## Description

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.

Review: Reduced water hammer, Easy to install. - 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.
Review: Great sump pump backflow valve - Love it works great, replaced an old plastic one. It’s quiet and works as stated. I would buy again if required but this one has been installed and working for 3/4 of a year without issue!

### ⭐⭐⭐⭐⭐ awesome Zoeller check valve
*by R***. on 2 October 2018*

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.
