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.
Ironcurtains: correction "zoeller " I hate auto spell check
Ironcurtains: 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
Ironcurtains: zoeller pumps are the best but their switches are THE worst. Listen to rustyme112. Get a separate switch. I have collected over 20 pumps that people have thrown out thinking they were shot but its only the switch.my plumber friend gives them to me and I fix the switches
rustyme1122: Agree the switch is more likely to fail than the pump itself. I personally prefer the Zoeller pump without switch, and use a Rhombus vertical master float switch. Zoeller switches are rated 100,000 cycles. Vertical master is 250,000. Problem I find with all submersible pumps is lack of depth adjustment. They all only pump about 6 to 8 inches of water level. I was able to modify the vertical master and now get about a full 12" of pump down.
hopcup1: sorry.. u been doin this 27 years ? y would u put the no hub down all the way into the pit? so its harder to work on??.... u keep all ur connections above the pit so its easy to get to and work on.......... sorry but lousy video.. somthing a handy man would do
hopcup1: its not near the best pump... i installed tons of those my self.. and the die to easy... they r not worth for the price....
gatekeeper2012: any one on what type of oil goes inside the motor????
tc1uscg: Though the pump may be the best, how about the float unit? I understand thats the weak spot of most pumps. I currently have a Ridgid 1/2 hourse but replacing it with a 1hp Coleman. Last time I replaced the pump, I cleaned out the discharge pipe up to where it leaves the house. Lots of buildup. I'm concerned it could have more build up from the house to the storm drain. Is there a good way, ie. using a snake, to clean out the rest of the pipe?
TooL KikS: I had a zoeller when I moved into my house, 1/2 HP, the float switch started to stick. I upgraded to Storm Pro sump pumps and battery backup. zIts 1/3 hp but pumps more water than the zoeller...at only 4.5 amps. I couldnt run the zoeller on a 2000 watt generator, power hog.
