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!

Dependable Strong Pump

Comments about Model M98 Flow-Mate Automatic Cast Iron Effluent Sump Pump - 115 V, 1/2 HP:

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

By Dvredc5

from Glenview, Il

Verified Buyer

Comments about Model M98 Flow-Mate Automatic Cast Iron Effluent Sump Pump - 115 V, 1/2 HP:

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!

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.

Comments about Model M98 Flow-Mate Automatic Cast Iron Effluent Sump Pump - 115 V, 1/2 HP:

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.

Comments about Model M98 Flow-Mate Automatic Cast Iron Effluent Sump Pump - 115 V, 1/2 HP:

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.

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.

Amazing Pump & Easy to Install

Comments about Model M98 Flow-Mate Automatic Cast Iron Effluent Sump Pump - 115 V, 1/2 HP:

Pump was light weight and easy to install as a replacement product. Even though it has been in use for a short time, the efficiency is noteworthy. Quiet with enough horse power to rapidly pump the water reservoir.

      A:

      I don't know more than what the spec sheet says. It says 9.4amp running
      and 29amps starting.
      I'm guessing that is under load though. Watts = 9.4 x 115Vac = about
      1100W. I find this hard to believe though. That implies a very
      inefficient motor. One horsepower is about 745W. Usually electric motors
      are at least 70% efficient if not much higher. This implies a 30%
      efficient motor.
      For my purposes, it only runs rarely with cold water. I had the Zoeller
      1/3HP pump in another location for 20years with no problems.

      A:

      The M98 requires 29.2 amps or 3,358 watts for its initial inrush of current to start the pump (If sizing a generator this should be used). Once running, the M98 has a full load amp draw of 9.4 amps at 115 volts
      or roughly 1,081 watts.

      This would depend on the piping system (vertical rise, fitting used, horizontal run, etc.).

      Answered on 6/28/2011 by PexSupply Staff from NY

      A:

      Hi Vorchek,

      Well it depends on the 'dynamic head' (i.e., how far above the water level is the discharge point) - which will of course vary from (presumably) just a few feet at the start of the pool draining, and grow to perhaps 10 - 12 feet near the end. So at the beginning the pump will discharge at a higher GPM rate than will be the case later in the draining, when it is being asked to lift the water higher and higher above the water level.

      If my assumptions, above, make sense - you can expect an average of about 60 GPM over this range of 'vertical lift'. If you had a 30,000 to 35,000 Gallon pool, you would estimate something like eight to 10 hours... Hope this helps.

    Q:

    Will this pump still operate if the water has dog hair in it? We run a dog grooming salon and are looking for a different way to remove dog bath water, so there's quite a bit of hair.
    Asked on 3/30/2011 by Tim O. from Lewiston, ME

    • CUSTOMER CARE

      A:

      This pump will still function with dog hair. There may be an increased risk over time of binding between the impeller and the seal, but the pump should be okay if it is used with caution. More abrasive hair (hog hair, for example) tends to cause issues with these pumps.
