Question: My sump pit is 18" in Dia,, pump runs 4 seconds ON, 40 seconds OFF what's your experience with cycle time ? or opinion ?
Document: Just installed the Liberty 257 sump pump in a 16" diameter sump pit with plenty of room to spare. I love the compact design with unobtrusive vertical float. I had a major concern when, during installation, I discovered I have a 1 1/4 inch discharge pipe, not the required (per instructions) 1 1/2 diameter. I called Liberty technical support twice, and was told each time a 1 1/4 diameter discharge should be fine for this 1/3 HP pump.All in all, I think the Liberty 257 is just as good, if not better, as the major competitor's green one, mostly because of the ingenious compact magnetic vertical float that the other one doesn't have.
Just installed this to replace a Zoeller M53 that was in service since 2003. I was planning to replace my sump pump with another Zoeller but the M57 was not available at the time of order and I liked the compact float design on this pump. Since I was also planning to install a Wayne EPS25 battery back-up sump pump, I wanted confirm the dimensions of both pumps inside my 18" diameter sump pit before buying anything. Zoeller did not include pump dimensions on their product specs or online manual but Liberty did.
In order for it to work I had to unplug it, then plug it back in, the thing would then pump the water out, but as the sump began to fill with ground water it would not cycle back through but just pump at about 1/4 it's normal rate, until I unplugged the cord and then plugged it back in. This thing is terrible. I would not recommend it to anyone that has a sump in their basement that fills with a descent amount of ground water.
I had 3 year old Zoller sump pump (green color stuff) in the sump pit. The switch started to get stuck on ON position and it continued to run without having water to pump out. I would say this that Zoller pump ran for very long time without water. I decided to replace it but not with same product. I decided to go with Liberty pumps based on other people reviews. I made a good decision. Libertry pump is great. I must say that this is the quitest pump I have ever listened to.
I asked how everyone liked this pump 4 days ago. Got good responses and ordered. Received it today 5/16/14. Very fast delivery. We had 6 inches of rain last night and my old cheap sump pump was running overtime. It was very loud and worked half the time. I had this one switched out and working within 7 min. That is no lie. Delivery. An dropped it off at about 6pm and by 6:15 I was eating dinner. I already had everything cut. This is a very solid unit.
Our 140 year-old house is nestled in a bowl of clay. Every spring, it's sump pump palooza. I have 1 in the house and another in a pit that gets all of the water from the French drains. That 2nd one goes through a period of about 3 weeks of running every 20 seconds. It would take about an hour for the basement to flood without that pump.Recently, the outside unit failed, but it failed safe - i.e. it failed &#34;on&#34;.
I did not want to remove my old pump just to take measurements and I figured a company that posts technical drawings and flow rates online for easy comparison gets my vote of confidence. Plus with all the positive reviews I figured I would give Liberty a try. The pump works great and quicky drops the water level from 7 inches to about 3 inches within 4 seconds with a head of about 9 feet. I did follow the instructions to drill a 1/8" drain hole about 3 inches from the discharge port even though the pump already came with a drain hole at its base.
This pump is well constructed and runs very quietly,,, I selected this pump because the top selling pump seems to have float switch problems,, and this pump did not have and of those problems, at least in the reviews I saw.Time will tell, but so far , so good.
I bought this to replace the builder installed unit in our house. Like everyone else has said, it is a solidly built, quiet pump which should last a long time. I only wish it had a longer run cycle. Definitely heads & shoulders above anything available at H@me Dep@t or Men@rds. They recommend an inline check valve which I installed. The Liberty 253 is the same pump  with a different float switch that will drain 6.5 inches of water per cycle, vs the 3.5 inches per cycle of this unit.
In addition, the green one requires a minimum 18 inch diameter pit, whereas the Liberty as small as 11 inches. The build quality is certainly equivalent.
Answer: yes
