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!

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

So far so good. I got two of these and put them in the same pit. One three inches higher to act as a backup. I really like this pump.

The switch on my old M98 stopped working after a year so I hope both of these last much longer. I also had the M53 and that worked but the M98 drains the pit much faster. The supplyhouse is great to deal with, they took my old pump back it was still under warranty no questions ask and shipped me out this new M98. I also bought the second one for a backup. Even after my last pump broke, I would recommend this pump. Well built and it drains the pit better than any other pump I used. And I have used many.

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.

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.

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

    Q:

    9.4 running amps is higher than most competitor products, but the startup amps of 29.2 seems out of line. I am not well versed on these ratings except that most house current is fed thru a 15 amp breaker. Can you explain what electrical requirements are for this product. It appears to my none electrical mind that you would need a 40 amp breaker and an appropriate size wire.

      It's a good question. I've had mine running on a 20 amp breaker and it's

      A:

      Just the facts! I installed my Zoeller Model M98 Sump Pump on July 14, 2013. It is plugged into a Ground Fault Circuit Interrupter on a separate branch circuit with #12 AWG copper wires running to my electrical box with a 20 amp breaker. During this period of time the pump has never tripped the breaker. For your technical question regarding 29.2 startup amps, I suggest you call the Zoeller Pump Company at 1-800-928-PUMP. Happy pumping and “MAY YOUR WATER FLOW IN THE RIGHT DIRECTION!”

      A:

      I'm pretty sure mine is on a 20A breaker. I'm sure it is not more because
      that is the highest in my box excluding the dryer and AC double breakers.
      I believe some breakers are designed do work with large transients like
      motor start without tripping. There is always a compromise of some sort
      between fast acting and false trips with glitches. You might check with
      your electrical supply store ask about what different types of breakers
      they offer. But 20A is plenty. Typically the 20A refers to the running
      number. There are different types of breakers and some of them are
      twitchy. But motors and breakers have been around for a long time, so it
      isn't much of a problem.

      A:

      I would not worry about a high amp draw at start up, it is
      so brief that a 15 breaker has no trouble handling it. I purchased this pump a
      couple years ago to replace a two year old top of the line stainless steel
      & cast iron Flowmaster. The Flowmasters motor burned out and flooded my basement.
      During a pair of two week power outages I had the Flow-Mate
      running off a generator with a 20amp circuit. Even with two refrigerators,
      sewage pump, furnace, multiple lights drawing from the one generator circuit the
      Flow-Mate would not trip the breaker when it kicked on.

      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.

      Answered on 6/28/2011 by PexSupply Staff from NY
    • VERIFIED BUYER

      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.

    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.

      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.
