Water under high efficiency furnace - condensate pump recommendations

I have a Lennox G71 modulating high efficiency furnace. Came home today and found a small amount of water coming out from the bottom of the furnace. It appears that the water is solely on the ground under the furnace and not inside the furnace dripping down. I cannot get the condensate pump to turn on even after I put a little more water in it. I also tried a different a different outlet just to make sure. I have a Diversitech CP-16 pump. I just read a bunch of reviews on it and it appears many users have experienced very short life spans on this brand pump.

What would be the most reliable condensate pump to replace this with?

Thanks
