Sump pump recommendations

I'm looking at getting a new sump pump and I'm torn between the Zoeller and Liberty pumps. I need to use a float switch so I will probably get a pump with a built-in switch instead of hooking up a separate switch. I've heard good things about the Zoellers, however their float switches have a bad reputation, hence considering the Liberty.

    Little Giant

    I went with a Little Giant though my pump may never even turn on except when I drain the boiler (cold) into it.

    They have a wide range of pumps including brass ones for over $700.  I would recommend avoiding the piggyback style switch which is a single float on a electrical cord, they kind of suck.


    Liberty also makes a pretty wide range of pumps including good ones.  Zoeller I think makes, or at least used to make a good pump but I too have heard a lot of complaints about switch failures.

    I've had goo luck with Glentronics pumps


    The float I have is on a wire and mounts to the discharge pvc line with  a clamp. Also has a little alarm box that sounds if the float( there are two in the cage) sticks or if the pump fails to remove water within allowed period. The mounting scheme allows for easy adjustment of the float level. I have the 1/2 hp one. Have had it for 5 years and so far no problems. Glentronics make a wide range of pumps all are good. The ProSeries line seems to have the best price/performace bang. Many online places have them. My 2 cents.
