    • Reliable and Efficient Check Valve
Size: 1 - 1/2" Style: 1-1/2-Inch ABS Check Valve
This check valve has proven to be a reliable addition to my sump pump system. It works seamlessly, ensuring that water flows in the right direction and preventing any backflow issues. The installation was straightforward, and it fit perfectly with my existing setup. One thing I really appreciate is the durable construction of this check valve. The black plastic material feels sturdy and well-made, giving me confidence in its long-term performance. It operates quietly, which is a bonus since it doesn't add any noise to the sump pump's operation. You do want to make sure it's properly aligned during installation to avoid any potential leaks. However, once in place, it performs flawlessly without any issues. I believe this check valve is an excellent choice for anyone needing a reliable check valve for their sump pump system. Its durability, ease of installation, and efficient performance make it a top-notch product. ... show more

    • The check valve works and operates quietly
Size: Pack of 1 Style: ABS Plastic
I purchased this check valve with a Superior Pump 91250 1/4 HP Thermoplastic Submersible Utility Pump. I installed the valve, along with the 1.25 inch adapter, on the pump and put the garden hose adapter on the output side of the valve. I hooked up a 50 foot 5/8 inch garden hose and lowered the whole assembly into the water. I turned on the pump, and it worked fine. But when I turned on the pump a few days later, it wasn't discharging any water. I pulled it the assembly out of the water and removed the discharge hose and check valve. I couldn't find any problems (the valve seemed to be working as designed), so I hooked it back up and put it in a bucket of water to test it - when I turned the pump on, it shot a stream of water in the air, so I hooked everything back up and put it back in the standing water. When I turned on the pump, it again worked fine. A few days after that, I turned on the pump, and again no water was being discharged. I took the valve and adapters apart again, and this time I used Teflon tape on the threads before screwing it back together. Then as I was tightening the fittings, I heard a "pop" or cracking sound, and I thought I had cracked the valve body or an adapter fitting. But When I put the pump back in the water and turned it on, it pumped fine without any visible leaks. So I guess I was lucky. I have used the pump a few more times, and it now seems to work every time. Apparently, you need to seal the threads to assure everything works reliably - I would understand this being an issue if the fittings were on the input side of the pump (to prevent it from sucking air and losing its prime), but I'm not sure why a "perfect" seal was required on the output side. In any case, I thought I'd pass along my experience in case anyone else ran into similar problems. Overall, I'm happy with this check valve and will probably purchase it again if I need another utility/sump pump. 11/23/2013 Update: I purchased another one of these check valves along with another sump pump (Superior Pump 92372 1/3 HP Thermoplastic Sump Pump with Vertical Float Switch) a few months ago and put them into service - I have used this pump/valve combination with both a small (5/8") garden hose and a large (1-1/2") hose for the discharge. The inclusion of the two 1-1/4" to 1-1/2" pipe thread adapters makes adapting the valve to various inlet and outlet sizes simple. The 2nd check valve (and the sump pump) have performed flawlessly to this point; therefore, I am very pleased with both of these check valves, and I am revising my overall rating from 4 to 5 stars. ... show more

    • Inexpensive and works
Size: Pack of 1 Style: ABS Plastic
I'm using this Superior Pump 99555 Universal Check Valve, Plastic, Fits all 1-1/4 or 1-1/2 MIP or FIP x 1-1/4 or 1-1/2 MIP or FIP as part of an irrigation system. I was a little skeptical when I ordered it because of its price and material. We live outside city limits and rely on well water for home and sprinkler system usage. I have always used brass, spring-loaded-close type valves and they can be quite expensive. This valve doesn't have a spring. When the water pump is turned on, the suction unseats a flapper valve inside the check valve, allowing for the water to travel to the pump. As soon as the water is turned off, gravity takes over, seating the flapper valve and in the process prevents the water to flow back into the reservoir. We have close to two acres of land and the farthest side of the backyard was in need of an irrigation system. There's a water canal running parallel to our backyard, so we had a pump installed and used this check valve on 1 ½" PVC pipe. The pump has a 1 ¼" inlet, but 1 ½" inch pipe reduces the friction as the water travels from the reservoir to the pump. At the pump inlet, we installed a 1 ¼" x 1 ½" adapter. Water level from the canal to the pump is about 17 feet. We installed the check valve about three feet from the reservoir or 14 feet from the pump. The first and second time I tried to prime the pump, I managed to fill up the pipes and the pump with water, but when I started the pump, just a small drip of water came out. After the second attempt I knew something was wrong with the check valve as it wasn't containing the water within the pipe. After removing the check valve, I noticed the flapper valve was pushed out to the wrong end of the valve (opposite to the arrow on valve). Not sure how it happened, but it was stuck open and wouldn't seat. I used the handle of a screwdriver to push the flapper back to the front side of the valve...direction of arrow. I reinstalled the valve and after a few more attempts the water began to flow. So far everything is working just fine. I know that a least one reviewer mentioned about the valve failing after a short time of use. The one thing I can think of that would cause issues with the valve would be something stuck in between the flapper seat, e.g. dirt, debris, twigs, etc. Also, as someone here mentioned, you have to make sure the valve is airtight. The valve fittings have rough threads which can allow air to sip through; using Teflon tape is a must to create a watertight seal. ... show more
