Liberty Pumps 280 - 1/2 HP Cast Iron Submersible Sump/Effluent Pump (Non-Automatic)

Powerful and super quiet!

I've not yet installed my two 280 manual pumps but already have experience with them switched as both vertical magnetic float and wide angle floats. These are solid American made pumps that have served me very reliably. The small footprint of these manual pumps coupled now with an electronic levelguard switch will allow me to mount two at the 14" dia base of my sump well and plumb them each in parallel with spring enabled silent check valves that then route to a 2" line that exits the basement.

Further coupling this redundant system with a whole-house auto-on generator will give me peace of mind that I've never had with the inadequate battery backups. I have a deep basement embedded in bedrock that is only 5' below exterior grade. The result can be 25+ GPM flows through my sump when ground is saturated and follows the rock to my basement drainage. Great pumps that fit and give me confidence.

This pump was purchased to replace a popular over-priced box store brand which was corroding after only 6 years. The cheap float switch failed on my old pump. The Liberty pump has a very heavy duty housing and empties my sump pit in about 8 seconds. The pump is very quiet. Although it uses a little more electricity than a 1/3 hp pump it runs for shorter periods of time due to the higher volume of water it can evacuate. I am using a Level Guard sensor switch (I highly recommend). The Level Guard should last about 10x longer than a float switch. One minor complaint is that the threads on the discharge need to be cleaned out with a rotary wire brush and pick prior to screwing in the male PVC fitting. Otherwise the fitting won't completely screw in and seat flush. I think this should have been done during production. I was considering a Zoeller however the Liberty seems to be a more efficient up- to- date design. Time will tell but ... so far so good. I will update my review if anything changes.

This pump is solid and heavy. I like its taller and thinner so it was a great fit for my pit with a separate backup. Would recommend this to anyone.

I upgraded from a HydroMatic 1/4 HP to this 1/2 HP Liberty Pump. This pump is heavy and extremely quiet. After installing the controller, I was adding water to my sump well to adjust the pump ON time. While waiting for the pump to turn on and still adding water, the water level started to drop rapidly. I didn't even hear the pump kick on and that was the purpose of adding water to the well. So, I had to try again. This time I held onto the pipe to "feel" when the pump kicked on.

As for the Pro Series Controller, I gave it a "4" because of the crappy battery cover and the volume of the built-in alarm. It's very quiet and even in emergency mode, it only chirps a low chirp occasionally.

I added the Watchdog alarm, which is extremely loud, to the remote switch on the controller and it works well. The controller, however, doesn't turn the remote alarm ON unless there's an emergency alarm. The low battery and missing sensor chirps are only audible from the controller itself. The sensing probe on the Watchdog alarm works instantaneously. I will be placing the probe on the floor and running it in parallel with the remote output on the controller. Pretty sweet setup for the price. Highly recommended.

I am extremely pleased with my new Liberty 280 pump. This pump is by far rated at the highest head of any in it's class. It pumps down my sump in 2 - 3 minutes, compared to 10 -15 minutes for the pump it replaced. Anyone who needs the extra discharge pressure will be very pleased with this pump.

Purchased this pump a couple weeks ago, it shipped promptly, however the shipping company broke the pump in transit, oil leaked all over the box, rather than send it back, the shipping company placed it in another box and relabeled it, and left it on my porch.

Immediately I was in contact with SPD, Joan and Robert were both very helpful. Within a couple hours a pickup had been scheduled for the old unit, and the new unit was cross shipped as soon as the old unit was picked up at no cost to me.

The new unit was fine, and was installed this past weekend. This pump moves some water, and is very quiet, much more quiet than the 30 yr old pump it replaced. Thanks SPD!!

I installed this valve with my new pump. I was impressed that the "flapper" inside was metal reinforced. The others I've seen are either rubber or plastic. The Zoeller seems more robust. The somewhat larger chamber inside the valve body provides quiet operation in my experience. A cheap check valve is just that....a foolish place to save money. Failure of this part could create a messy expensive situation. I have great confidence in this product.
