I have a home sump pump installation that sits idle most of the time but after soaking rains becomes critical. At these times the pump can come on 2-3 times a minute for hours tapering of over a day or two. Our local plumber recommended this exact make and model. His company installs these and considers them the best and only choice. It is extremely well constructed. It has a cast-iron housing. Everything about it seems built for the long haul. It installed in about 1 hour. I followed the instructions with no problems. Very happy with the results following its first live use!

not designed for heavy use
we use this item in a carwash pit and it does tend to run a long time and we had failures due to that. good pump but not designed for long running times

Comments about Model M98 Flow-Mate Automatic Cast Iron Effluent Sump Pump - 115 V, 1/2 HP:
Fantastic upgrade to existing Zoeller M53-0001 Sump Pump. This M98-0001 is a whole different size and class of pump sitting side by side with its little sister the M53/57. Would recommend the extra money for this larger and more capable pump in areas that see heavy rain fall like here in Iowa. I'll sleep better the next time we get 5" of rain in 24 hours.
Bottom Line Yes, I would recommend this to a friend

Dependable Strong Pump
from Rhinebeck, NY
Dependable Strong Pump that with the 1 1\2" or 1 1\4" output removes a large water volume every time it runs. it does a great job. In addition, the SupplyHouse was very quick in processing & delivering product after I had placed the order. Good Customer Service.
Zoeller M98 sump pump review/performance
from Glenview, Il
Our home is a size able ranch which means our roof sheds double the rainwater of the same size 2-story home. As a result we have a high volume of water that our sump pumps have to handle during these now common storms when we get 4-6" of rain in a few hours. I had Zoeller M53 & M57 pumps prior and still had a problem with not enought pumping capacity during major storms. I installed the M98's recently and WOW, do they pump tremendous volumes of water very quickly. Literally in less than 1/2 of the time to empty the sump pit than the M57! They are also quieter when running as well. One recommendation, be sure you have a 20amp circuit for the pump since they do draw a few more amps when they start up. 15amp might work but you don't want a tripped breaker to shut your pump off during a rain. Exceptional quality and now finally peace of mind!

Solid Performer provides peace of mind!
from Neenah, WI
The M98 has performed flawlessly since installed. So well that we purchased two others to replace our old pumps. That's right, we have 4 sump pumps. Shipping was fast and the pumps arrived in perfect condition. Great buying experience.

zoeller pumps are good quality
By carwash king
i use this product in a carwash grit pit as a back up pump on busy days and it does a great job. they had issues with a few older models and they have come good and warrantied them.
Extremely quiet. Heavy duty.
from central PA
This pump is very quiet. A great upgrade from my 1/3 hp pedestal pump. This thing moves a lot of water quickly. Very glad I chose zoeller, pump looks to be built well. The only thing I dislike about it is the way zoeller attaches the float rod to the bottom of the pump. They use a piece of rubber strap for this. All things considered I think it is a great pump.
Very quiet and fast
This pump replaced a 1/2 horsepower wayne pump. It is so much quieter. I purchased this with the Zoeller stand. it was nice to be able to raise the pump up without using unstable bricks and blocks. Empties the sump very fast. It does not have to cycle as much as the old one.
will be buying another soon as a back-up
from Ontario, Canada
we live in a high water table and need something reliable. had a [@] pump that died in less than 18 months. Pump came in days, easy to install, price was good. have had steady rain and snow melt since I installed it - pump has been running constantly, no problems. will most likely buy another as a back-up.
