Is the Zoeller M95 a new pump?

Michael

What is the difference between the M98 and M95?

Dino

from Illinois

March 31, 2017

Answer

The M95 is Zoeller's latest, greatest and updated version to the flagship M98 pump. Same dimensions as the M98 but with the following upgrades: Higher pumping capacity, 4800GPH @ 0'hd (compared to M98's 4320GPH @ 0'hd), improved switch for longer life, lighted plug, polypropylene made, a float-operated vertical switch w/ Viton® Switch Boot, and a FIVE Year warranty.

Is there a big difference between the M53 and M98 when it comes to noise and cycle rate? I have about 12 feet to go up from my sump pit, so would the additional hp help it not run as much with the initial float kick on at 9?"

Aaron H.

from North Dakota

March 21, 2017

Answer

Regarding the noise concern, there should not be any difference as long as the pump is installed properly. Regarding your cycle rate, it may actually increase since it will be emptying your basin quicker. It's always best to keep your cycle rates to a minimum when possible. So if the M53 worked well for you and you never came close to flooding, I would suggest keeping that 1/3HP pump in place. IF that M53 had difficulty with demand at any time however, then I would suggest increasing to the 1/2HP model M98.

What can one expect for your model M53 C to last in terms of years?

Rohn V

from Ohio

March 19, 2016

Answer

That's a tough question to answer. Typically, the pump should give you about 5-7 years of life in a standard sump application. That said, I have heard of them lasting 10, 15 and 25+ years in some cases. The switch is the most common reason for failure and can be replaced, though it is a bit involved on the "M" Series models.
If you have any other questions, please let me know.

Installing an underground sump pump to drain water coming under the house. Was thinking about ordering the following kit, but I am not sure if the basin is the correct one for a sump pump or if we should switch it to something bigger. Zoeller 1050001 13 HP M53 Remote SinkDrain Pump System w Vertical Float Switch Thank you, Nestor Ho

Answer

Thank you for your interest in Sump Pumps Direct. It really depends on how you plan on getting the water into the sump basin. If you are doing a typical basement INSTALLATION, I would advise something more like the Zoeller model M53 or M98, depending on your water table. I would then suggest installing a standard SUMP BASIN and COVER. You can then tie this in to a french drain or you can drill holes in the basin to allow the water to seep through and into the basin for discharge by the pump. If you are looking to install this system outdoors or in a crawl space, the Liberty 1/3 HP Cast Iron Crawl Space Sump Pump Kit, model CSP-257 might be a better choice.
And don't forget the CHECK VALVE.

I live on a small man made lake and have a walk out basement. Over the years the water table of the lake has risen to the point that the piers of my deck, approximately 100 feet from the water, have raised my deck about 4 inches. I dug a dry well near the house 2 feet deep. This dry well is constantly filled with water to within 6 inches of ground level. The dry well has underground drain tile running out to near the lake. I want to install a sump pump in the well to extract the water and hopefully keep my deck fro rising. Will the M98 be a good pump for this application or should I be looking at a 3/4 or even 1 HP pump. I expect this pump will run quite often maybe even close to continuously. Thanks for your help.

Answer

If you are mainly dealing with clean water and there is no chance of the water freezing with the pump, the M98 or StormPro model BA-50M would be a good choice to start with. Since it's difficult to judge just how much pumping capacity will be needed. If there's more of a chance of debris getting into the pump, you might consider one of our SEWAGE PUMPS as they can handle some of the small solids like leaves and small twigs. Please note that for any outdoor application, all electrical connections would need to be very well protected from the elements.

I want to replace my old 1/3 hp Zoeller with a newer 1/2 M98. Our pump has worked well but we got hit with a lot of water in the Sept 2011 flood (Lancaster PA area). The check valve double checked so I don't know if the pump would have handled that volume. The pump is old, has a 1 & 1/4 line out. Do you think replacement with a 1/2 hp upgrade would be ok? Fits in the well the same but would handle a bit more water per hour. Thanks

Bob Spender

from Pennsylvania

October 23, 2012

Answer

Due to the fact that you have a 1-1/4" discharge pipe, you may not see a big difference in your GPH capacity, though you will see some. If there's any chance of upgrading to a 1-1/2" discharge pipe, you would see a bigger difference. Also, depending on the age of the check valve, you might consider replacing that as well. They tend to wear out just like an old pair of shoes.

I would like to know how many watts a 1/3 or 1/2 hp sump pump has, because i was think of buying a portable generator in case the power goes off.

Tom B.

from New York

September 03, 2012

Answer

That really depends on the pump. Some are more efficient than others. For example, the 1/3HP Basement Watchdog model BW1033 has a running amp rating of 3.5 and a starting amp rating of 7. When you figure the watts by the formula of amps times volts equals watts ( A X V = W), you get 420 running watts and 840 starting watts. But when you look at the Zoeller 1/3HP model M53, that pump has a running amp rating of 9.6 and a starting amp rating of 29.6 or 1152 running watts and 3552 starting watts.

Jim, I've learned a lot reading these Q&As and the reveiws. A few questions for you - hopefully this isn't overboard, I'm rather new to having a basement... 1. My current sump pump is old and I'd like to proactively replace it. Based on where I live, and how active he heard my sump pump going off even after no rainfall for a while, a plumber/family friend recommended getting 2 high velocity pumps at least 1/3 HP (with 2" discharge). Even though this only has 1.5" discharge, based on reviews I'm sold on either this Zoeller or your Storm Pro 'Best'. I've also heard of some friends having someone out to 'install a battery backup' on their existing pump (apparently not a separate system including another pump). Is there a way to add a battery backup system on to these pumps, since I want those pumps but the security of a battery backup? Does this approach of 2 of the same pumps make sense to you, or should I be looking to get one of these and a battery backup system? 2. How much time do the battery backups generally give you? Thanks! 3.

Answer

Thank you for visiting Sump Pumps Direct. In answer to your questions, both the Zoeller and StormPro pumps are extremely reliable and well manufactured. The StormPro is more efficient however and will offer a higher pumping capacity. If you decide to go with, say the 1/2HP model BA-50M, there would be no problem reducing the 2" discharge down to a 1 1/2". A 2-pump system is fairly common when you want to have the ability of having a "secondary primary" pump in the event that the "primary" pump gets overwhelmed and is the best way to achieve excellent results. Just be sure to run a separate discharge all the way out for each pump. You DO NOT want to install one extra large pump like a 3/4HP or 1HP because during normal operating times, the high HP pump will cycle way too often and reduce the life of that pump. The only battery backup system that we would offer for your primary pump would be the SUMPRO Fully-Automatic 1800W Auxiliary POWER SOURCE which requires 2, 12 volt maintenance-free deep cycle batteries. At the cost of these systems, you might look at a regular BATTERY BACKUP sump pumps system or even a small 7000-8000 watt STANDBY GENERATOR.

The standard battery backup sump systems will typically give you about 7 hours of continuous run time or 24-36 hours of non-continuous (cycling) run time. There are some systems that will accept additional batteries to extend that run time, but it is available only on certain models.

I don't know which model sump pump to purchase or which model is appropriate for my home. How do I go about doing that?

Harry

Answer

If you are replacing a sump pump and the pump has performed well for you in the past, it's best to replace it with a pump that matches the horsepower and/or gallons per hour rating as close as possible. If that information is unknown and the original pump's brand and model number is still visible on the pump, you can always look it up on the internet or call us for more help. If no information is available, an average sized home in a typical water table can usually use a 1/3HP - 1/2HP sump pump. Submersible sump pumps are more popular and will usually run quieter and last longer than pedestal sump pumps. You can also click HERE for more information on how to pick the perfect sump pump.
If you have additional questions, please let me know or give me a call.

I am torn between which Zoeller pump would be best for my application. My basement is 104' and currently takes in approximately 3" of water when there is a hard rain. The water is only on one side of the basement and never comes up on the other. Would you recommend a 1/3 hp or 1/2?

Joe

from New Jersey

Answer

Without knowing more specifics like the water table, area of the country you live in, actual square footage of your basement, etc., it really is difficult to answer. I can tell you that most average sized homes in an average water table area can usually get away with a 1/3HP or 1/2HP pump. Beware of over-sizing the pump as it could cause the pump to cycle too frequently thereby reducing the life of the pump. You don't want to just install a 3/4HP or 1HP pump just for the sake of it.

I am considering buying a Zoeller m98. I am going to have it on a dedicated circuit my question is how many amps does the circuit breaker and circuit need to be. I see that the running amperage is 9.4 but I am concerned about having a circuit that will carry the starting load.

I have this pump: Zoeller M98 - 1/2 HP Cast Iron Submersible Sump Pump w/ Vertical Float Switch, I am on my 3 pump in 6 years. All the same pump. Each time the pump gets stuck in the on positon and will not shut off. Can I replace the switch? I just got a new one and thought I could fix the swith on the old one and keep for a back up. Also, isn't is strange that this keeps happening? Our pump runs quite a bit in the spring and in winter is we get rain or a big snow melt. I keep getting the same pump from my home builder who runs a plumbing supply company and get a good price. Should I consider a different pump?

Ryan Schmitz

Answer

The Zoeller pump is an excellent product but, the switches do tend to be the occasional problem. You might try calling Zoeller tech support at (800) 928-7867 for assistance in obtaining the switches. Also, you should be inspecting your pump and basin at a minimum of every 6 months to make sure the pump is operating properly and the basin is clear on any debris. Most switch failures are the result of dirt, grime or debris getting lodged in the switch and/or switching mechanism.

I want to replace our pedestal pump, which runs a lot due to high water table, and the zoeller M98 looks good. We have a rectangular sump hole in the corner of the basement, about 18 inches deep (est). What accessories would I need with the pump? All the covers I see are round, is there a rectangular cover available, and where does the check value go? Thanks!

Jim Shear

from New York

April 03, 2011

Answer

First off, it is recommended that you replace your pump with one that is comparable in HP and GPH(Gallons Per Hour). We only carry the round basin covers that will cover an 18" round basin. The check valve can be installed either at the base of the pump or just above the basin cover. Installing above the basin cover will make it a little easier to disconnect your discharge for any service. Also keep in mind that you should drill a 3/16" hole in your discharge pipe just above the discharge base to help prevent any air lock.

I am considering ordering a back-up for my thirty-year-old Sears Craftsman 1/2 hp submersible. So far this unit (Zeoller M98) looks to be the best fit in terms of size, capacity and quality. Can I reuse the Craftsman solid state controller? The reason why is, I like that I can precisely set the cycle on/off level, using these little probes that run to an A/C line controller. I'd re-buy that exact same Craftsman unit again, except they don't make it anymore.
