I was told by two different plumbers at two different times that Zoeller was THE brand for sump pumps.
They also told me that the ones you buy at the “big box store” are pretty worthless (you shouldn’t be replacing them every couple of years).
Unfortunately I do not recall the name or model number of the one I had installed ($360 including installation). I do know it was cast iron and submersible. I think they cost around $75-150 depending on who you are and where you get it from.
