I'm giving 4 stars due to the fact it's a sump pump and I tested it and it works so I installed it because I got rid of my other pump it was a tether pump and when the float came up sometimes it worked and I felt it was time to change before it was too late, and it was also a 1/4 hp and I decided to go a little bigger from suggestions and I also did a lot of research and it was a decision to make and the tether float arm get's stuck in the pit if it's not in the proper position so I went to a vertical pump which has a guard and is protected.The only thing is I had to change the height on the pump in the pit or it would run as soon as a little water got in the pump due to the tether arm reach on the other pump so I just built it up a little and changed the pipe a little,other than that I think it was the right choice once again a Zoeller got good reviews and I hope it does it's job....
I Allready install this sump pump & it works perfectlythanks for the GOOD productalso thanks for the fast delivery
I have two of these in my home. One is in the sump for the weep tile, which pumps out ground water that seeps under the foundation, the other is in the utility sump, that pumps out water from the basement drains, washing machine, and furnace into the overhead sewer. The weep tile pump gets quite a workout, as the basement is slightly below the water level of the soil for most of the year. It gets used constantly.I've used these Zoeller M53 pumps since the house was built 30 years ago. On the weep tile pump, which is used between twice per minute and once per hour year round, we consistently get about 7 years out of the float switch, which gets replaced and we get another 7 years from the new switch. I replace the entire pump after the end of the second switch, but I could probably replace the switch again and get another 7 years. On the pump for the overhead sewer, the original pump lasted 29 years!I'd say that these pumps are outstanding. They are American made and more expensive than imported pumps, but they are well worth the extra cost for the incredible long life and reliability, not to mention giving Americans a job.Because the weep tile pump is so important, (we'd have a flooded basement in minutes if the power were to go out during a storm), we have a battery-backed up pump in the pit. This has saved us numerous times when the power went out or the sump pump float switch was at end-of-life. The best backup pump for this is the "Basement Watchdog", which has a pumping capacity almost as high as the Zoeller pump. Make sure to consider this when selecting a backup pump, as many of the competing brands can be overwhelmed during high usage (like a storm). Make sure to compare pumping capacity at 9 foot lift (head), because that's how it's used, and not the inflated numbers at zero lift.With the combination, I've had a dry basement for 27 years, and that's with the challenging situation of having a basement below water level in the midwest!
I had the Zoeller m53 sump pump installed in Aug 2005 and had never cleaned or checked it until July 2016, I may replace it next year with another Zoeller m53. It is a connecting outside drain to sump pump located inside the wash room.
I currently have this product installed and it is performing well, but since this is a 'backup' and won't be installed until needed, I have concerns about damage caused in handling. Please see my delivery comments.
Original lasted 11yrs. And decided to replace with same brand and design. Easy installation.
I purchased this as a replacement pump for an existing under-sink installation because I could not get the float assembly to work correctly on the original after about 5 years of service (and I didn't want to replace the whole drain basin and plumbing.) The pump itself is fine, strong and quiet, but the vertical float assembly is poorly designed and becomes unreliable because it is too free to move horizontally on the bottom (it is located by a cheap rubber strap.) If possible, purchase one of the models that has a tethered loose float (that swings up as the water rises) it will probably work much longer without problems.
Great Unit
I have one in my sump pit right now and expect it to do the job for quite a while. We always use these pumps while draining pools and they never had trouble getting the last of the goo out of the bottom, even pushing twelve feet up to get it out.
The Zoeller M53 pump was easy to install. So far the product works great.
Great sump pump, can't get this quality at your local hardware store.
Same thing happened to me that others are complaining about. Switch failed and wouldn't shut off.
The pump rusts easily, water goes into switch housing, and then it heats up and malfunctions
My mom has one, has been very reliable.Heavy duty cast iron.Made in USA.Seems most plumbers recommend it as well.
Had 2 M-53-0 Pumps Installed in Basement Both of them lasted 8 Months, Strap on float broke on one, the other pump just stopped working. Called Zoeller and got the run around, They Don't stand behind what they sell. Don't waste your money they are outdated and unreliable.
The pumps on these units have a lot of power and work very good. The float switches are the constant source of failures on these pumps in my 15 years, of working with this brand. I own 3 of them. The switches either get corroded, burned-out, or they get sticky and fail to work. The rubber surrounds also dry out, crack and leak water into the electrical compartment. The floats can also get coated with crud, which weights them down, so then your basement floods. I have complained about these float switch failures to Zoeller and they took a blind attitude towards the issue. They said to tie the float up and use an external float switch instead. They might just have told me to go out and buy a competitor's product instead. I said why don't you get away from the out-dated design and use a magnetic hall effect sensor, or other electronic means to sense the water level? They will keep selling this out-dated design until they go out of business. This company lacks any innovation. These units last about 5 years under moderate sump pump use.
This is a replacement sump pump of the exact same thing so it was sooo easy. Purchased this product because the other one lasted about 11 years.
I am replacing the second pump of this type now - have three of them. They have lived for about 10 years, then corrosion lets water get to the switch and it either won't turn on or it won't turn off. Pump housings are covered with thick layer of rust, but if it were not for the switch these things could have a much longer service life. Still recommend it because the price is right but you must keep an eye on these things or have an alarm to keep your basement from flooding.
Great performance, reliable, and low cost. Everything you need in a home sump pump.
Easy to install and maintain.
Installed this pump to replace an older version of the same model that had been in place for at least 20 years. It works great and I expect the new pump to last at least as long.
