Dollar great price however mine only lasted 7 months. Would not recommend buying this item.

This is a product review. The pump only worked for 1 month before it died. I was using it indoors. It was just pumping water 3 feet up my aquaponics system. Save your money and buy a better quality pump.

I am reserving the right to change this rating if the seller has a favorable return policy.

I liked this pump while it lasted, but after a season and a half of light use it seems to be finished and just can't build pressure.  It was definitely not worth the money.

I bought 3 of these in February - it's now May and all of the "pump" action is gone.  When you press the top down it just stays there.  Would not purchase again.

I purchased this pump and it worked great for the first couple days but now its barely going, what is the warranty policy? Really just want one that works correctly. Please contact me with what steps I should take moving forward, only had pump for 23 days stopped working correctly after the first week.

I usually don't write reviews but in this case since this is my third attempt to use this pump I feel compelled to write. The first pump lasted about 1 month and worked very well.  And then the problems started.  The hose connection on the "plastic pump" completely snapped off from the unit while I was connecting the hose and the second pump while I was disconnecting the hose all (by hand). Amazon has been great and has replaced the first two and now after just one (1) use on the third pump the assembly have fallen apart.. see attached picture.. Although the pump removes water out of the pool cover when it's not falling apart , I would NOT recommend it to a friend. It's all plastic and not well made !!

Disappointing. .. After only 1 year and limited use the pump failed.  Plunger head goes down but sticks ...You have to manually return it to the up position.  Simple design, the piston has a rubber o-ring which sticks against the main cylinder wall.  I reworked the tip on the piston to allow it to function but for this amount of money I expect better. ...much better.  Sorry but I have to give you a 2 out of 10 for a grade.  If you'reconsidering...keep looking, you're wasting your money with this product.

Running for less than a month as a return pump for my nano set up (13.3 display, 10g sump, approx 2 foot of straight vertical piping with a ball valve for fine tuning) then after turning off and on off, it started making a grinding noise, turned it from pump to feed mode and then back to pump mode, and since, it has stopped working completely. Very disappointing as all my piping is dependent on this pump...while the controls light up as they should, the pump will not rev up/spin at all...tried all connections and it all looks fine.  Upsetting that this pump would fail after 3 weeks of use :-/

Thought this was a winner until I used it a half dozen times.  The suction became intermittent and then quit completely.
The motor is fine, the pump gave out (bypass valve failed).  Called customer service and they sent a repair kit at no cost, of course I had to install it myself.  Tested OK but after a couple of uses popped and then quit again.  Also the supplied hose is huge in diameter and hard to use.  Discarded it in the trash right away and used a regular size hose.  Now the rest of it is going into the trash as well.  Spend a little more and buy something that will last a while.

The pump quickly moves the liquid out of my grinder pit.  It is louder both in starting/stopping and when running than my old pump, which was a Zoeller, but it is also much more powerful.  I decided to get the bigger pump in hope that it lasts longer than the 11.5 years I got out of the old one.

Update 4/1/17:  This pump failed today, less than 2 years after installation.  So much for getting a bigger unit in hopes it would last longer.  No more Liberty pumps for me.  Probably back to Zoeller.

We bought this pump to pump out our pool cover that collects rain so it's not used all that often.  Checked my Amazon records and it shipped October 31, 2011.  It's now February 11, 2012 and it has quit working.  Would not recommend.

Emailed the company and received an immediate response to call so that a service rep could work with me.  Brought the pump in the kitchen and lo and behold, the pump is working.  Was impressed by the response to my email.

The cats greatly enjoy this fountain, however the pump seems to have stopped working completely after only a few months of use. I have tried to eliminate any hair that is clogging the pump, but to no avail. This seems like a flawed design for a pet fountain. I would recommend looking elsewhere when  it comes to pet fountains. I like the price and the product originally, but now its' basically unusable because of the pump on it.

This is the second attempt of this particular model of DeLonghi espresso maker. In both situations, within 6 to 8 months the pump seems to go bad and doesn't push water through the coffee anymore. I won't be buying another one.

We have gone through 3 of these pumps in 3 years.  Each year we have to call them and get a warranty replacement because it stops working after one year.  The company has honored their warranty (because I call before the year is up) but it gets annoying after awhile.  You are better off purchasing a better item and not worry about whether or not it is going to work from year to year.

I'm getting a different brand pump this year - I'm calling it quits.

I have only had this for a few months and now it is no longer working. I also noticed a hairline crack under the porcelain tank, which I am not to happy about. The pump is really weak, and stopped working only a few weeks after getting it. I usually have it on for maybe 5 hours a day. Now, I had to take it off my desk at work since its embarrassing to have a broken product for all to see.
