inti gomez: I just got two zoeller pumps with battery back up for $1,800...hope they work ...
mhaddadi: WHat is the minimum water level required for pump to start.?
NOpcBS: It seems that there are NO high quality and reliable sump pumps these days. Zoellers have mechanical switch issues FAR too often...and there seem to be no reliable and long lasting dual switches to use with their floatless pumps either. A market someone could take charge of if they'd simply create a complete and high quality pump system!
dan craver: Zoeller pumps are notorious for switch problems. I wouldn't have one for free.
carl engel: I'm on my fourth pump in 10 years
offplanetevent: Rotten apple. useless video.
Frosty Hengewadder: This video is dumb, try making a video of you actually installing one not talking for 7 minutes
femtoman2357: Thanks for the tip about the weep hole in the body of the pump. This insures that the impeller always has prime and the pump will not airlock. For this reason I did not drill a hole in the outlet pipe and my pump has never airlocked. Again, thanks for the tip and thank you Zoeller!
Tom D: Maybe I misread the install instructions on my M98 pump. It said when using a unicheck is installed. Not sure what a Unicheck is. (Check Valve maybe?) a 3/16 dia hole in the discharge line even with the top of the pump. I am thinking this is for air to escape. If the float switch goes bad cant you just use another switch that goes on and off and the pump can plug into that switch?
Junior Garcia: you just put the pump on the ground or you need to drill screws so the sump pump wont go wondering?
Junior Garcia: does a ump pump not being use should be no water in it? i open the lid and i see my sump pump flooded with water.
Sylvain Mainville: Liberty 280 for me.
Pro1er: I have t agree with others here, this pump is a turd. The switch is way under specced for the pump and will burn out in a few years. Also, the short throw of the float causes the pump to cycle more than necessary, putting even more stress on the switch. Even Zoeller says that the switch should be replaced every year. Huh?
Read the reviews on Amazon, then go and buy a quality product.
Derek Y: Can you replace the float switches or would you have to purchase a whole new pump.
concretedavey: Zoeller pumps are the best. The oil inside of submersible pumps is mineral oil. Couple of things. First rather than making the first section of pipe so short I like to run it so that it extends above the sump liner. Then the no hub and then the check valve. Also on the male adapter use never seize or a thread sealant so that it's easy to remove years later.
Frank Matturri: I agree with some of the comments below-you do need a vent hole, not only the manual tells you but I've spoken to Zoeller engineers. Also, with any kind of depth of your sump & a high water table, the pump will be running all the time since the float goes on so early and shuts off so soon. You will need a good quality separate float and just tie up the stock Zoeller float switch. I have had Zoeller float switches burn out very quickly.If this guy had them last that long they must have been installations with very little water. Zoeller pumps do pump water like crazy though.
Scotty Hayden: I agree. Separate switch is the only way to go...
Anthony Bonaventura: I've replaced dozens of these. Normally bad float switches.
terminal velocity: correction "zoeller " I hate auto spell check
terminal velocity: there is no way you didn't have to replace 1 speller pump in 27 years unless by chance you only put in 1 and didn't use it. They're not that good
