Poor product

Two and a half years ago I purchased and had a professional install a Zoeller sump pump model 1075. I needed something reliable. I thought this would be a good choice. Three times the float stuck and I had to deal with flooding. I put a high-water alarm on it to at least let me know when it was not working. That saved me two more times, once I was out of town and had to rush home and got there just in time before the flooding did damage. Last year I contacted Zoeller and asked what I could do to avoid the float from sticking. They said someone would contact me. No one ever did. I have been thinking what to do about it when it happened again. This time the float not only stuck but the float post and the float came detached from the pump. I have taken the pump out of the pit in hopes that I could see what the problem was and fix it, or get it fixed. So far I have not been able to. Zoeller has no services centers closer than over 100 miles away. I would not expect a product to give me so much trouble and fail so quickly after purchase. I am very unhappy with the product. The only solution I see now is to purchase another pump from a different manufacture-one that has a longer warranty than two years. I should have known that with such a shout warranty Zoeller must have little faith in their product. I wanted you to know how totally disappointed I am with Zoeller.

Great Unit

My 1/3 HP sump pump died in a heavy rain. Bought this 1/2 HP unit and my plumber installed it for me. (properly). This pump ran through the backed up water in less than 5 minutes. Powerful!

Great pump. Even under severe conditions.

Pump works great even when abused . Probably a little too small for what I use it for. I have a French drain into sump in back yard and pump 200ft up 10ft to drainage area. During really heavy rains this pump is too small for my drainage system and is fully submerged to the point it will take a 4 or 5 hours to pump the water off enough for pump to get a break. I have had this pump run for 16 hours straight before and never had an issue with it. Cycles on and off as intended.

do not buy

Wow, it looks like this happens a lot. After 2 or 3 weeks, it stopped working. After tapping on the pipe, it started working again. As other people have suggested, it must be the switch. Since I'm not going to live in the crawl space, I took this back to the store, luckily it was within 30 days.

Great until it aint

Same as many others have echoed I've had problems with the switch. I've 2 of these and they worked fine for about a year.the pumps seem well made and pump water well,but that's not helpful if it never comes on. I'd bought these because they were supposed to be better than the drummond( harbor freight) pumps,but the $89 harbor freight pumps lasted for more than 5 years before I had any failures. At 3x the cost I'd of expected alot more from zoeller.

Float switch gets stuck

I bought this pump a few months ago. The float switch started sticking on and off within a few weeks. It seems this switch is a magnetic reed switch. The magnet is floating up properly, but the switch does not always actuate / deactivate properly. Recommend choosing a pump with a mechanical switch.

What a liability.

We had this pump installed for a little over a month. In that time it failed twice, both times flooding our basement. Each time the issue seemed to be isolated to the float switch not working smoothly... you might as well pay someone $250 to fill your basement with water and save yourself the surprise.

Pump quit after less then two month.

Do not buy. Pump float stuck in the up position and basement flooded after only less then 2 month after installation. Buy a Wayne or other brand. I am not the only one who has experienced this. Do not buy.

Follow up on M98/98-0001 and 1075-0001.

See my previous 1 star Jan 10, 2024 review. If you need to repair the switch on a M98/98-0001 or similar, you may want to try the repair assembly (switch) Model: 004702 which is less than a new pump. As for the 1075-0001, my pump, new out of the box, failed in about 2.5 weeks. The switch failed to turn the pump on. Don't buy this model pump until they fix the switch issue or risk a flooded basement. I'm going to buy a new 98-0001 and the repair kit for my old 98-0001 as a backup.

Quiet and powerful

During a recent 3 inch rain storm, our original “builder’s grade” pump stopped at the worst possible time. A friend who had just finished renovating his home highly recommended the Zoeller brand of sump pumps. It was easy to install and is nearly completely silent in operation. Very happy with my purchase!
