Zoeller Pump Company’s Model 98 Sump Pumps can offer protection and prevent flooding after heavy rainfall or storms. Underneath your structure, pits collect water. If the water level reaches a certain point, automatic or manual settings on the machine can efficiently pump that water away from your property’s foundation. How often the pump runs depends on the amount of moisture in the space. A corrosion-resistant finish over cast iron construction provides incredible strength and durability, and stainless steel screws assembling the seal, arm, handle, and guard stave off rust. The pump uses a 1 ½-inch discharge pipe and can pass spherical solids up to ½ inch in diameter. The lack of screen keeps the unit running smoothly. We offer accessories such as alarm systems with simplex or duplex control panels designed to keep you informed about your sump pump’s water level. The alarm gives you peace of mind that your pump is operating as intended.

Arrived in lightning speed and no issues installing. However, showing us a picture of two items is misleading.

I bought my home and in the inspection was a "Faulty check valve" on one of my sump pumps. It was a PVC kind that was probably around $3.00 at your home store. I have never lived with a sump pump before so the noise that would come from this pump was startling. It was extremely loud even on the second floor of my home. It was odd too because my other pump already had one of these check valves on it and didn't make that loud hammer noise!Based on reviews here and that I already had one, I decided to try another one for my problem pump. Install couldn't have been easier. Done in about 15 minutes (excluding the trip I had to make to Lowe's to get an adapter). The valve comes with couplers that are 1.25" on one end and 1.5" on the other. The problem I had was that the sump pump discharge pipe is 1.5 pvc and north of the check valve is 1.25 copper. So for the top part I needed a straight 1.25 to 1.25 coupler. After installing this (and literally, if you can turn a screw you can install this) i filled up the sump crock waiting to still hear the loud hammer... But no hammer was there! I could barely even here when the water hits the check valve when I was standing right next to it. Can't wait until I'm three floors away to hear the difference but I doubt I will get to appreciate it because it is so quiet. I will have no clue the pump has cycled on unless I'm in the basement. Great value and great quality.

I have purchased several different check valve's from the local big box store. They all leaked internally. This unit seals like it should. Problem solved.

My dad was a plumber this is the only brand check valve and pump he would use. It's better quality than others. Very durable will outlast the competition for sure. Easy installation!

My sump pump had an old check valve installed that no longer worked. Everytime my pump would activate it would empty the sump but all the water in the pipe would return because nothing was stopping the backflow. We recently lost power at our house 3 times in five days so I decided it was time for a backup pump. Since I was adding a backup pump it made it a good time to replace the broken check valve. I purchased two of these, one for each pump (main and backup). They were suggested by Amazon to be purchased when I added the backup pump to my to my cart and based on the reviews I decided to purchase them as well.Pros:Easy to install for a DIYerPrevents water from re-entering my sumpCons:There is a small knock /tap sound when the internal flap closes. That is normal for these type of valves and the sound is not too loud but it is noticeable. I have an unfinished basement with a livingroom setup so I can hear the knock but if you have a finished basement or do not go into your basement a lot, then I suspect that you will not hear the knock.

I've used several of these between different projects now, simple, works and can be used with 1.25 or 1.5" pipe.

Why didn’t I do this a decade ago?!Much quieter than the older unit, zero water flowed back through into the sump, and Amazon had a great price compared to the box stores.

I have bought a lot of check valves and this one has not broke yet. Usually the ones you buy in local stores only last maybe 6 months. I have an extremely extremely extremely very high water table. 6 months ago they dug a new basement for my new addition and the builder was in shock. dug the basement and then left for 12 hours and had a full blown pond the next morning. So this check valve is the #1 best in my book period. my sump pump in new addition was kicking on every 20 seconds for months. for the existing portion of the house we have 2 sump pumps that are kicking on every 3 to 5 minutes especially if the ground is moist or raining. kicks on every 10 minutes if so called dry outside. and YES I have it set below the holes in the sump pumps to kick on so the water is not filling the lines up and making it work twice as hard. This check valve has last the longest so far. I bought one Zoeller check valve from amazon and one Zoeller check valve at Walmart on the same day and just waited to see which one was going to get here the fastest. I had 1 sump pump shut off because the local store check valve tore again and water went every where, so that made the other one in existing portion work twice as hard. I didn't want both to go out before the NEW check valves got here or I would have a pond in my basement. Then I replaced them and I am a happy camper now.

This ad makes it seem like you are getting two, but you are only getting one.This is a good product, installs easily, and works well. The flap is steel, which is much better than plastic.Again, be aware that this is for one valve, not two, as pictured.

Works as a one way valve should. Simple fabrication. No fasteners in it anywhere, which seems like a good design. The one it replaced had 4 bolts holding two pieces together, which simply started leaking eventually.Only complaint is that it isn't whisper quiet as some may suggest (at least in my experience anyhow). It isn't SUPER noisy but when the pump shuts off, there is an audible thud from the valve stopping the water. Certainly quieter than the one it replaced. I need to buy another for the backup sump, and will buy this again.

Was a bit leery of getting something that wasn't sold or supported by Amazon, but it was a great buy. As others have said, it is a 5 minute job to install and it is absolutely silent. My contractor initially said my hammering was due to my sump pump, but I figured it was likely due to the water hammer with my check valve and I was right. I was thinking of somewhat more expensive "silent" check valves, but I'm glad I picked up the Zoeller - it has been silent (the water rushing through the pipes is louder!). Also, shipping was fast (I bought it in the GTA), fwiw. Have had it running for a few months now w/ no issues.
